2 HD's with the same exact specs, but one is SATA and one is EIDE....how much faster/better is SATA? Never used SATA, so I'm just curious cuz i might get me a MOBO with SATA.. thanks!
There is pretty much zero difference. The limiting factor is the drive mechanics (and firmware), not the interfaces connecting it to the computer.
SATA is overall a neater solution, that's all. It has thinner cables and you don't need to fiddle with master/slave jumper crap either. It's simply a more "high-tech" solution in general.
