I reordered a 13" i5 with Apples 128GB SSD. My plan is to put that drive into the optical bay and put the C300 in the Sata III position. Problem is, newegg will take it back with no restocking fee as long as I don't open the box. I paid $200 last week for it when it was on sale. It seems like people are having real good luck getting the Intel 320 to work and no issues. I'd love to keep the Crucial if I positively knew it would work. From what I've been reading, the 256GB C300 has been more of a problem than the 128GB. Looking for some advise.........
