Reliability issues on 6TB internal HDDs?


Recommended Posts

I'm looking at buying a 6TB internal HDD as i currently have 1x 1TB & 1x 2TB drives taking up 2 slots in my PC and i'm thinking i could double that in capacity and half the occupied bays.

 

After doing some reading on them the past week or so i get the impression that they can be a bit flaky in terms of reliability? 3TB (not that i'm interested in one) & 6TB aren't the best in terms of reliability but 4TB is kind of like the sweet spot.

 

But i prefer to chat with real people rather than swallowing articles, so what's the opinion from you guys?

 

From what i've read i would ideally prefer the WD Black 6TB but it's just the price that bothers me.

 

Alternatively Seagate IronWolf, Seagate BarraCuda and Seagate SkyHawk are cheaper, although i'm not sure if there's any major difference between the three other than £20. Sticking with WD is the Blue drive, though this is 5400rpm so i'd rather not.

No ... just no (w/ respect to 3 and 6TB being more/less reliable than other capacities).  What is the intended purpose of the 6TB drive?  Black drives are awesome, btw (+5 year warranty).

Well i did think that (replying to your "no"). As i was digging deeper it seemed to be like x-amount (small number) in y-amount (absolutely massive number) which made these 'failures' kind of like, big deal, the chances are slim. I just wanted some real-person feedback first though.

 

Regards the intended purpose, a large chunk, if not all, will be blu-ray ripping. That, DVDs, my music library as i get more & more in to this whole Plex thing. The few blu rays i've ripped already have taken a large portion of my 2TB drive remaining space.

 

The original idea was to have a section of the drive for that (movie & music library) and another partition for storage for day-to-day files like pictures i may save off the internet, documents etc, but as i think about it the 6TB may be better being solely dedicated to being where i store all my movies and music, the existing 2TB drive being where i store my documents, pictures etc and the 1TB being put in a drawer somewhere for 'just-in-case' purposes.

OK, I was just going to say that for media a 5400 RPM is just fine ... like a Red or whatever (three year warranty).

I like speed though :)

 

What would you suggest the black is better for then?

 

 

To be honest i don't use the storage drives a whole hell of a lot. I'll save music/videos/photos/documents there sure but i'm not constantly writing & reading from there. I don't do any intensive video editing for example.

Blacks are arguably the better of the consumer grade HDDs.

 

Though, once again, you could probably save some bucks and get a slower HDD (5400) if all you're doing is storing media.  I have Reds in my HTPC ... they run cooler and use less power and I doubt you could tell a difference (for media) between them and a Black.  I have a Black in my desktop ... but I have a few applications and some older games on it so the speed difference is more noticeable.  Then again, if money isn't of concern ... Blacks are the way to go.

I personally have 3 Seagate IronWolf 6TB drives in my system.  I've had them running for at least the last 2 years, and they've not had a single hiccup during that time.

 

But that's just me and the way I tend to work my system...

From doing plenty of Googling i think WD seems to get the split but not overwhelmingly so. Question is red or blue, i'm not so sure yet.

As i'm not a heavy user i don't imagine that i'd have any major issues unless i'm very unlucky. I see more complaints about Seagate though than i do about WD. I actually have a couple Seagates in my PC, a WD and a Samsung and i've had no issues with any.

Awesome.

Between a Blue and a Red  ... the Reds.

For what it's worth,  just won a Seagate 8tb from a Twitter Contest,  Immediately went in external enclosure for backup/storage,  Contemplating a WD Black 1-2 TB internal to replace my Toshiba OEM 1tb internal, not that anything wrong with it, just thinking prefer a Black Western Digital 7200 drive for my extra game storage, music folder, documents, pictures, and image off and on to the 8tb drive 

 

I feel you can't go wrong though with WD Red (though never used one personally) heck haven't even used a WD black yet, but am getting one for birthday that's for sure

Awesome

Was going to clear something, but Jim said it all. So nvm...

 

To say the least, I have both WD and Seagate, and several of them failed anyway

 

(lot of my seagates are old PATA drives anyway...)

(One WD actually failed, but that was my fault. Something fell on it and hit the platter...)

Edited by Mindovermaster

I don't want to jinx anything but how likely are failures?

 

I've had computers with hard drives since somewhere around 1996-1998 when at least amongst friends my 2.1GB hard drive was considered large.

