HGST Deskstar NAS 6 TB Reviewby Ganesh T S on December 23, 2014 11:00 AM EST
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.

Guspaz - Tuesday, December 23, 2014 - link$300 for a 6TB drive doesn't seem very cost-effective when 8TB drives sell for $260, and 4TB drives sell for $140. Heck, even the 4TB HGST DeskStar NAS sells for only $165. This isn't really a fault with the HGST drive specifically (since other 6TB drives aren't any cheaper), but more a fault with the 6TB capacity point.
Of course, the 8TB drive in question is using SMR, and so ought to be rather slow for writes, but when you've got a bunch of them in a server with some SSDs for caching, it shouldn't be so bad.
insz - Tuesday, December 23, 2014 - linkCan you please provide a link to an 8TB drive for $260?
Dreamwalker - Tuesday, December 23, 2014 - linkHere in EU you can get the Seagate Archive 8TB for ~226EUR (275USD with vat). It targets cloud/cold storage market but I think it should be great for a HTPC too...
patrioteagle07 - Tuesday, January 6, 2015 - linkYou do not want that drive... it is cheap because it is SMR. SMR is for COLD storage not NAS.
BeAi - Wednesday, January 7, 2015 - linkHi there, we are Premium Reseller of HGST, about these disks i could give some more inputs... First, the Seagate is a SMR Disk, only good for Backupszenarios, further they have only 3 years warranty.
The HGST 8TB Disk is not a SMR Disk, HGST has got the 10 TB SMR Disk for Backupsolutions. Than the HGST Disk have got 5 Years warranty, for business solutions is that an argument. Last but not least, HGST has released on all SAS3 Disk the Media Caching Technologie, the disk are probably up to 3 times faster than other disk on the market. We have tested disks in our Lab, with a 1.2TB media caching 10k Disk, it will be faster than a 15k normal 2,5 inc disk. For more information, feel free to visit our online Shop: shop.storagespace.ch Kind Regards.
BeAi - Wednesday, January 7, 2015 - linkSorry i have forget that the HGST 8TB also have the Helium 8 Technologie, its also a He8 Plate, the Seagate havent got helium inside...
Benefit of HGST Helium: up to 50% less energy cost, and less heat from the plate... If you wanna have an offer or more informations: firstname.lastname@example.org
takeshi7 - Tuesday, December 23, 2014 - linkI think he's citing this article. That $260/8TB is bulk pricing for buying 20 drives it looks like.
nandnandnand - Tuesday, December 23, 2014 - linkThe $260 8 TB drive isn't out yet. But it is a good thing
realwarder - Friday, December 26, 2014 - linkHaving a higher performance 6TB drive now is worth the extra money in the time saved over upgrading a 4TB drive later. It may be twice the price, but in $ it's not really much compared to reworking an entire setup later to add storage (unless you have a 8+ disk array with lots of room to grow)
hlmcompany - Tuesday, December 23, 2014 - linkRegardless of the capacity, this HGST drive is in the same category as a WD Red Pro, NOT a WD Red.
