I was just wondering ..... A single samsung evo ssd in one of the 5,1 drive bays gives about 250mb/sec. If you use the osx raid utility to stripe drives in the bays, say 2 in 2 bays, or 3 in 3 bays , or 4 in all 4 bays , what are the speed improvements ?? I assume you dont get 2x 3x 4x the speed , but what do you get ? I imagine you are limited by the single? raid controller. I am using an ssd blade as a boot drive, but this raid would make one possible video editing option.
