Hi. I've just been asked to build a PC for a friend. I've suggested Gigabyte ga-77-d3h with i5 CPU (same as mine!) and want use SSD for W7. It seems obvious to use the mSATA slot for eg Crucial M4 256gb as boot drive freeing up a HDD slot rather than using separate standard SSD. Is this ok or is this slot intended for use only as fast cache (it says it uses Intel Smart Response Technology). I'm ok on the build but NOT a technical wizard! Thanks for any help.
