Shasoosh Posted May 18, 2015 Share Posted May 18, 2015 I returned a faulty 3TB Barracude and got a new one recently (ST3000DM001) I'm trying to figure out why this drive is so slow. (Read is really slow) Here are my results: From reading online I should be getting something close to this: I've tried different sata cables, different sata ports, different power cables, etc'. The drive is on AHCI mode. Should I try anything else or is that another fault drive? Thanks, Link to comment Share on other sites More sharing options...
+PeterUK MVC Posted May 19, 2015 MVC Share Posted May 19, 2015 You really need to test with the drive empty which is how the online one was tested. The more you fill the drive the slower it gets for mechanical reasons but I don't think it should be that slow. Are you overclocking? Link to comment Share on other sites More sharing options...
Shasoosh Posted May 19, 2015 Author Share Posted May 19, 2015 Thanks for the reply. Nothing on my system is overclocked. Emptying the drive, I guess, will be my last resort. It never consistent. Sometimes it takes me a minute to extract a rar archive with a 8 gigs file in it. Other times the same archive would take up to 4 minutes. In both cases there is no other activity in the background on the drive from another software. Link to comment Share on other sites More sharing options...
+BudMan MVC Posted May 19, 2015 MVC Share Posted May 19, 2015 "The more you fill the drive the slower it gets for mechanical reasons" Where did you pick up that little nugget of FUD? He is not talking SSD.. Benchmarking shouldn't care if the disk is full or not.. Now can overall performance of the machine if you run your OS disk at 99% full.. ok, is it going to be fragged to all hell at that state most likely.. Shouldn't run your disks at 100% capacity no - but I doubt he is, it shouldn't make that sort of difference on his benchmarks that is for sure. So here is my ST3000DM001, it is not full, but it sure is not empty either and getting better speeds than what you showed you should get. What does the smart show for the disk, you mention sata but what speed I, II or III? Grab https://stablebit.com/Scanner they have a 30 day trial and you can get the smart info, details of the connection, etc. etc. Lets see what that shows... What is the controller on your MB, etc. Can you post up the details of your machine. Clearly something not quite right there.. Disk is possible of much better speeds. Also this is a refurb as well. Thee was a bug in some of their firmware that was constantly parking the heads.. You could see that in the smart info the LCC was out of this world when the drive was less than a year old.. I contacted them about it and they replaced it without issue. Have you grabbed their tools and ran a diag on it? Link to comment Share on other sites More sharing options...

That only comes into play when you are close to capacity Link to comment Share on other sites More sharing options...
Tomo Posted May 19, 2015 Share Posted May 19, 2015 Try testing it outside of Windows with a boot disk and in another computer, could be a driver issue or a controller issue dropping down to a lower speed. Link to comment Share on other sites More sharing options...
Shasoosh Posted May 19, 2015 Author Share Posted May 19, 2015 Let me know if any more info is needed. I didn't mention but I'm dual botting that drive. Windows 7 and Yosemie Link to comment Share on other sites More sharing options...
Noir Angel Posted May 19, 2015 Share Posted May 19, 2015 I have that exact same drive and I got these results (My drive has about 1.5 TB of data on it so emptying the drive shouldn't make any difference). It's definitely way slower than it should be, I'd advise initiating another RMA. Write speeds being so far above read speeds is very abnormal.

+BudMan MVC Posted May 19, 2015 MVC Share Posted May 19, 2015 looks pretty normal - curious why you don't show supporting ncq? And what is your MB or controller card, curious why you show rev 3 vs 3.1 for sata? Not up to speed differences with 3 and 3.1 - I know 3.2 is out But I don't think that should account for the low speeds your seeing. So you mention dual booting - do you see same low speeds in other OS. Have you booted live CD and tested speed? As mentioned installing RST sure wouldn't make it slower - do you have that installed or no? Link to comment Share on other sites More sharing options...
Shasoosh Posted May 19, 2015 Author Share Posted May 19, 2015 No idea about the ncq. I noticed that our models aren't 100% identical (1ER166 VS 1E6166 ) maybe that got something to do with that? My signature contains all my specs. My MB is a Gigabyte H87-D3H. I'll do some testing on Yosemie and with a live cd when I'm home. The results are with RST installed. Tried to uninstall it but that didn't change anything. Here are some more tests: Because CrystalDiskMark results seemed off and inconsistent I've run that test again. Once on version 4 and once on version 3. The results on version 3 are completely different: Link to comment Share on other sites More sharing options...

