I bought an msata also and planned on just putting the os on it but then it hit me the hm77 can only have 2x 6g and was a mild blow..newegg shipment of the msata got lost so I just put operating on my raid0..i would bet im not sure tho that only the 2 ports for the 2.5 hds are capable of sata3 and the msata and the dvd port is sata 2 ...I don't know what use I have of the msata maybe ill install windows on it just to see if it will do sata3....the 2 samsungs in raid zero are nice only regret is I didn't get 2x 240 or 256.. heres a vid of my system booting
icouldnt find cams usb so used my camera I know it sucks
