Here is a link to an M2 form factor SSD (and some details from the description): (The example is a Samsung, and I found the example at Newegg, but this should not be considered an endorsement or advertising for either of them.)
By the way, the dimensions of these units vary, and the dimensions are encoded in the form factor, for example, the example M2 2280 device is 22 mm wide by 80 mm long (about 1" x 3"). (And 2.38 mm (~0.1 inch) thick, but, as far as I know, the 2 in the M2 does not designate thickness -- I could be wrong.)
