This was a very simple mod, did not require anything, other then 4 new/shorter screws to replace the ones that were longer on the M4, and a bit of electrical tape. Without hte electrical tape, the drive was undetected, it was shorting out by touching the metal top…so there is a reason to the spacer :).
So far battery life has improved over the 320gb 7200rpm drive the x220 came with. I’d say a good 30 minutes over a usage. The battery still needs a bit of burn in though.

EDIT : Thanks to mark for commenting, you can get these screws :
“The screws are M2X3MM part #10124 from laptopscrews.com.”
