Thanks for that info ibmthink.
The tabook doesn't specify the M.2 SSD physical size (42mm):
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
But it is specific about the HDD slot:
Some: SSD / SATA 6.0Gb/s, 2.5" wide, 7mm high, removable, upgradable
Some: HDD / SATA 6.0Gb/s, 2.5" wide, 7mm or 9.5mm high, removable,
upgradable, Shock Mounted Hard Drive, Active Protection System
Confirming ibmthink's info.

The biggest capacity for 2242 form factor is 256GB for now.
The best m.2 ssd 42mm is the SP900 adata 256GB which writes and reads above 500mb/s
The SC or the super boot ssd from my diggital are very slow. They write it writes up to 400mb/s, but on the factory site producing them is written 140mb/s
Personally I have never reached more than 136MB/s write on that SC and SB drives. So get the Adata one.

Old thread but thought I would post. I have installed a 1TB HDD into my x240 (and x250) and it works just fine. Probably going to upgrade to the 2TB drive soon (digital pictures, sheesh...).
I also have a 256GB M2 42mm drive where I store movies to watch. Drive is super fast and plays back movies just fine.

Yup. the M.2 drive is a second drive. I believe some people have configured it as their primary drive, but I just didn't want to futz with it and figure out how to do a full windows install from backup media to the M.2 drive. I just cloned my original 500GB drive to the 2TB drive and put all the extra space into my "data" partition. The M.2 drive is just another "drive" that I use to store media (movies)
