Is n.2 NGFF SSD in the 256GB the best way to go

[sebastian869]

Basically i'm looking to install one SSD for OS boot and any other "mission critical" purposes and i figure 256 GB should be enough. Could you guys please give me your opinion, since it would also influence the MOBO id go with. Lastly, i'm new to SSD could you guys please tell me which drive would be best. From homework i did i got:
Samsung 840 EVO 250 GB ,,,,SanDisk X210 ,,,, but those were not n.2.
Thanks.

pretty sure you meant M.2 not N.2. In that case dependning on the SSD you get then yes a M.2 would be faster
