Performance - Raw Drives

Prior to evaluating the performance of the drives in a NAS environment, we wanted to check up on the best-case performance by connecting one of them directly to a SATA 6 Gbps port. Using HD Tune Pro 5.50, we ran a number of tests on a raw drives. The following screenshots present the results for the HGST Deskstar NAS. Corresponding images for similar drives that have been evaluated previously are also provided in the drop-down box for easy comparison.

    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.

    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.

    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".

    I'd like to see http://www.newegg.com/Product/Product.aspx?Item=N8... reviewed

    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.

    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 ;)

    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.

    Anyone interested in HDDs and their reliability should check this article out...