Now ok i've not had 1000s of drives since then but i've had a fair few, both internal and external, 5400, 7200, SSD, SSHD, portable, desktop (ok the desktop isn't really that old).

 

And to date i've never had a failure. But i come here & people seem to have one every other week (ok exaggeration but you get the idea)? What's the deal?

Thats because all Drives FAIL - ALL of them!  Sooner or later every drive made will fail..

 

I have had some drives last 10 years.. And others that fail while under warranty, So you can RMA them, and then others that have failed just after.. If looking for storage and you need to buy something.. Your best bet is to look for which size is best bang for the buck currently when broken down to $ per GB..   As long as its large enough to meet your current needs.. Buy extra storage that will not be used for years down the road is just wasted $ in the big picture because you paid X  $ per GB today, when we all know for fact that its always going to be X-Y for storage down the road.. 

 

Look for size and speed that fits your need - better to get longer warranty than not but your going to pay for 5 years more than 3 or 1, etc.

 

Looking at the current 3TB seagate I have in my PC, its been on for 4 year and 106 days..  So I would say I have gotten my money out of it.. It will be the next on my list to replace..  I Hitatchi that is 6 years and 284 days and still going.. Its only a 2TB.. sitting in an old pool I use for moving junk stuff too..  Made up of 2 more 2TB disk... This was part of my old nas, that I still have on.. At some point I will retire the older disks out of that pool and replace with larger ones and I cycle smaller disks out of my active storage, etc.  Unless they show signs of failure, etc..

 

Keeping an eye on the smart info can "HOPEFULLY" give you some forewarning of failure.. Not always but doesn't hurt to keep an eye on it.. The scanner software from stablebit can send you emails/text if things found to be be not so kosher with any of your disks, etc.

 

If your using drives for storage and playback of your media.. 5400 RPM is prob fine - As long as it can sustain the speed need to play your movie or music - why would you need more?  If these disks are used for seeking and loading applications you prob want a SSD for that sort of access anyway.

 

Also all my disks are used mostly turned on and stay that way expect for power outages and OS updates, etc.  I think its better for mechanical drives to come up, stay at temp.. Vs the constant on off - so you turn on a disk which is a shock from not spinning to spinning at speed.  It starts to warm up to its operating temp, and then many users shut them off again, just to do the same thing over again the next day.. That disk that is almost 7 years old only has 90 power cycle count..

 

The largest disk I have is a WDC 8TB, which I recently got for FREE from reward points with work and doing steps on health thing.. It was an external WD My Book drive that I shucked to put in my NAS... Which allowed me to move data off a SHR I had setup so I could change it to a raid 0 made up of 3x4TB NAS red drives..   Currently I have it just doing backup duty... But as I move more and more of my library to 4K and higher bitrate 1080 my available storage is starting to shrink... I might have to leverage that 8TB drive as library space if I don't do a bunch of clean up, etc.

 

Seagate I believe wants to release a 20TB disk this year, using HAMR.. I believe... So yeah the much larger disks are around the corner.

Indeed... :D 

That's why the best thing to do is use RAID, or buy two drives, one to use, and another to image to, less chance of failure. Expensive, but data recovery is even more so at upwards of £800+. Better to be safe than sorry :)

 

Drive warranties are great, but just remember they cover ONLY the drive, NOT the data, unless you buy specific data recovery warranty, Seagate offer them with Barracudas, not sure of the others.

I have one of these https://www.amazon.co.uk/Toshiba-P300-7200RPM-SATA-HDWD130UZSVA/dp/B0151KM6F0 (3TB) and I see they now have a 6TB version, when I bought mine it went up to 4TB they are also 7200rpm, because you said you wanted speed.

 

Anyway from researching online the 3TB was pretty reliable but the downside appeared to be noise, which I don't hear anyway in my Dell XPS case. I never hear it spinning up like I remember from my older drives.

 

If you settle on a drive you should google some reviews so you know what you might be in for.

To quote Budman, RAID is not a backup. To quote him again, you need it in 3 places. On your HDD, the cloud, or important data on a USB drive. Or other means.

Thanks for the post. Informative read.

 

I'm interested in this cycling you mention. Do you have a lifespan that you assign to all drives out of interest? You mention drives coming up to being replaced. Something in your head tells you it's time to replace them. Obviously if they've failed then they NEED replacing so that's a given but you seem to replace them before they fail (obviously a wise move) so what makes YOU decide when to replace them?

