I know this could look a little odd coming from me (HDDFreak), but when I build my new system, how much of a performance increase would i find by upgrading to a cheap-ish SATA drive instead of using an old 7200rpm P-ATA one? I'm wondering as I would rather buy a hard-drive later rather than sooner as I don't store much data on my computer that I would be grumpy losing. Any thoughts or answers would be appreciated.
