I'm looking at buying an SSD for my newest build, but I've run into some problems. I want the drive to be SATA, but the only affordable ones of decent size are IDE. Will the fact that it's an SSD be fast enough to compensate? Also, about size. The SSD will only hold the OS. How much HD space is needed for Vista. I know it says you only need like 15 GB or something, but how much room would I need to have to make space for things like program installs? Thanks.
