> Would Samsung 970 EVO Plus NVMe drive be considered consumer grade or enterprise?

This is a consumer SSD, by Samsung's own classification: https://www.samsung.com/semiconductor/minisite/ssd/product/c.... The 970 Pro goes into prosumer territory. The DCT range are their enterprise drives: https://www.samsung.com/semiconductor/minisite/ssd/product/d...

> Also, are NVMe drives susceptible to faster degradation due to higher throughput

Only if you use the time saved to write more data than you would have with a slower drive. e.g. for 1TB both the 970 evo (nvme) and 870 evo (sata) are covered by warranty for 600 TBW.

The 883 DCT on the other hand offers 0.8 DWPD for 5 years or drive writes per day. So 5 * 365 * 0.8 = 1460TBW, or about 2.45x the consumer drive
