I just bought a new Mac Pro 6-core and an OWC 120Gb SSD drive. My question is putting the SSD on optical drive bay or Hard disk drive bay, is there any difference in performance? My understanding from my old PC is never to share the SATA cable with the optical drive as it will take the transfer speed of the optical drive, because they are running in the same "channel"? Is the 2 SATA cable in the optical drive bay 2 separate distinct ports/channel? Is putting the SSD on the hard disk bay better as it will run faster? Thanks.
