Samsung Evo M.2 SSD

[Marky]

Hey all,

I was just about to purchase a Samsung Evo 850 500GB SSD, however I noticed that the M.2 Evo 850 500GB SSD is only very slightly more expensive...

I don't know the technology too well - Is there much of an advantage of getting an M.2 as opposed to an actual SSD?

Thanks,
Marky
