I can't find it on the BOM for the T440p, but for the T440s, I have FRU 04X3827, which is a 16GB SSD on a M.2 adapter that plugs into a connector in the T440s main board, and the middle connector in your photo looks like the corresponding one. When you think of notebooks with two storage drives, you probably imagine a bulky 17-inch system you can barely carry. However, a number of lightweight laptops, including the 14-inch, 3.6-pound.
I got a few questions regarding upgrade of my X240. I learnt that X240 has 2 slots for M.2 SSD. One is occupied by a 16GB SSD cache drive (this is what I find in my device manager) and the other is for WIFI card. I wanna replace the 16G SSD with a new SSD as windows drive, keep the HDD and upgrade to 8GB ram as 16GB is not supported.
My questions are:
1. Is it any 2242 m.2 SSD with be OK? Which model is crecommended? 128GB or 256GB?
2. Some said the slot is for cache drive only. Is it really OK use it for windows drive?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:

M.2 solid-state drive as a bootable device. The M.2 solid-state drive is used for “cache” function and to
support the Intel Rapid Start Technology.

andrecommended to use the M.2 solid-state drive as a bootable device. The M.2 solid-state drive is designed
and developed for the “cache” function purpose only. If you use the M.2 solid-state drive as a bootable
device, its reliability is not guaranteed.
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'?
