Does any M.2 make sense for me?

Hey, so I have my boot drive now as a Samsung 850 Evo SSD. Its pretty fast. But after upgrading to Intel and a high end mobo that includes M.2 slots, im looking at the option now. Im a little confused though, because the 850 and say this M.2 here: http://www.newegg.ca/Product/Product.aspx?Item=9SIA9H53WY6077&cm_re=m.2_ssd-_-0D9-0006-000G3-_-Product
have roughly the same read and write speeds. It wouldnt even make sense to but one, would it? I know that the Samsung 950 M.2's have over 1000 read and write speeds, but I dont have that kind of money. Does an M.2 like the one included here really make sense??

M.2 is a form factor. M.2 drives can use either a SATA 3 interface or a PCIe interface, the latter being faster. To answer your question, no, there's really no benefit in getting an M.2 SATA SSD compared to a regular 2.5" SATA SSD.

I am in reality, thats why im asking. I was wondering if there was something I wasnt seeing. Just dont understand why they would make them those speeds when unlike Sata which has topped out, M.2 is capable of so much more. Figured maybe there was some advantage to M.2 over an 850? Doesnt sata actually top out at 300 Megabits per second at the Mobo connections?

Sorry to butt in but wouldn't space be a benefit? I'm relatively new to M.2. Been reading a lot about it the past few days trying to figure out if it's a good idea to get one of those.

The current case I have already forced me to move my HDD's around so I could fit the GPU in. If I were to install an M.2 as my system drive it would save me a lot of cable management. Only issue I'm worried about is PCIe lanes. I'm rocking an Asus Z170-A and if I understand correctly this means the board itself has 20 extra lanes on top of the 16 lanes supported by the CPU, right? So in terms of future SLI I have nothing to worry about?
Just in case, relevant specs:
CPU: i5 6600k
Mobo: Asus Z170-A
GPU: GTX 760

Yeah, you're right, M.2 does have an advantage in taking up less space. I figured that for the vast majority of desktop computers it wouldn't make much of a difference, but I guess it could come in handy for some people.

Based on Asus's specs for that mobo, it doesn't look like the M.2 slot shares bandwidth with the PCIe x16 slots, so you should be good.
