Summary: I had two of this in my Synology NAS. The first drive started having error after 6 months and it was replaced by warranty, then the 2nd one died just 2 months after the warranty expired. I only use WD HDD and I only had bad experience with the so call “Green Drive”. I bought another newer version of the WD green for a single drive NAS and it also failed after a year and was replaced by warranty, very unreliable and it’s totally not worth trying.
Summary: The 2TB Western Digital Caviar Green disks are perhaps the worst disks that have ever been produced. I purchased 4 of these disks for my NAS box and all 4 of the disks failed. And each time a disk would fail I would return it under warranty and receive a new disk. And two of these new disks failed. From my perspective this was the worst batch of disks that have ever been produced anywhere, anytime. Avoid them at all cost.
Summary: I purchased two of these for my new system and was thoroughly disappointed. The first drive failed within six months, and the other failed just after two years. I have tried many different hard drive manufacturers over the years, and have seen little difference in reliability among the "top" manufacturers, despite what the exceptional advertising from these companies will tell you.
Summary: Installed just a few days ago with fresh install of Windows. BIOS is no longer recognizing the drive. When I installed into antoher computer, same issue. When installed as a USB drive, it immediately causes computers to crash as soon as drivers load. Not good.
Summary: This is an update to the review below. After my review below, the company worked VERY hard to make me happy by not only sending me a new drive, but also upgrading the drive from the WD Green Label equivalent to the WD Black Label equivalent (WD2001FASS). So, I have to give them kudos for customer service. However, I ordered the drive in April of 2010 and it has now failed in February of 2011.
These drives are horribly unreliable, dying after 4 months

Summary: I know this is labeled as having no-frill packaging...but I almost had a heart attack when I opened the tiny box and saw only an invoice and small piece of blister pack inside. This box was probably whacked on the floor all through shipping with the drive ping-ponging around in the box...I'm amazed the drive even powered up, but I returned it out of fear of future failure. The HD itself is fine, but Amazon gets negative 3 stars for the horrible packaging. Geez!
Summary: I have a total of seven of these drives. Two have failed within the first month of use, after I spent days migrating all of my data over to these new high-capacity drives. Both were connected externally via eSATA (externally rather than internally), but this may not necessarily be relevant because a cursory Google search on this issue led me to complaints by numerous other users who also have experienced failures with these drives.
