I'm going to be getting another hard drive for my computer around Christmas time, and I'm kinda split as to what I want. It's between a 10k rpm 36.7 gig raptor, or a SATA 2.0 160 gig. I know the raptor will be faster, but what kind of speed increase will I be seeing? I currently have just a Seagate SATA 160 gig hard drive with about 55 gigs left. It's not like I'm in need of a lot of storage space, but it's always nice to have a lot of space if you need it, so that's the reason why I'm torn between the two.
