I have 10 dell latitude XT2 model to resell..problem is the micro SATA HDD it came with are not working...so i have one hack..either get a msata ssd with a micro sata hdd adapter......then again, it does have a wwan slot that is empty...can i use a m.2 in that slot or will it be a mSATA? which one is a better option? Also if you could enlighten me with the various form factors and pins and notches of M.2...Thank you in advance
