We are a clinical firm that were very excited to get your HD SATA III to upgrade our servers, but our IT department was shocked to see the way the parcel was delivered and the packaging that you used to protect such sensitive devices- even baby toys are better rapped. Even if you are offering a return [policy and a warranty that comes with it, the data that are at risk and that was transferred to the hard drives are no recoverable- without paying double the price for the hard drive itself. Unfortunately this is was a great loss to us as we can’t send you the defected parts for replacement but, as they contain extremely confidential files for which the slightest possibility of data recovery from another agency would be considered a breach of Health Privacy Act. Still we are very dissatisfied with your merchandise and the way that it was sent to us.
2 of the HD stalled within around 30 min of data transfer. Our servers are i7 and all have SATA III ports.
I know about luck, but I don't believe in it, especially in business.
If you think of using this dealer again, think three times.

Packaging was grossly neglected. The disk failed within a few minutes during the installation of the OS. It started to make noises and then was simply not recognized by the BIOS during boot-up process.
I had to have Western Digital send a new unit, still waiting for the new part.

I purchased this drive to provide me with additional storage capacity on my Drobo backup system. Unfortunately, the drive was defective. But, without hesitation, Amazon sent me a replacement drive and made arrangements for me to ship the defective drive back to them without cost. This is why I buy with confidence from Amazon. The new drive is functioning fine and exactly meeting my backup storage needs. Good product. Good price. Great service.

By D. Berube TOP 500 REVIEWER on Sept. 6 2012
What can I say, it's a 2TB drive that works out to 1.81TB of usable space once formatted, writes about 30-40MB a second in my Nexstar HX enclosure (via USB 2.0), runs plenty cool enough (though this is helped by the fan in the enclosure) and it's covered by a 2 year warranty, unlike comparable Seagate/Samsung drives which come with a 1 year warranty. In other words, I'm more than happy with this hard drive and I have no problem recommending the Green series of hard drive to anyone looking for economical storage space.

I upgraded my TiVo using this hard drive. For starters, the drive is very quiet. My TiVo is in my bedroom so this was extremely important to me. I don't hear it at all, and the TiVo is located 10 feet from my bed and I've got excellent hearing. I found the drive very easy to install in my TiVo. After booting into Linux and running the copy program, expanding, and then super-sized the drive - all was 100% OK. I went from having 15 hours of HD space left, to 231 hours of HD space. When issuing the commands to make the drive quiet and save the settings, none of those parameters worked. However, this is not the fault of the drive, and it seems to run fine without having run these commands.
