As of now mfi driver support upto LSI's 6Gb/s Raid controller (Product name= "Thunderblot") "mrsas" driver is a new driver which will support for "Thunderbolt" onwards= product. So plan is mrsas driver is LSI's recommended driver for 6Gb/s onwards Raid = controller. We are also going to provide priority choice for Thunderbolt controller (wh= ich is currently supported in mfi). User can choose "mfi" Driver instead of "mrsas" for Thunderbolt Controller. In summary, mfi will not have any additional support for new controls and i= t will stop at Thunderbolt. In long term, if all user switch to "mrsas" for Thunderbolt card, we can al= so plan to remove support of "Thunderbolt" From "mfi" Hope my response clarifies your doubts. ~ Kashyap >=20 > Sean
