This hard drive works well enough, but has a controller considered less reliable than most, and is relatively slow. I would suggest spending a little more and getting a Crucial (somewhat faster and great reliability), or spending less on one of the better chinese cheap drives (similar performance and reliability).
my desktop went from booting in 20 minutes to around 30 seconds....if you need a faster machine and you don't want a new one...sometimes it's the quickest most efficient thing to do...and with this one it's good value.