 

Note: I only put you in capitals & bold because really only you can answer that question, even though someone else might try to answer it for you :)

SMART is your best bet to see if the drive is on it's way out.

Yeah, SMART dat I integrates into Windows and Linux. Think even CrystlDiak does that.

I wouldn't touch the 3TB Seagate drives with a bargepole. The flood era ones were dropping like flies, and even that's an understatement, flies have a longer lifespan. I've had 2TB, 4TB and 1TB Seagates in my server, they're still running great. BackBlaze, who did a review of the failure rates in their datacentres, don't use them any more.

 

https://en.wikipedia.org/wiki/ST3000DM001 - The Seagate 3TB even has its own Wiki page, and not for good reasons. Seagate should have just recalled every single one, and shredded them. Sadly there's still people buying them used, from places like CEX in the UK, who are oblivious and stock loads of them, they even admitted to me under a freedom of information request that they get loads of returns of them (the highest rate of all drives they stock), yet still sell them!!

    • TerraMaster F4-425 Pro review: an octa-core Intel NAS that ships with AI (OpenClaw) by Steven Parker It has been a while since I reviewed a TerraMaster NAS, but the company reached out to me asking if I was willing to test the F4-425 Pro, which goes on sale today. It is an upgrade on the F4-425 Plus, which I reviewed back in October 2025 What you need to know is that it basically follows the design principles of the four-bay F4-425 series, with its all-metal exterior. Here are the most important specifications: TerraMaster F4-425 Pro CPU Intel Core N350 (8x E Cores/Threads, Max burst up to 3.9 GHz) Intel Core N305 (4x E Cores/Threads, Max burst up to 3.8 GHz) TDP: 7W / 9W (Base) Graphics Intel UHD Graphics 32 EUs (1.35 GHz) Intel UHD Graphics 24 EUs (1.25 GHz) Memory 1x slot 16 GB DDR5 4800MT/s non ECC SODIMM (Max 32 GB) 1x slot 8 GB DDR5 4800MT/s non ECC SODIMM (Max 32 GB) Disk Capacity 120 TB (30 TB x 4) Supported RAID Types TRAID, TRAID +, RAID0, RAID1, RAID5, RAID 6, RAID 10 Network 2x RJ-45 5 GbE Internal storage 3x M.2 2280 NVMe Slot (PCIe 3.0 x1) Bootloader 2Gbit 256 GB NAND Flash card (MX30LF2G28AD) USB port (internal) USB Ports 1x Type-C 3.2 Gen 2 (10Gbps) 3x Type-A 3.2 Gen 2 (10Gbps) HDMI 1x (HDMI) Hardware Transcoding Engine H.264, H.265, MPEG-4, VC-1 Maximum resolution: 4K (4096 x 2160); Maximum FPS: 60 Size (H/W/D) 219 x 181 x 150 mm Weight 2.9 kg System Fan 150 x181 x 219 mm Power 90W, 100V - 240V AC, 50/60 Hz, Single frequency Power consumption (HDDs) 45W (4x 4TB ST4000VN008 in read/write state) 14W (4x 4TB ST4000VN008 in hibernation) Noise Level: 20.9 dB(A) Using 4 SATA HDDs/SSDs in standby mode; Test environment noise: 17.3dB(A); Test distance: 1m Warranty 2 Years OS TOS 7.0.0706 (Beta) MSRP £639.99, $699.99, €739.99 / £739.99, $799.99, €839.99 As you can see above, there are two variants of the F4-425 Pro releasing today. The lesser variant has the slightly weaker N305 CPU and iGP, and 8 GB less RAM, although it also costs $100 less than the top variant we are testing today. In addition, these new F4-425 Pros are shipped with the as-yet-unreleased TOS 7 beta. So what is TOS 7 exactly? During the device initialization, you are warned not to use it in a production environment, which we'll get into later. My contact told me that TOS 7 exits beta today, June 23 with version 7.0.0746. The clear difference with the F4-425 Plus is that it contains the more powerful N350 Intel CPU released in the first quarter of 2025, with support for DisplayPort 1.4, HDMI 2.1, LPDDR5 (4800), DDR5 and DDR4, and a max TDP of just 7W. It also supports AV1 decoding, as well as H.264, VP8, VP9, H.265 (8 bit), and H.265 (10 bit). The different capabilities in the Alder Lake-N (and Twin Lake) series are listed below. Processor E-cores L3-cache Turbo clock GPU GPU-clock TDP Intel N355 8 6 MB 3.9 GHz 32 EUs 1.35 GHz 9 W Intel Core 3 N350 3.9 GHz 1.35 GHz 7 W Intel Core i3-N305 3.8 GHz 1.25 GHz 9 W Intel Core i3-N300 3.8 GHz 1.25 GHz Intel N250 4 3.8 GHz 1.25 GHz 6 W Intel Processor N200 3.7 GHz 0.75 GHz Intel N150 3.6 GHz 24 EUs 1 GHz Intel N97 1.2 GHz 12 W Intel Processor N100 3.4 GHz 0.75 GHz 6 W The CPU is part of the Alder Lake-N series that sits just below the top N355 offering, albeit with an impressive TDP (less than the N355 and N305) for the features it offers. It is designed for low- powered systems and entry-level laptops. As before, we are seeing another NAS with an acceptable, if not great, amount of RAM. It should be noted that the F4-425 Pro only has one SODIMM slot, so if you are planning to upgrade the already 16GB included in this NAS, it will have to be on one