up at the top left-hand corner of AS SSD it will show the driver.. like IaStor... or MAhcsi... ect.
This will tell the truth as to what the board is using.
I will humor the Sata II and III topic..... IF your MB came with different cables.. they will have stamped on them as such. Some manufacturers take advantage of ill-knowledge and attempt to keep the belief alive that there is a difference.
In fact here is a quote from Crucials forums on such a topic by user 'dingle'
"I just tested with my c300 and x58a UD7 with SATA 3.0 and 2.0 (at least it doesn't say 3.0) cables in a SATA 3 port, and both work and perform the same it would appear."
