SATA has the ABILITY to transfer more MB/sec than ATA100 or ATA133. However, the only time you NEED that ability is mostly when the HDD is reading from its cache (8MB now days). So you don't use that extra ability very often. Now if you get a SATA 10,000 RPM drive, then the drive can probably use that extra bandwidth when reading as fast as it can. But those drives are very expensive and I don't think you would notice a difference very much.
SATA also has thin cables, so that is cool. It also requires a different power plug, and the adapter doesn't always come w/ the drive. When you first install the OS on the drive, you will needa load some SATA drivers on first so the OS installer will be able to see the drive (which is easy, w/ windows XP you just hit one of the Fkeys and let it load for 10sec and you're done).
