m.2 drives are available in both SATA type and NVMe (pci express) type. Either will work in your board, the specifications say it supports both.Is there anything I need to worry abot using the M2 drive with the above board? It seems to me that there is really no reason to use the standard SATA type SSDs any longer, especially when you can use M2 enclosures for external use now. Also, if you know, I've always used Samsung SSDs. Unless there is some problem, I'd like to stick with Samsung for the M2. Any suggestions?
I’m assuming by “standard data ssd” you mean a typical 2.5” size. Still plenty of good reason to use those, but the main reason is... a lot of boards might only have one or two m.2 slots. So if you need more storage than that, it’s the only way. They are also available in higher capacities than m.2 drives (Micron, for instance, has a 7.6TB 2.5” ssd).
nothing wrong with Samsung if you can get them for a good price. But they’re overpriced these days. Best deal going for NVMe drives is probably the Inland Premium drives at Microcenter (and MC now sells them on Amazon as well). Price typically hovers around $110 for 1TB and as I recall they’re quicker than Samsung 970 evo drives.