Aergan Posted May 19, 2015 Share Posted May 19, 2015 Try a different drive that you can find some reference benchmarks for? Could well be a firmware or SATA controller compatibility issue. Tried a different SATA data cable? Link to comment Share on other sites More sharing options...
Shasoosh Posted May 19, 2015 Author Share Posted May 19, 2015 Other drives working great. The same drive worked fine until recently.. Here are 2 tests one after the other. If I'm reading this correctly the drive gets really slow on 3 places. Is that enough proof to get that drive replaced? Link to comment Share on other sites More sharing options...
Arkos Reed Posted May 19, 2015 Share Posted May 19, 2015 ST3000DM001 ? Backup all your data ASAP and dump them, they ALL fail sooner or later. I've had so many die on me at work that our reseller replaced them without asking for the failed ones to be returned. I'm using them as shooting targets now.

Noir Angel Posted May 19, 2015 Share Posted May 19, 2015 The CPU usage in your HDTune benchmark is oddly high, it shouldn't normally go above 5%. My drive for comparison. Slightly different firmware number but the same drive. Link to comment Share on other sites More sharing options...
+BudMan MVC Posted May 19, 2015 MVC Share Posted May 19, 2015 "they ALL fail sooner or later" Agreed since ALL drives fail sooner or later.. Saying that this specific drive fails so much that its not worth using is nonsense.. Agreed something is not right there.. I was pretty happy with the support I got when I was seeing the high number of LCC.. Open a ticket with the info you have and see what they say. I would assume they will want you to run their diag tools, etc. That cpu use is really high.. Something is not right.. your other test 57MB is really low number.. So that kind of says not a OS issue.. Do you have a buddies machine you can put it in for benchmarking? Link to comment Share on other sites More sharing options...
Shasoosh Posted May 19, 2015 Author Share Posted May 19, 2015 Ok, some findings. I recently installed a new firewall called Windows 10 Firewall Control . For some reason when that was installed a proccess called LMS.exe (Intel related) was eating up CPU more than it should. After removing the firewall I run another HD Tune test. The CPU usage is now low but the drops are still there and the drive is sill slow when moving files \ extracting files. Budman, I'm not sure to what test you're referring with 57MB.. Maybe the Crystal one? Also, I couldn't find anywhere a place to open seagate a support ticket. Do you mind pointing me to the right direction?

Shasoosh Posted May 21, 2015 Author Share Posted May 21, 2015 Thanks BudMan, I've opened a ticket and will update on the results. I formatted the drive. Here are the before and after tests. What does it teach me? I have no idea. Getting the drive half full can degrade its speed so tremendously? Never happened to me before. Should I still RMA it? One thing I do know for sure is that the OS X partition wasn't the problem because it is still present on the drive. Link to comment Share on other sites More sharing options...
Shasoosh Posted May 22, 2015 Author Share Posted May 22, 2015 I copied my drive 800 gigs of data and run another test. I don't know if the drive is inconsistent or the tests are not that accurate. Link to comment Share on other sites More sharing options...
Odom Member Posted May 22, 2015 Member Share Posted May 22, 2015 You will always have a difference in the benchmarks. They will not give you the same values every time you run it. Link to comment Share on other sites More sharing options...

Getting the drive full doesn't degrade it's performance that much, mine has about 1.5 TB of data on it and it still behaves fine. Screenshot the stuff on HDTune's "Health" tab, sometimes the SMART parameters can help reveal what is wrong. Link to comment Share on other sites More sharing options...
