i bought a hd from this website back in march and haven't had a problem with it at all.. they were the cheapest drives i could find with a decent speed. I'm no computer geek so i don't know how they compare to the more expensive models, but it works just fine for me, i use it for pictures and video that i take... i keep the music on the main hd since i have a laptop so i can always have my music.

they have other brands, thats just the brand that i bought.
