Lenovo Thinkpad T440 M 2 Slot
Lenovo Thinkpad T440 M 2 Slot Rating: 4,2/5 574 reviews
OK, before I buy one of these, I want to be sure I know what I'm getting into. I looked at the user manual] and found several notes about the M.2/NGFF drive slots. It has two, in addition to a 2.5' drive bay. But... when I read the manual, it says:RAM: Both the ThinkPad T440 and the ThinkPad T440s support up to 12GB of RAM. One memory slot can house up to an 8GB module, and there is also 4GB soldered onto the motherboard. The low end T440 doesn’t have on-board memory, relying solely on the memory slot. As most T440s owners probably know, there is 3rd M.2 slot available in our little machines underneath internal battery. But first few notes regarding this: - my T440s came with 256GB Samsung SSD and no SmartCard reader, so space under battery is completely empty. Because of that, I needed two additional parts: LENOVO Cable NGFF, PartNo: 04X3987.

My question is... why all of these caveats? Is there some sort of technical reason I couldn't or shouldn't use an M.2 drive as a bootable drive? Why have an extra slot then? Why would it be 'unreliable'?
Could someone with some expertise about this sort of drive and/or Lenovo weigh in here? I understand that NGFF drives are new, expensive and at this point are often used for caching, but I'd guess that over time capacities will expand, and it would be nice to be able to upgrade down the road and move my boot/system drive over to a new SSD. But I'm not going to buy something that I can't upgrade.OK, before I buy one of these, I want to be sure I know what I'm getting into.
