Best type of SSD to boot from using B250M MORTAR RED mobo

[grmius]

I'm building a budget gaming pc using B250M MORTAR as the mobo. I am looking at using a 250gb Solid State Drive, I have noticed a nice increase in speed when I changed to a SSD in another machine. This board has several options for SSD connectivity, so what type of SSD should I use that would be bootable and provide the best speed? PCIe, M.2, etc.
The other parts I am using are:
GTX 1050 ti
EVGA 450 Bronze power supply
Ballistix Sport LT 8GB Single DDR4 2400 MT/s (PC4-19200) SR x8 DIMM 288-Pin Memory
Pentium G4600
Thanks!

A regular SATA SSD will work just as good as the higher priced true M.2 SSD for a boot drive their little difference in boot time (0.4 seconds).

Samsung 850 evo will be perfectly good.
It performs a bit better than most and has a 5 year warranty.

Since you asked for the best, that would be the samsun 960 evo m.2 pcie nvme device.
Random I/o which is the most important item is not much different from a conventional ssd.
But in sequential operations, it is some 5x faster.

The 960 PRO is a tad better, but probably not worth it to you on a budget build.

Would the M.2 make any difference for gaming/streaming...or would the benefit of the M.2 be more for improved speed for large file transfers, databases, etc?

m.2 by itself does not tell much. It is a format, not an indication of speed.
PCIE x4 is what makes the difference in sequential speeds.

You will notice the difference doing virus scans, for instance with a pcie device.
In gaming, perhaps on level loads.
