SATA 6.0 Gb/s capable hard drives are still within the range of 3.0 Gb/s speeds. A RAID-0 array of two hard drives will theoretically double performance.
SATA 6.0 Gb/s hard drives haven't even reached their maximum potential. The Velociraptor 10k SATA 6.0 Gb/s 600GB HDD($300+) from WD doesn't even reach the maximum speeds of 3.0 Gb/s.
Also, depending on the mobo, you might run into a problem I had where, once I'd installed the "faster" WD drive I couldn't run the slower secondary drives on the same SATA controller. I had to buy a dedicated card to run my backup drives which really sucked. Just rebuilt and went all raid. Never looked back.
Im either conisdering a WD 1TB caviar black with sata 3 or 2x500gb for raid 0. Which one is better?

lol i c u kinda took my advice :P anyway i suggest u get the 1tb becuase yea sure the speed isnt there but in a raid ur pretty much screwed if even the slightest problem happens cause the data is literally split in half and placed on the drives. and u can't use one without the other, UNLESS u have a 1tb or 500 gb external to back up ur data.everyday, i wouldnt do the raid (well i did but yea.)
Actually, 1TB+, the newer ones not first generation ones, perform extremely well over smaller sized hard drives. These 1TB+ HDDs even perform the same, and in a few rare cases faster than WD's new VelociRaptor 6.0 Gb/s 10K HDDs.
