I hate having to reinstall everything, but if it will make a significant improvment in boot and load times, I will consider it.
I don't think you'll see a significant boost in performance when changing from a 7200RPM 8MB buffer PATA to a 7200RPM 8MB buffer SATA drive. The interface doesn't make that much of a difference. It you plan on getting a 16MB buffer or a 10000RPM SATA things could change for the better. The 16 MB buffer helps once you booted windows, for the boot time it doesn't make much difference. A 10000RPM raptor (or 2x in raid0 like rickbrook) would really make a difference in boot times, loading, everything.
