Hi, I have question. Do I need a ssd adapter, or something if I wanna add 7 mm ssd, to 9,5 mm hdd place? Also I wanna ask do I need to install firmware update, or something: http://www.dell.com/support/home/US/en/04/Drivers/DriversDetails?driverId=W8P67&fileId=3290054826&os... . What to do if my laptop not boot? I'm planing to buy 850 evo, or something from crucial. Which is better? Heard some people say that mlc memory is more reliable than tlc (evo 850, mx300) so maybe go for mx200 with older mlc memory?
