I would have spent more to have drives that dont run so hot and as well require firmware updates!
21 February 2015
Summary: Pros - Good price Cons - 5 year old drives (2010), run very hot, make a lot of buzzing, require firmware updated (note that firmware updates are available from companies that used these drives - but not able to install, as the installer identifies that my machine is not the correct brand)
Summary: It makes a horrid sound and read/writes at about 60mb/s. Had to format it myself which took about an hour or two. (Two terabytes is a lot to format). Sounds like someone rolling around on a creaky bed. I'm afraid it's going to snap the actuator arm in half or something, it's so loud. My friend said to not buy Hitachi and I see now why it was so cheap...
Hard drive portion is fine, but BEWARE THE SATA HEADER.

Summary: Drive is exactly what I expected. Fast, 100ish megabyte a second read and since it is a hitachi drive, it will be very reliable. However, the sata port is very cheaply built. When installing the drive, the sata cable moved a bit, and the sata header snapped right off. I ended up soldering the cable directly to the hard drive, but it still is a bad solution. I really wish I could give this drive a better review, but I can't because of the terrible sata header.
Summary: Unit was described as "new" and "OEM Pull". Well, the OEM pull part is true. The drive I got in August 2014 was made in October 2010. The "new" part - not so true. S.M.A.R.T. data show 28,465 hours of use and 79 power cycles. It looks like this drive was pulled from a data center or server where it was used 24/7 for the last 4 years. Two stars because the unit is, for the moment, working perfectly.
Summary: The drive listed is a Hitachi HUA (Hitachi Ultra Star) disk drive. That's a high cost "Enterprise rated" disk drive. There is a very similar part with a HDS prefix (Hitachi Desk Star). The Ultra Star is designed for 24/7 server use. The Desk Star (HDS722020ALA330) is designed for desktop use with far fewer hours per year on power. If you pay for the HUA, make sure that's what you get.
Summary: I'm not saying it's a bad thing, in fact the one drive I tested so far seems to work BUT it was not mentioned anywhere in the product description that those were refurbished drive, or at least not clear enough that I could see it when reading the title and product description. I thought I was buying new drives and having a very good deal.
Summary: EDIT - 06.23.2014: The following review was obviously intended for *a seller of the product (Green Tech) and *not the product. At the time of purchase, the UltraStar line of Hitachi HDD's was still considered reliable by the purchaser. A proper *product review would have given this particular item Four stars ****. _________________________________________________________ Western Digital now owns the Hitachi manufacturing rights.
Don't expect the best and plan on paying out of you own pocket to ship back defective products.

Summary: I bought two of the 1TB drives. One had date of FEB-2014 while the other was from SEP-2011. The SEP-2011 one was also the drive that showed up with a circuit board part almost falling off. So I filed return claim with amazon and when it was approved found out I had to pay to ship it back even though they were the ones who shipped me a defective product. The one drive is working well so far but I will not be buying from this supplier again.
