And most of the laptops that have an M2 may also still have an open
real sata location (maybe even with a cable) that you could also put a
sata ssd or spinning disk in, and dual boot that way. The 2 most
recent ones I have opened that came with a M2 both had a location but
only one had the correct cable for power and sata.
The Dell G3 I acquired fits that bill. I ordered the requisite
parts from Dell, and they came yesterday:
$ 0.73 for the mounting bracket
$ 0.68 for the cable
$ 0.12 for the 3 mounting screws to attach the bracket to the chassis
$11.96 for the 4 screws to attach the drive to the bracket
Oh, and $15 shipping and handling.
