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

Fast.

works well

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

Ive had this drive for slightly less than two years and it completely failed today. It was fine when it was working, always a bit louder than my other platter drive, but seemed alright. Im pretty unhappy with its longevity, though. Will definitely not be buying Hitachi again.

I was building a custom computer for friend of mine and He needs a lot of storage, so I found this drive on amazon for $50. Made by hitachi it says enterprise drive, 64MB of cache and everything. Hard Drive arrived via USPS and it was well secured. the read & write speed is amazing. I got 145mb/s read & write, so that was amazing. Overall the hard drive works like it suppose to, but it does make a lot of noise. I was concerned about this issue, so i run Western Digital extensive Hard Drive test to make sure the drive was working ok and after running the test for 8hrs it didnt find any problem. Ive also checked for bad sectors and again didnt find anything. I know some of the drives does tend to make these type of noises such as some of the older Seagate Drives. I am giving 4 stars because of the noise otherwise the HDD is doing the job like it suppose to.

BackBlaze recently compared their server records on Hitachi, WD and Seagate. Hitachi beat out WD as the most reliable drive by a small but significant margin. Hitachi is also fast, though I dont have figures. Their quality control is still considered good in an industry prone to outsourcing its manufacturing. Seagate trailed a distant third in reliability. I researched before buying. I bought and installed four of these 2TB units in a single RAID 10 configuration, last month, through Amazon. The drives run 24/7 and are constantly accessed by me and a file synch program. For my money theyre as silent as any others I have used in Mac or PC installations, barely audible 2 away on my work desk. This RAID is really fast. I read the comments about head repositioning noise. It is a slightly noticeable curiosity I wouldt have identified without these reviews. I hear it only once in a while, but I dont find it distracting or objectionable. However this supplier is not Prime, and the time lag between order and delivery dates is of some concern. I ordered two more on Saturday and they still show as Preparing for Shipment Monday night. I may order bare drives from NewEgg when I need them to complete a project.

Dont know at this time only had 30 days.

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

I needed this really bad. Im glad I could get one this quickly and it functioning a lot better than my other one.

Because I didnt have any problems with the seller and the HDD is cheap, it receives 4 stars. Its pretty fast for a 7200RPM drive, i think its reliable, but my only complaint is that its really loud. When things write or get read from the drive, the drive vibrates like crazy. I replaced it with a Seagate HHSD and that drive is much quieter. Online I read that Hitachi holds the reputation for being the most reliable drive, so I keep this Hitachi as my system backup drive. If you dont care for the sound though, this is a great drive.
