Above I had said USB 3 and should have said Sata 3 for the SSD's, Crucial is using Sata 3, it has about 9 models out with I Sata 3 from Micron. SSD's do reduce the startup load time where faster Hd's do not, raid 0 will not which for me brings up questions without answers.
Good luck with your next rig.