module of Single Rank DDR5. As a reminder, up until a couple of years ago, it was commonplace to only get 2 or 4GB max on a flagship Synology or QNAP home NAS. Ever since the likes of TerraMaster and more have entered the market with ample RAM sizes included in their NAS offerings, it has gone a long way in forcing the hands of the traditional makers to up their game a bit. Before we dive in, you can view the different SKUs released so far since the 2025 series launched for Home and SMB users, with the most important specifications listed along with the MSRP listed below: SKU CPU Cores Memory Link Price F2-425 Intel N5095 4 4 GB DDR4 2.5 GbE x1 $249.99 F4-425 Intel N5095 4 4 GB DDR4 2.5 GbE x1 $369.99 F2-425 Plus Intel Core N150 4 8 GB DDR5 5 GbE x 2 $399.99 F4-425 Plus Intel Core N150 4 16 GB DDR5 5 GbE x 2 $569.99 F4-425 Pro Intel Core N305 8 8 GB DDR5 5 GbE x 2 $699.99 F4-425 Pro Intel Core N350 8 16 GB DDR5 5 GbE x 2 $799.99 The F2 in the product name means two 3.5-inch HDD bays, where F4 is four 2.5-inch bays. First impressions Like with the F8 SSD Plus packaging, the F4-425 Pro is using the upgraded box materials, which certainly look better than a plain cream colored box with TERRAMASTER stamped on the sides. The box gives off a premium feel and certainly adds a positive vibe to first impressions. In the box F4-425 Pro TNAS device Power adapter LAN cable (CAT 6) Quick guide [full online guide] Limited warranty notice Screws (for HDD bays) Stickers 2x rubber feet (spares) Design As has become kind of common with TerraMaster, certainly in the last three years, the 2025 F2- and F4-series have received a makeover that really adds to the premium feel of the NAS. Gone are the plastic shells, now replaced with an aluminum outer shell, with the front and back retaining the textured black plastic we saw on the 2024 models. Some key differences from the 2024 series include placing the power button back on the front, along with the addition of a Type A USB port. It's not much bigger or heavier either; in fact, it weighs 500 grams less than the F4-424 Pro. It's slightly shorter in height and depth (length), but only by a few millimeters. The front and back do retain a similar style to the 2024 series. On the front, you just have your four bays along with LED indicators for the HDDs and power. The welcomed change is having a USB port on the front for quick access, should you need to back up a USB drive, for example. Around the back, from top to bottom, you have a reset pin hole, an HDMI port, two 5 GbE Ethernet ports, two USB 3.2 Gen 2 (10 Gbps) Type A ports with a Type-C port below them, and a connector for the barrel port power source. Again, there's no Kensington Security Slot present, which is a bit of a shame considering it's a data storage device. Left side Right side On the left and right of the F4-425 Plus, it is completely smooth aluminum with a TERRAMASTER logo printed on both sides. On the bottom, there are some holes to assist ventilation. Unlike with the F4-425 Plus, the rubber feet did come unstuck during the teardown, which was also an issue on the 2023 series. It seems like other customers have lodged complaints about them, as TerraMaster now includes two spare rubber feet in the box, in case any of the preinstalled ones are lost; however, this seems more like a papering over the cracks solution rather than actually fixing the issue with better quality rubber stand-offs. There are also four screws that must be removed in order to access the internals. Teardown Upon removing the four screws, you can slide the device out of its shell to reveal the three NVMe M.2 slots (PCIe 3.0 X1) and single SODIMM slot connector, which is populated with a single 16GB DDR5 4800MT/s module. I added a couple of MP44Q M.2 PCIe 4.0 SSDs (2 x 4TB) that can be availed on Amazon for $492.99 that TEAMGROUP supplied us with, along with a 250GB 970 Evo Plus that my colleague Chris White sent me by accident and let me keep a few years ago. As I have said in previous reviews, TerraMaster support staff actually encourage installing whatever you want on their devices, and happily, the USB port for the bootloader is now easily accessible should you want to use it for your own flavor of NAS OS, such as TrueNAS, Unraid, or maybe Xpenology. Yes, because TerraMaster has now switched to a 256 GB NAND Flash card (3rd photo above) for the TOS bootloader. This is also replaceable, but you can also simply add a USB bootloader, access the BIOS, and tell the F4-425 Pro to boot from that instead of the Flash card. Unlike earlier iterations of TerraMaster NAS, you don't have to tear this down any further than the four screws on the outer shell in order to be able to access and manage the memory, NVMe slots, and USB