Hitachi GST Ultrastar 7K4000 4TB SATA II HDD Review

Article Index

















ultrastar 7k4000a

   We all know (or at least most of us) that hard disk drives are much slower than solid state drives and so using the second just to house the primary OS (operating system) is always the ideal scenario. However no one can deny the splendid price/capacity ratio of HDDs especially now that we even have massive 4TB units available. Personally i don't feel I’ll ever be happy at least not until we finally see drives with capacities well exceeding the 10TB mark but in the meantime they highest available capacities will just have to do. A couple of months ago we checked the latest consumer oriented Deskstar 7K4000 4TB SATA III hard disk drive by Hitachi GST and as promised back then today on our test bench we have the latest enterprise class Ultrastar 7K4000 4TB SATA II hard disk drive.


   HGST, a Western Digital company, is a market leader in enterprise hard disk drives and develops advanced hard disk drives, enterprise-class solid state drives, and external storage solutions and services that are used by large and sophisticated technology companies to store, preserve and manage data.

HGST maintains its U.S. headquarters in San Jose, California and is marketed under the HGST brand name.


   Many of you are certain to think that i made a typo error when writing the title of this review but that's not the case not and so today we will be taking a look at the SATA II variant of the Ultrastar 7K4000 4TB line. Now i can't really say why (perhaps SATA III is not 100% backwards compatible) but Hitachi GST offers the same exact drive in both SATA II and III flavors so we thought this would be the excellent opportunity to test both variants to accurately measure any differences in performance (testing the same exact drive in SATA II and SATA III versions with the same system is as good as it gets) although in the following benchmarks you will see that there's virtually no (or very little) performance difference between the Ultrastar 7K4000 4TB SATA II and our previously reviewed SATA III drives. So time to get up close and personal with the Ultrastar 7K4000 4TB SATA II HDD and see what kind of performance you can expect from it (aside its massive 4TB capacity).

Kinjo you do realize that the website you pointed at has no real experience with all those models right? They just compare specs, that's all.
If you want a 4TB drive for a NAS (network attached storage) get an Ironwolf drive (even a RED WD drive would be ok), or a SkyHawk one if you want to place it in a NVR (network video recorder).
If you want a 4TB drive to Store data and leave it be (not use it every day) get the lowest-cost model you can find, it should do fine for such use.
If you want a 4TB drive to use on a daily basis then get something better, no need to say a specific model but Seagate has a complete range and yes the Barracuda/Pro lines are very good.
Bottom line don't read websites that have nothing to do with storage media other than comparing specifications.

Kinjo if only things were that easy....The fastest drives right now are made by Seagate but HGST comes really close and Toshiba follows....The problem is with durability and that is a matter of luck, you may get a Seagate that will last you 10 years or you may get one that will last 1 month.....Same with the other manufacturers......

:cheer: SATAII is enough for HDD. SATAII can offer more than the highest speed that HDD would have. But the cost for SATAII and SATAIII seems not sharply different. At least it is on SSD. May be hitachi could use SATAIII as a sale point. it is not a bad ideal.

Yes i know, it seems that the SATA II versions are more "special" and "focused" for specific clients so i doubt they are even sold in the market that's why they don't even mention it (had to adjust the specifications sheet to include the SATA II variant, it doesn't by default).

Interestingly enough their website only shows they have a SATA III version :blink:. Nevertheless a great looking review and a great product. I have two 1TB Hitachis, a Deskstar 5K1000.B and a Deskstar 5K1000.C and both have been great drives.
