Converting X201 to SSD - Need FRU 42W8019, 42W7888, or compatible alternative - Thinkpads Forum
X201, I think from about 2010 or 2011. It's a little slow, but with the ssd, 8gb ram (instead of 4) and running Linux Mint, it sure isn't bad for a 10+
Inside the x201 there are 2 of these ports, one of which used by the WiFi card. Is it possible to use the second for an ssd? : r/thinkpad
