A:Answer Fortunately I am using a new ASUS board with all 12 channels SATA 3, if you have a older board with only SATA 2 connectors you are not getting the 6gb/s band width. Some boards come with a combination of SATA 2 and 3 they will be different color plugs, and usually be near the top of the board, dark blue I think. If you only have SATA 2 connectors, don't waste money on SSD drives, use faster access time drives and set them for a RAID 0 . noisier but fast.
