This is my third 2TB green drive (which the "mainstream" drives are, once you take them out of the box) and all of them have been phenomenal. After suffering through multiple failures from other brands, I've made it a point to only buy WD drives when I'm purchasing for myself (to clarify, I mean that when work buys me drives, I can't help if they buy me a Seagate that fails in a year, but if I have a say in the purchase, I only buy WD.) I bought this drive to go into an external enclosure that won't support any sizes higher than 2TB, so I was limited on my size choices. Unusually, the store did not have any of these on the shelf - plenty in the back, just none on the shelf - so I had to find a salesman to help me track them down.
I have one of these drives as a primary on my home media server as well and it performs flawlessly. The drive itself is about 3-4 years old and it's not so much as hiccuped. I can have 4-5 simultaneous streams running off the server and it never has an issue.
Bottom line: if you're in the market to get a hard drive, you can't go wrong with Western Digital. If you need a drive for storage or streaming, and heat/noise are concerns for you, or simply cost, this drive is a great option.
