[Vincent Becquiot] “but I can safely assume that the OS should use the fastest drive”
Alot of people waste money on very fast large drives for the OS/Apps, but once booted and program is loaded there is very little use for the OS drive except housekeeping, usually a good use for a newer PATA drive thats laying around or been in use in a system thats being upgraded, use a single or raid SATA II for capture and video source files, another SATA drive for scratch disks, previews, audio, finished clips
