I have an early 17" MacBook Pro 2011 model which has SATA III main bay and SATA II optical bay. I would like to setup them up with SSD's as raid 0 (my first raid setup). From what I understand going raid 0 is basically combining them as one hard drive doulbing the speed (i.e. 500MB/s + 500MB/s = 1000MB/s). Would it be possible to mix and match? Would I be able to use (2) SATA III SSD's and presumable get 1.7x the speed instead of double (i.e. 500MB/s + 250MB/s = 1000MB/s)? OR would this result in kicking back BOTH bays to SATA II speeds? In addition, if its the 1.7x case, could you use a SATA II SSD in the optical bay and SATA III SSD in the main bay or do you have to use both the same SATA speed for raid 0 to work? Sorry for the lengthy question, but I tried to keep it short and simple. TIA!