bootloader. However, if you need to access the NAND Flash card or CMOS battery, then eight more screws (four on each side) need to be removed in order to take off the rear panel with the 120mm fan, and then the motherboard can be lifted off and removed from the SATA connector PCB. There's also no risk of threading the screw holes, because the four that hold the shell in place are metal on metal, while the screws that hold the rear panel on do screw into plastic. Either way, like last time when I reviewed the F4-425 plus, I was just happier to see larger screws being used. Overall, it follows some great improvements in build quality from the 2024 series and earlier. Setup BIOS The F4-425 Pro includes an Aptio BIOS from American Megatrends [1, 2], and you can setup pretty much everything here including the boot order, which is locked to the UEFI OS, however above that choice you can enable or disable booting to the USB bootloader so this would still allow you to switch to a USB stick with an alternative bootloader and boot from it, or disable it to instead always start from the first disk with an OS installed on it. Initial Setup Setup is roughly the same as the F4-425 Plus, along with the new TOS 7 setup dialogs, so there will be no surprises here. Upon connecting to the LAN and booting up, the F4-425 Pro can be reached by navigating to http://tnas.local. If that doesn't work, you can use the local address assigned via DHCP, which you can find using the TNAS PC desktop application, which is essentially a TerraMaster NAS finder. The setup process is pretty straightforward, through a wizard, and in full below: TOS 7 Initialization As you can see, TOS 7 received a new coat of paint, and the initialization requires fewer interactions. Happily, TOS no longer decides to throw all disks into the same Storage Pool; 2.5-inch HDDs are allocated into Storage Pool 1. This is because two of the HDDs are allocated to hold system files. Previously (with TOS 5 and 6), if you pre-installed HDDs and SSDs, they were all placed into Storage Pool 1, even if you did not select the SSDs for inclusion during the onboarding. TOS 7 Setup On first boot, there is a tutorial and some steps to take to harden the TNAS (or not), which includes an immediate update from TOS 7.0.0616 to 7.0.0706, of which the changelog screenshot is also included in the above gallery. It must be noted that the Security Advisor still contains (in my opinion) a pretty major bug in that if you enable SPC and then do the required rebooting, the Security Advisor still says that SPC is disabled. TerraMaster provided the following statement about it: It is disappointing that TOS 7 has been in beta since December, and this OOBE issue is still there. Shutdown option has moved Instead of a Taskbar option to manage the NAS, all of these options have been moved to a "Start panel", initially I didn't see it and my contact had to show me how to power off the F4-425 Pro. To logout, reboot or power off you can find those controls at the top right of the Panel. It is also possible to power off through the TNAS mobile app beta. Storage setup Above, you can see the steps I took to create the Storage Pools and Volumes. I made a second Storage Pool using TRAID on two 4TB MP44Q SSDs (which, in this instance, is similar to RAID 5), and finally, I added the 250GB 970 Evo Plus drive as Hyper Cache on Storage Pool 1 in Balanced mode. Registering If you decide not to lock down the F4-425 Pro in Security Isolation Mode (blocking all external connections), then you could set up a TNAS device ID through the Remote Access setting in the Control Panel (which must be unique). This works in combination with an online TerraMaster account. TOS 7 TNAS Online Creating a TerraMaster account and linking the device online activates the warranty when you provide proof of purchase and the serial number, but it also gives you access through the TNAS mobile app, which allows you to complete certain operationsб including powering off and restarting the NAS remotely. A TNAS mobile update is required to gain access through TOS 7, and this is provided on the TerraMaster website, as it is not yet on Google Play. The app is evolving all the time and has made leaps and bounds since I first started reviewing TerraMaster devices almost three years ago. It is not quite there yet if you are comparing the likes of Synology, which, sadly, a lot of users online do all the time. OpenClaw setup One of the main selling points of the new F4-425 Pro is the inclusion of OpenClaw, with TerraMaster claiming that it is "powered by the world's first AI-native TOS 7 OS, supporting local-first smart workflows and independent data control." However, I immediately ran into problems trying to enable