Didn't last very long, but the price was right

Summary: I'd recommend it as long as the price was quite good. Expect to replace it in 5 years or under.
Pros: Appropriate packaging, arrived promptly. Easy to install and worked well with linux tools. Performed well as part of a RAID-1 array until it died.
Cons: I bought this to be part of a RAID-1 array on linux/ubuntu on 2011-05-30, and it died on 2015-12-14, so i got 4 years 6.5 months out of it. Not a very long lifetime for a hard disk, since I expect 5 years minimum.
Summary: BEWARE that the "2-year warranty" is not valid (at least not through WD). I received the drives this week and installed them in a NAS. Everything works fine. However, when I registered the serial numbers on Western Digital's web portal, I was informed that they are "out of warranty".
Cons: It's a ok drive. It hasn't failed me for over a year, with constant storage. I use it for storing big files. Movies, software etc. Lately (month or so) it's been laggy. I'm only about 900ish gigs used. About 900 gigs free. And all my movies are lagging. It keeps trying to scan the drive. HD proba...
Pros: An update to my 12/5/13 review below: WD invited me to their support site, which told me that my failed drive had a THREE-year warranty, not just two. I sent it in, and the company shipped me a 2TB version of a newer model of Caviar Green. It passed all the relevant tests in SeaTools. Thanks, WD!
Summary: I always make sure my drives have sufficient cooling to stay below 40 C since that helps to improve longevity, but that doesn't seem like enough for this drive. I don't enable spin down on drives since thermal cycling is generally bad for reliability so the drive only has 38 spindle start/stop...
Pros: It has lasted almost 2 years and decided to start its death process with a couple months left on the warranty and didn't die completely yet so I was able to retrieve all data off of the drive.
Cons: I'm getting "disk failure is imminent" warning in Ubuntu which says the drive has been powered on for 1.2 years and the temperature is currently 36 C.
Summary: Kudos to WD for a reasonable warranty and also the advance replacement program (they send you a replacement before you send in the old drive, so you can tranfer data off). lets see how it goes. Will update review.
Pros: reliable for most of the drive's lifetime, was a good deal
Cons: Drive started failing during boot process. Diagnostics show nothing amiss but drive goes missing in BIOS intermittently (causing Windows boot failure). luckily barely within warranty; filed an RMA
Summary: RMA was relatively quick but WD is changing their website so it was frustrating as I received no confirmations, no answers to my emails. But the RMA'd drives just showed up about two weeks later.
Pros: Cool, quiet, cheap.
Cons: Two out of four died in a year. With WD shortening the warranty to 2 years I won't buy these any more.
Summary: I took a chance when I bought three of these drives a little over a year ago. There were a number of comments that described what seemed to be about a 25% failure rate. There were enough positive experiences that I decided that the low price ($80) after rebates was more then worth the risk.
Pros: (1) Relatively low cost drive at the time of purchase (January/Feb 2011) (2) Large 2TB size (3) Easy install and setup with Windows Home Server (4) Fairly fast read speed, good for storing music and videos to be streamed over a home network (5) Newegg shipping was fast.
Cons: (1) The chances of failure after about a year seem fairly common from the comments I've read here. (2) Low cost of drive may not be the best choice for a server.
Summary: This drive failed well within a year but Western Digital where excellent in terms of replacement service everything.(Much better than Seagate) I have found though that all these terrabyte++ drives seem to fail fairly quickly.
