Summary: I bought this 500GB drive last year of June or maybe July (I gotta check) and still kicking to date! Only to find out that 500GB wasn't enough! :) I got this for my first PC build that I'm using right now to write this review. It's a really great drive.
Summary: Added this as a second drive, the "green" spin up feature saves energy which is fine since this is a second drive in the machine for backups, video, etc. The spin up is very fast and not noticeable when used as a second drive; not sure how this would behave as a primary drive.
Pros: Low power and SO QUIET! I haven't really pushed it to any performance extreme, but after installing Windows 7 MC on it and watching HDTV with Windows Media Center, this HDD hasn't given me any problems.