OpenClaw. After waiting 20 minutes at the "Enabling" message of the OpenClaw app following installation, I decided to do some searching online and discovered that it couldn't complete the installation process due to SPC being enabled, which is something TOS 7 immediately recommends to be enabled on first boot. SPC for NAS (TOS 7) is basically the same principle as UAC in Windows; it blocks executables from being launched by non-Super Users. After reaching out to my contact about these issues, I received the following response: Anyway, this only became clear when I closed the OpenClaw app screen and clicked on the OpenClaw icon in the taskbar; that is when I saw the message about disabling SPC. I think, due to the fact that this is a requirement, this should be a prompt during the installation process, not when closing the App Market and then trying to launch OpenClaw. There's also no 'Getting started' guide for people like me who have never used OpenClaw. I tried to add an LLM and discovered the tutorial led nowhere. That's when I started looking around the official TerraMaster forums, and I found a guide that helpfully explains that you won't get anywhere with OpenClaw unless you have a paid plan, which is disappointing because I imagined there would be an option to use a local LLM as I do in SubtitleEdit with Whisper-XXL. In addition, with the marketing imagery on the official site, it says that the OpenClaw feature is "all processed 100% locally for absolute privacy." which led me to believe that I could install a local LLM, not one that required paid tokens. In any case, TerraMaster does not provide guidance for this new feature, which was also a selling point of the F4-425 Pro! My contact also provided clarification about the above points I raised with TerraMaster Since it is not in the scope of the review to add paid services, I'll leave that to the people who are more qualified with OpenClaw. F4-425 Pro Surveillance App TOS also comes with a Surveillance app, which is not installed by default; it can be found in the App Market recommended section. In addition, after installing, it doesn't drop a shortcut on the Desktop or top taskbar, but you can "Send to Desktop" from the App Market listing for the app for a quick way to open it. Adding my Reolink POE doorbell camera was painless. TerraMaster doesn't appear to have a repository of preconfigured cameras; instead, the camera must be added using ONVIF or RTSP. No mobile Surveillance app TerraMaster still doesn't have a dedicated Surveillance app, although from searching online, Surveillance can be used and managed through the TNAS mobile app. I tried this with the updated TNAS mobile app beta in combination with TOS 7 and got a message that Surveillance was "Only accessible through web browser," so I reckon this must be limited to the stable versions of TOS 6 and the mobile app. More quirks In addition, whenever I minimized the Live View window in the browser Surveillance app, the feed appeared to switch to the Low-bandwidth stream, and there was no way to get the High-quality stream back. To get the High-quality stream back, I had to close Live View and then reopen it. Benchmarking A pretty cool feature of the TOS 7 is that it allows you to install directly to the NVMe M.2 SSD. In order to do that, you would have to leave out any HDDs during initialization, and even then, the system partitions are always written to two HDDs when they are eventually added. With three NVMe slots, this also gives an interesting scenario where you could build a TRAID storage Pool for installing all your apps and Docker on, and keep the third for SSD cache on the HDD pool. Limitless options! SATA PCIe 3.0 X1 A CrystalDiskMark test on a mapped network drive from within a Windows 11 25H2 PC (image above) connected over a 5 GbE hub was well within acceptable ranges. Although the read result on SATA was a little less than with the F4-425 Plus, for some reason, while writes were generally better. SATA PCIe 3.0 X1 I also ran the NAS Performance tester, which tests the link speed performance. As you can see, it pretty much maxes out the 5GbE connection. Of course, you can also opt to bond the two 5 GbE connections for a bit more umph, but I didn't do that. TOS 7, which, as of testing, is still in Beta, comes with an App Center that has a bunch of handy programs you can install right off the bat, such as Emby, Plex, Docker, as well as in-house Backup and Surveillance solutions. As you can imagine, any media streaming services you would want to host off the F4-425 Pro will work great, thanks to the Intel Core N350 CPU and its 16 GB of DDR5 memory. Accessing from mobile is only possible if Security Isolation Mode is disabled, which can put your NAS at