What is the difference in the different flavors of SATA drives?

There is only 2 different types of sata, SATA and SATA II. SATA is capable of transfer speeds of 1.5 g/s where as SATA II is capable of 3 g/s which if you can do that insane math is theroetically twice as fast. Is that what you are asking or are you asking about SATA raid?

keep in mind that while sata II is theoretically tiwce as fast, so far, Raptors on SATA I (i dont believe that a sata II raptor exits yet) have had the fastest access and write times.

Yeah, so far there isn't a hard drive on the market that can saturate the SATA II bus.

yea but some get close as I have a SATAII drive that can do a burst speed of around 250MB/s with the SATAII standard having a max burst speed of 300MB/s (SATA at 150MB/s and normal hard drives (ATA UltraDMA 6) at 133MB/s) That hard drive is a 400GB Seagate Barracuda 7200.10 ST3400620AS average read:65.0MB/s random access:14.2ms. Compare that to a WD Rapter 36GB with about 120MB/s burst speed, average read:57.2MB/s, and random access:8.5ms.
