Taip, ypac kai koks Crucial prie SSD dar prideda ir koki Acroni..

 At least the T450s has an empty M.2 slot in case the capacity of the 256 GB, 2.5-inch SSD is exhausted at some point.

Tik speju jis "sharintas" su WWAN .. ir vizualiai koks nors ten 2242 (googlas patvirtino).

<..> while your machine takes the 22x42 form factor (2242).
 
Please have a look at your hardware manual:
http://download.lenovo.com/pccbbs/mobiles_pdf/t450s_hmm_en_sp40g54937.pdf
where manual page 66 describes removal / installation.
 
Then, have a look at the FRU BOM:
http://download.lenovo.com/parts/ThinkPad/t450s_frubom_20150126.pdf
and on the last page you'll see the only factory part listed is the 16GB M.2 2242 SSD normally used for caching (I believe).
 
You should still be able to install a higher capacity 2242 M.2 SSD in that slot, though. <..>
