HGST Deskstar NAS 4 TB Review
by Ganesh T S on November 22, 2014 2:00 PM ESTSingle Client Access - DAS Benchmarks
The HGST Deskstar NAS was connected to a 6 Gbps SATA port off the PCH in our DAS testbed. After formatting in NTFS, it was subject to our DAS test suite. The results are presented in the graphs below.
In general, we see that the HGST Deskstar NAS manages to beat out the contenders with lower rotational speeds (such as the 5900 rpm Seagate NAS HDD and the 5400 rpm WD Red). However, it loses out to the higher end drives (such as the WD Red Pro or the Seagate Enterprise Capacity v4 - which has extra cache). This performance difference is also brought out in the pricing that we looked at in the previous section.
Certain workloads seem to make the HGST Deskstar NAS perform well in the PCMark 8 storage bench, but, in general, we see the scenario from our robocopy benchmarks play out here too.

According to WD, the Red Pro is rated at 1 in 10^15 not 10^14 before URE. Are you working from some other data or is your comparison chart inaccurate? Planning on purchasing several drives in the next few weeks and that was going to be the key factor in my decision.ganeshts - Sunday, November 23, 2014 - link
Thanks for bringing this to my attention.When the WD Red Pro was launched, the datasheet had URE < 10 in 10^15, which I had denoted as 1 in 10^14 in our initial review. Backed up by a third-party post on another forum here: http://www.techpowerup.com/forums/threads/western-...
It looks like WD has fixed this 'error' in their latest datasheet. I will update the table shortly.

I do remember that from their launch now that you mention it. Still torn about my purchase.Julian Boolean - Saturday, December 5, 2015 - link
Fact : As of Today (Dec 5th 2015) the Western Digital Spec Sheet for The Red Pro STILL lists the URE rate as 10 in 10^15. It is not "a mistake in the specs sheet". It has been listed that way since product launch and has never been corrected. 1 in 10^14 = 10 in 10^15. This is a 1 in 10^14 drive. I called WD myself to confirm this. Three days later I got the answer I suspected all along. It IS 10 in 10^15 ( which equals 1 in 10^14). This is just clever marketing, and it irks me to no end that countless review sites such as this have incorrectly listed the URE rates.I cannot tell you how many review sites have made the mistake of listing it as 1 in 10^15.

Read throughly the backblaze report on reliability of hard-disks, as pointed out above. HGST (former hitachi) build very robust hard disks, and they deal with vibration pretty good. Thats one of the factors (not sure if mentioned in the article) that the NAS deskstar incorporates,and which could be rated as "enterprise only".Mikemk - Sunday, November 23, 2014 - link

7200rpm? Sorry but as far as I'm concerned, that's not a NAS drive. Nope nope nope nope and nope. Too hot, too noisy, silly - just silly design choice.Daiz - Sunday, November 23, 2014 - link
hmm, you might want to tell the likes of HP about that since they let you stuff their NAS appliances with up to 15k RPM drives. Not all NAS appliances sit in your living room ;)MikeMurphy - Sunday, November 23, 2014 - link
Reliability of HDDs has become a huge problem. I bought this drive as it's apparently the most reliable consumer mechanical drive out there. I was hoping there would be some commentary on this.NoSoMo - Monday, November 24, 2014 - link
