What petery83 said...think it's a given. Now a WD Raptor 10K rpm sata will make a diff.
I used the adaptor and eventually bagged it because the little ah heck kept cutting out
sometimes. Think vibration from case fans loosened it. Maybe if I'ld taped it on it would
of been OK. Due to that I didn't care much for it. Maybe plug it into a optical drive just to
get some use out of it.
