Stunning ! ... really, I'm blown away. Samsung EVO 750 (or any SSD) screws onto the card, this takes 2 minutes. It receives power direct from the card, no cables. Install in PCI slot, another 2 minutes. Instantly recognised by the MP ( 10.8.5 installed previously ) Boot time from "chime" 15 seconds !! VERY impressed, so simple and fast, full SATA III 6GB/s connection. Bought from Expansys yesterday afternoon and delivered this morning at 9am. I would recommend this to any 3,1 / 4,1 / 5,1 MP owner.
