we have 3 HP 820 Elitebooks, they all have the m.2 slot.
they are plug and play, a second SSD in all respects. I bought another
one on eBay a couple months ago: 512GB 512G NGFF M2 2242 SATA SSD

$80 usd with shipping. the "2242" is the length, very important

m.2 is my boot drive, the conventional 2.5" ssd is my secondary drive

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.)
