X1 Carbon Gen3 upgrade to 1TB SSD

[PiT2]

Hello,

is there any vendor lock in BIOS to M.2 SSDs in X1 Carbon Gen3 notebooks?

I've a 20BS003NXS Thinkpad with 512GB SSD which became insufficient. (ThinkPad X1 Carbon 3 i7-5500U(3.0GHz) 8GB 512GB SSD 14.0" WQHD TOUCH)

I need to upgrade to 960GB/1TB SSD and my question is - will work any M.2 SSD with correct length of 80mm?

E.g. INTEL SSD 540s Series 1TB M.2 22x80mm which (as it seems) is currently the only 1TB M.2 available in my country?

The newer X1 Carbons do not have the touch screen feature.   

I too would like up upgrade to a 1TB internal drive.  But I can't figure out if I can or not.  

Why does Lenovo screw up the design?  They used to have an SD reader built into the first Gen X1 - that was great.  But they took it away for the 2nd and subsequent gens. 

The 2nd had a stupid keyboard change.   Who runs this project anyway?

3rd was good with the Touch and new keyboard (like the old one - you know - where everyone is already familiar with it for a decade?)  

The 4th - NO TOUCH!  And still no SD reader.
