  2. X240 M.2 Slot (Under Battery) Hiya:) I read online that in some X240s (usually the ones with a standard, none SSD drive) that Lenovo installed a 3rd M.2 slot for a small cache drive.
Hi guys,

Some: Single-sided M.2 SSD, via M.2 card slot, exclusive with Smart card reader Some: Double-sided M.2 SSD, via M.2 card slot, exclusive with WWAN card Widescreen.

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.
