I have a 5,1 MacPro with 2 x 1Tb HD drives in Bays 1 and 2. Bay 1 has OSX and Bay 2 has Win 7 (set up via bootcamp). I am considering buying 2 SSDs (probably Samsung ones) and then cloning my OSX drive to one and my Win7 to the other. Effectively replicating exactly what I have currently only onto SSDs. I would then run everything on the SSDs and keep the 2 HD drives as backups/storage. Would I have any problems with this? Should I keep the SSDs in drive bays 3 and 4 or use pcie, say 2 of the Apricorn Solo x2 cards? Apart from the speed boost is there anything else to be aware of? Lastly, what sort of boot time is possible with these two methods?
