HGST/Hitachi (HUA723020ALA641) Ultrastar 7K3000 2TB 64MB 7200RPM 3.5 (Enterprise Grade) SATA III 6.0Gb/s Hard Drive

I do not have one of these specific drives. However, I have 4 Hitachi Ultrastar SATA II HDDs of 750-to-1,000 Gb capacity, which have withstood 5 years of near 24/7 use in ordinary non-RAID applications. As far as I can tell, the drives have all been golden. I am shopping now for a couple more of them for this reason. While my data and programs are not critical, they represent many hours of work that would have to be redone if the existing drives failed, hence I use them for backup functions, mostly. However, I would not hesitate to use them for any role. They are and sufficiently fast for me; near-perfect all-around drives. The SATA II interface is actually faster than the stock SATA I on my old-but-good ASUS mobos (P6T, P5WD2-E Premium), which are good enough that I have no plans to replace them soon. With or without a SATA II/III upgrade card, these HDDs will operate fast enough since I am neither a gamer nor excessively impatient. I rarely feel as though Im waiting for my PCs to do something. Booting up, and loading PhotoShop are about it. Everything else happens pretty darn fast. Thats technical for very quickly. I hope my experience helps someone. Im sold on Hitachi Enterprise drives.

Running 10 of these in security system server and have been running almost 24/7 for 2 years and no failures! I install these now in all my cliends servers, great for NAS servers.

Ridiculously annoying noise. I RMAd it and the replacement had exactly the same sound.

I purchased four of these to put in my Vantec HX4R raid enclosure in raid10 mode, giving me a total of 4TB. Put them through rigorous smartctl + badblock testing following the advice here (minus installing FreeNas): https://forums.freenas.org/index.php?threads/how-to-hard-drive-burn-in-testing.21451/ Not a single error, took around 40 hrs to test one drive. On USB3 I am getting around 230MB/s transfer speef. Would highly recommend these drives.

works wonders, faster bigger, easy to use. more then i expected

As advertised, shipped fast, arrived OK.

If you are building on a budget, avoid these drives! It worked fine for about a month then failed. Luckily it lasted enough totransfer the data to a WD drive. Will never buy low cost, high capacity drives again! IF YOU WILL BE STORING IMPORTANT DATA ON A DRIVE, DONT GO CHEAP

Great price, installed two of these in a NAS. Working with no issues now for several months

I actually ordered two of these hard drives. One did not perform as expected. It was returned for a full refund. The second has performed flawlessly thus far. Specs and reputation of these drives are outstanding. The price is fantastic

So far, this has been an amazing drive! Will update if anything changes!
