M.2 is a solid-state drive (SSD) form factor primarily used as an operating system boot solution. Lenovo ThinkSystem servers support M.2 drives either with the addition of a supported M.2 adapter or module, or directly on the system board. So I was doing a clean install of Windows on my Lenovo x250. It has a 16gb SSD M.2 'Cache' drive and a standard 500gb main drive. Unfortunately I selected the M2 drive as the installation path and formatted the other drive. So I have Windows on the smaller SSD which is now the 'C' drive. Nice table but I would've sorted it by generation instead of separating T and X. Notes on T450s (might also apply to T450): The 'Single-sided M.2 SSD, via M.2 card slot' is actually the cache drive under the battery and not one on the WWAN slot.

Under the bottom cover you can get access to the following internal components:
– Hard drive

– Internal battery
– Heat sink and Cooling Fan

The laptop comes with a 16GB 2242 M.2 SSD. My new M.2 2242 is Transcend MTS400 SATA3 M.2 SSD. By the way, Plextor M6G is also compatible the Lenovo ThinkPad X250.

Remove the screw and take the SSD out of its slot.

3. Upgrade the hard drive and 2.5″ SSD

The laptop comes with a Seagate 500GB 7200RPM, and you can upgrade to a larger capacity hard drive, or replace it with a 2.5″ SSD.

In my case, I replace it with a 2.5″ Samsung 850 EVO 250 GB SSD.

4. Upgrade the RAM

The Lenovo ThinkPad X250 comes with an 8GB DDR3L-1600MHz RAM. It has to meet my daily needs, so I did not upgrade the memory, but a user has been upgraded to 16GB, and can be used normally, please see this thread from Lenovo forum.
