m.2 Hard drive ??

[dal]

Hi all, so sorry for the basic question but is a M.2 hard drive the same as a NVME drive & would it give me a performance boost over SATA ?

Also is it better to have the operating system on a separate drive ?

This might help explain some of the differences:

Cheers, just read through that, so have i got this right :
A m.2 sata ssd won't be any quicker than a normal sata ssd and a nvme is not really going to be quicker for general computing and gaming which is what i will be using mine for so i might as well go for a standard SSD
