Me personally I have both highend machines. I have a AMD 2100 and a Intel 2.53. Well lets just say the AMD was the biggest waste of money. The machine always runs hotter then intel, intel I have it overclocked to 2900 mhz it just kills my AMD even when its not overclocked. I hate AMD I gave the damn thing to the wife and all she says its not as fast playing games and crap oh well Thats just me, everyone has their own opinon. As for AMD I will never buy one again!

AMD Athlon XP

L1 Cache = 128 KB

L2 Cache = 256 KB

Intel Pentium 4

L1 Cache = 8 KB

L2 Cache = 512 KB

What EXACTLY does the cache in the chip REALLY do? I know more L2 Cache = fast motherfuker and stuff =p

"ooh we managed to dig out this old intel 486 dx 33mhz system and guess what? We pit it against an athlon xp 2200 and it won!"

LOL SOOOOOO True! I sware intel pays off tomshardware cuz i did my own benchmarks on my own athlon XP 2000+ and it was whoopin the P4 2.4 GHZ and fell just shy of the 2.53!! Nice try tom but u can't trick me :)

Thanks for the link.. I understand it a little more in detail, but it doesnt tell about the others like L2 , L3, etc.

Btw, what will be the next owning processor?

Clawhammer/Sledgehammer

or Prescott?

I beleive Prescott will be.. I've barely read anyhting on the new chips.. all I know is that Prescott will have a 200 quad pumped bus (800 mhz bus) and like a 1mb cache.. I hope it doesnt require much voltage.. XTREME OVERCLOCKING BABY!

I have a dual 1800+ amd.. i love it.. i have many other computers.. all amd.. they all beat there comparitive Intel counterparts.. what i mean is same freq.. equals a no no for intel.

Money was not an issue with more. But i still went for AMD. WHy? because i belive that supporting AMD will keep the competition running and having intel keep on pumping out faster cpus. Tell me. If there was no competition agianst intel or maybe agianst AMD. would they release new cpu's? We would still be stuck at around 533mhz which is i think about the time intel got some seriers competiton. please forgive me with spelling. i want to sleep yet i can't pass up the oppurtunity to throw in my opionion. btw... the next batch of systems i build will be Intel. Why? because its fun. Its not really about wow i can run Quake 3 2fps or even 10fps faster. Its about how i actully fragged you. Its not that i can complete a Seti@home work unit in 3hours. Its that i can have Seti@home dedicated.

I remember when i used to put down intel at every change i could get. Its not possible anymore. When my friends ask me what they should get i ask them, what are they going to do with the system. I mean .. just simple stuff.. heck go for an iMac :p

But in all terms i would go with AMD currently. Maybe a 1800+ or something with 1 gig of ram. GeForce4 4600 and Epox 83KA+ or something like that.. can't remember exact model number. And a nice lian li case.

true dat, heh

Most amd users have probably built their own computers.. not saying Intel users can't build. Just saying that i see a more majoirty of users that use AMD having built their computer and a more majority of users who use intel having purchased from Dell and the likes.

Majority

Mojo

heh looks funny

Not really man, I'm a power user and I'm experienced, and I use Intel. But I use it b/c for me its more reliable and I got it for a good price too, but if AMD's could fix their heat issues (b/c I don't want having a loud ass HSF jus to cool it, and cuz it makes my whole room hotter than it is) then I would consider getting an AMD system for my self but since its not fixed yet, and I had to many problems with it I jus dropped the idea of having AMD and went with Intel again.

With all the talk of a few extra 3d marks, pcmarks, fps whatever; you seem to have neglected other important issues (for me anyway) such as stabilty, noise levels etc.

I have to admit to never even seeing an AMD chip in action so I'm not going to pass comment on which I think is better, but I've used a P4 machine running at 2.2GHz and it was virtually silent.

I suppose it doesn't really matter if all you're gonna be doing is playing games, but for a PC I'd rather work on, it would need to be silent.

I won't bring my G4 chip and it's silent operation into it ;)

Since when do CPUs make noise? :ponder:

Just get a good fan.. I have an AMD XP 1.53Ghz and an Intel P4 1.8Ghz, they both use nice and quite fans.. no noise factor. FYI... both chips are nice and stable... I am not sure which is better for overclocking though.

Lol, you know what I meant. The PC I was using was a stock compaq one so the cooling was the bog standard crap they put in. I opened the case and it was a tiny fan not worthy of anything.

But it done the job, I'm wondering would the same fan be as useful on an AMD chip? Of all the people I've talked to who own AMD and Intel (including reading this thread), it' that the general consensus is that Intel chips operate at a lower temp, therefore not requiring the sound of a 747 taking off every time you start your PC...

OK, so AMD has heat issues...not a big deal. In my mind the reason the AMD is hotter is because it's actually doing more work. The Intel chips do a pretty good job but they stay cooler cuz they do less work. That's just how i see it. I've built about 4 AMD system and 1 Intel system because the person was brainwashed by those commercials. Now they wish they had gone AMD cuz they come over and use my computer and mine is much faster (According to him) than his 1.8GHz P4. I guess it's all just the quality of the components you use when building any system but i went AMD at a t-bird 750Mhz and never went back to Intel after coming from a P3 866mhz. The AMD was faster using the same components except MOBO and Processor.

Don't tell me i'm wrong cuz of my opinion. I don't think you guys are wrong either. But so many different people can't be wrong about AMDs being good tho. Maybe an AMD 2200+ doesn't beat an 2.53Ghz Northwood but hey, they aren't in the same class so you can't compare them. One is .18 and one is .13 (which is another reason it runs cooler).

Oh and about the fans, skrew all all.. hehe, i like fans they are soothing! I can't sleep without a fan so these case fans add to the purr in my room.

hehe.. :)

Nicely said man. I went P4 there for a while after my tbird 1.4 blew then i decided to give AMD another go (sold p4 to my brother) and man was i glad i did that! This thing runs great! :)

no, both CPUs produce the same amount of watts, its just a lot of people build custom AMD systems and use a cheaper heatsink and poor case airflow, you cant cool a cpu good when your case temp is in the 40Cs

unless you are that one guy here who magically has a P4 running at 21C and a case temp at 36C

Ok, that's cool. It's just that reading this thread, someone like me who doesn't build PC's would think different.

I'm seeing temps all over the net of like 20-30 on P4's and temps of 30-60 on AMD's.

oh the temperature that is reported is lower in the P4s, but they dont run as high as the Athlons either, P4s top out around 50C and Athlons at 60C, so its all with the numbers

    • 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.
