Hi everyone!
My son is upgrading his work laptop from a T440p to a T470 and is tossing the T440p to me, (see, if ya raise them right.... ).
I'm planning a few mods, (my son is a dev, but left the machine 'stock'), mainly the screen and touchpad. I also want to upgrade the drive to either a 128gb M.2 with a 1 TB drive for data in the main HDD slot, or 128 2.5 SSD and swap out the CD/DVD for a caddy to hold the 1 TB drive.
I've been looking at the specs and I can't find any information on the M.2 speeds for a SSD. Is it better to get a regular 2.5 SSD for this machine or will the M.2 provide faster throughput? Theoretically, the M.2 should

be faster, but as I said, I can't find any details.
Thanks!
