In Desktop Internal Hard Drives

This HDD has plenty of capacity for my security cameras. I switched from a 4TB to a 14TB and now I have months of video storage!

I am using this as my primary genomic dataset decompression/analysis/recompression drive. It replaced the competitor’s highest-end consumer-grade performance hard drive, which also has a five year warranty. Sustained writes of 170MB/s are amongst the highest I’ve seen from a single (mechanical/platter-based) hard drive. For comparison, the drive it replaced topped out at 150MB/s according to my testing. This Seagate drive also has slightly lower latencies than the drive it replaced. At idle it pulls a few watts less than the drive it replaced. Finally, it is noticeably quieter (though in an enterprise setting this is irrelevant).

I remember it coming fast, it is quiet and is still kicking after all this time.

Works fine

Big enough to store all my stuff with room to spare.

Got this computer up and running with this hard drive - got it for another computer and than the hard drive crashed on this one ( IT WAS A mediamax ) just quit !!

The 6 TB version seemed like the best balance between price, size, performance and noise / heat. This is going in a 4 bay NVR which is in a very quiet environment. So far, these drives seem much quieter than the 7200rpm version (during seek) which are being swapped out 1 at a time to allow the RAID rebuilds to catch up. Temps are 10C lower than the 7200 pro version. (37C vs. 47-49C per SMART data.)

SPEED! I tested file transfer speeds with this drive copying to-and-from a RAID0 of four 1TB Western Digital Black 64MB cache drives (all on SATA3 controllers). Initially a large file copy from RAID0 to this drive will burst up to about 450 MB/s and then slowly drop down to around 190 MB/s sustained. I also benchmarked this drive with 'HD Tach RW' benchmarking software on both SATA2 and SATA3 controllers for comparison. HD Tach SATA3 (6.0Gbps) - 340 MB/s Burst Speed - 210.7 MB/s Average Read - 194.9 MB/s Average Write - 9.1ms Random Access (Latency) HD Tach SATA2 (3.0Gbps) - 214.8 MB/s Burst - 174.0 MB/s Average Read - 155.2 MB/s Average Write - 9.2ms Random Access (Latency) Clearly this drive performs best on a SATA3 controller and maxes out a SATA2 controller. This is incredibly impressive for a single disk drive. The drive did not have a "sloping" HD Tach graph where the beginning performs faster than the end of the platters, as many do.

perfect for NAS. I don't really need the AI function in the drives they sit in a UNIFI protect set up. I have the 24TB one in my home protect set up and initially it was loud, but it has become more quite since it finished it originally set up. I have 8 of the 8TB drives with no issues. 2 are cold spares. when they go in I'll order 2 more. I take the drives that are out of warranty and typically put them in our 3rd tier backup NAS systems and they seem to live forever. Technically out of "service life" but that doesn't mean I take them offline, I stick them into a lower use environment to live out their days storing old accounting stuff. Nothing as exciting as VIDEO

What a few models can make in performance difference. When comparing the new ST4000VX007 performance compare to an older version ST4000DM000 you can see a big performance difference considering the main specifications are identical. You then compare those specs to a Western Digital 7200RPM hard drive which is even more amazing that the performance is almost on par with hard drive models that are just reaching the 3 year mark in age. For the testing I used CrystalDiskMark on a Windows 10 x64 system. Seagate ST4000VX007 (5900 RPM, 64M Cache) -------------------------------------------------------------- Sequential Read : 176.826 MB/s Sequential Write : 172.492 MB/s Random Read 512KB : 53.898 MB/s Random Write 512KB : 90.506 MB/s Random Read 4KB (QD=1) : 0.600 MB/s [ 146.4 IOPS] Random Write 4KB (QD=1) : 1.508 MB/s [ 368.1 IOPS] Random Read 4KB (QD=32) : 1.666 MB/s [ 406.6 IOPS] Random Write 4KB (QD=32) : 1.509 MB/s [ 368.4 IOPS] WD1003FZEX (7200 RPM, 64M Cache) ---------------------------------------------------- Sequential Read : 202.486 MB/s Sequential Write : 197.416 MB/s Random Read 512KB : 65.774 MB/s Random Write 512KB : 121.537 MB/s Random Read 4KB (QD=1) : 0.724 MB/s [ 176.9 IOPS] Random Write 4KB (QD=1) : 2.096 MB/s [ 511.7 IOPS] Random Read 4KB (QD=32) : 1.893 MB/s [ 462.2 IOPS] Random Write 4KB (QD=32) : 2.063 MB/s [ 503.6 IOPS] Seagate ST4000DM000 (5900 RPM, 64M Cache) ----------------------------------------------------------------- Sequential Read : 143.287 MB/s Sequential Write : 129.919 MB/s Random Read 512KB : 35.893 MB/s Random Write 512KB : 65.565 MB/s Random Read 4KB (QD=1) : 0.365 MB/s [ 89.0 IOPS] Random Write 4KB (QD=1) : 0.938 MB/s [ 229.0 IOPS] Random Read 4KB (QD=32) : 0.870 MB/s [ 212.5 IOPS] Random Write 4KB (QD=32) : 0.890 MB/s [ 217.3 IOPS] What these results tell us is that the ST4000VX007 has almost double the performance of its ancestors and is almost on par with 7200 RPM drivers dated the same time period as it ancestors. It would have been nice to compare it with a 7200RPM drive of made recently but I do not have any around to compare it to.

Great added space, easy install, put in one remirror, put in second remirror, then expand boundary and you're set. Easy, just don't call tech support, do not let them screw it up. update 04/13/2017 running since 12/26/2015 24 x 7 am buying more.

a very reliable hard drive. I've been working with these for years and I've never had one fail on me yet. I've got a few previous generation models and they've been running flawlessly for 4 years now.

Good performance for 7200 RPM drives Mostly silent operation Running 24/7 in RAID 1 without issues Good value at 350USD each (you may find a different price) CMR technology, 5-year warranty

-Quiet -Runs cool -Works perfectly in Synology NASes (both 4- & 5-bay) -Large

it smells like a hard drive it looks like a hard drive it's quiet but it kinda sounds like a hard drive it's a hard drive
