I bought this a few months ago for my new build, i've never had one before, My god i don't know why!! This little thing is great, i put all my computer together, plugged it into a SATA 3 port on my Asus Maximus Extreme-z and booted... It was the only thing on my build that i was worried about, and again i don't know why... It worked like a charm, my computer picked it up instantly and istalled windows 7 so incredibly fast. I really do recommend this SSD due to researching into some others and they have to use lunix to update the firmware which just looks like hassle. I haven't had a single problem and even tho it's nearly full it runs as fast as it was with just the OS. Getting a second one soon ^^ Well worth the money!!