risk from external sources, so there was no way to access it from the TNAS Mobile app. It's also quiet. I had this sat next to my computer on my work desk for the past week, and I did wonder if the noise I was accustomed to with NAS devices would annoy me, but all I could hear was a soft whirring of the rear fan (which was a little annoying) when the disks were not actively copying or reading data. Conclusion So what have I learned? Unfortunately, this release raises a few important questions and concerns that I feel haven't been adequately addressed. What I didn't like Our variant shipped with TOS 7 beta, and it's advised not to use it in a production environment. I feel that's a bit limiting on an $800 device. The mobile app is also still in beta and does not support some of the first-party apps, like Surveillance, and it still has quite a few bugs. I am a bit confused about the OpenClaw marketing along with the F4-425 Pro. I feel like that if it's going to be a main selling point, then offer official guidance on how to get started with it. TerraMaster recommends enabling SPC, but then markets the NAS for use with OpenClaw, which requires disabling SPC to be able to use it, opening up genuine security concerns for the NAS; and that's before you get into the security concerns of OpenClaw itself. Of course, the above issues won't be a problem if you decide to install something else on it, or even go back to the stable TOS 6. I wish TerraMaster had just given TOS 7 as opt-in rather than shipping with it. TOS 7 has been available as a preview since December 2025 (so well before my last TerraMaster review), and according to a thread on Reddit where a user shared a screenshot from the TerraMaster Facebook page, it is scheduled to launch today, June 23, but there's nothing about that in the TerraMaster news blog. My contact confirmed over email that TOS 7 exits beta today. The rubber feet also deserve a mention as they continue to be a problem, with them coming unstuck the moment you shift the F4-425 Pro anywhere on your desk. What I liked What it comes down to, though, aside from what I already mentioned, you are still getting a quality, affordable device here, so recommending it will depend on the individual's use case. If you're just looking for a relatively small NAS device to manage virtual machines on, backup your files, and take care of your home theater streaming, then it is a great device that will certainly futureproof you for some time. It provides good performance, takes up little space, and is, on the whole, very quiet. Four bays afford proper redundancy using TRAID or RAID 5, and you can even expand on storage capacity by adding the 2-bay D5, or 4-bay D8 Hybrid DAS over a USB 3.2 (10Gbps) link. Considering the 2024 releases were more about power, with the likes of an Intel Core i5-1235U high-end laptop CPU under the hood, I asked my contact last time if we could expect more of the same in higher-end models and was told: It makes a lot of sense to use Intel's N350 chip inside a NAS; it is more than capable of doing what the F4-425 Pro is intended for, media streaming and backup. The only downside is still the clear lack of community and even staff support on the official forums. In the past, I have had topics go unanswered for days, or there would be generic-type "we've noted this and passed it onto our developer team" type responses. Along with the other things I mentioned, it all ends up costing it a couple of points. If you are comfortable with the command line, Docker, and setting up TrueNAS or Unraid, you'll be fine. You can do great things with this hardware. In TOS, the apps are a bit lacking, and things don't always work as expected.\ AI NAS?! What has become clear to me this year is that we are going to start seeing all kinds of "AI NAS" come to market, and while that might be good for us consumers, be diligent and research these claims. Although the F4-425 Pro technically comes with AI, it is really using a cloud service that is externally sourced off-device through the third party OpenClaw app. My colleague did review a newcomer to the NAS space earlier this year, and it includes a local AI assistant inside the Zettlab D4 NAS, and they do not even use AI in the product name, check out Chris' review here. Where to buy and a discount coupon However, it does not change the fact that this is truly a great entry-level home media-class NAS that you can buy right now. TerraMaster is having a 20% off launch discount, plus you can also still apply our unique 10% off coupon on checkout, which only works on the official website.

    • well you can add a GPU for around $500, that's still around the price of Steam Machine but overall significantly better in performance.
