HGST Ultrastar HE10 | HUH721010AL5200 | 0F27352 | 10TB 7200 RPM SAS 12.0GB/S 256MB Cache 3.5 Inch | Instant Secure Erase | 512E | Helium Platform Enterprise Internal Bare Hard Disk Drive

Running 10 of these HGST Ultrastar HE10 drives and have not had any issues. I have successfully been able to preclear each drive which verifies every bit is readable and writable. After filling them with data the drives still operate as expected. I have not run them at full SAS speeds and have not needed any warranty service in the first year of operation. I will be purchasing more and recommend them to anyone wanting to build a large array of dependable drives.

Worked perfectly first try. I have a mini-SAS controller in my computer, so no problems whatsoever. Know this brand is consistently rated as highly reliable - check out Back Blazes blog, they are a data backup company and release stats every quarter on drive performance, using many different brands.

Random reads could use some work, I dont think the read-ahead cache was very well thought out. The value for the drive is quite good though and after multiple tests as well as filling/depleting the drive multiple times, there have been no issues. Its not a quiet drive btw - pretty much all the hitachi sas drives make a bit more racket than some of their peers. Just something to keep in mind for those looking for a media center drive.

maybe it was the shipping but I have bought 26 of these and so far 4 of them ar dead and I have only tried half of them. Even the working ones are audible when they spin up.

Very fast and easy to install. Working flawlessly right now.

The spin of the drive is acceptable but every ~5 seconds the drive will produce a clicking noise with a strong vibration. Its disappointing that online sellers are doing this to take advantage of customers and trying to get away with it. I have to pay local taxes and shipping fees to return this.

We installed 24 of these in a hadoop cluster and they are working flawlessly.

It shows 9 TB when linked to a card. It worked well. I used it wish LSI 9362-8i card. it is as fast as SSD as a single drive. Good, quiet.

Excellent drive, massive capacity, cool running. No warranty with HGST, though, so be aware of that when purchasing the drives from third party sellers.

The HUH721010AL5200 model is an SAS drive, and will NOT WORK on a computer as a SATA drive. The SAS plugs are a uniblock that look like the SATA and Power plugs have been fused together, with the central gap filled in by pin connectors on the flip side. You need an SAS controller also, not just the cables. Silly me, I thought all hard disc drives used SATA or SCSI controllers. I guess SAS is the new SCSI (SAS= Serial Attached SCSI). Theres something new every day. Yes, there is a tiny description under the listing for this hard disc drive that says SAS - 7200 - 256 MB Buffer. Needs to be in big bold letters, in the title of this listing. The SAS standard has been around since 2004, but seems to have been mainly in use with large storage systems, and I had never seen a hard disk drive being sold in a consumer retail environment with this sort of connection. SATA models of the He filled 10TB HGST are the HUH721010ALE600, HUH721010ALE601, and HUH721010ALE604
