Interesting. I have been thinking of a smaller SSD for the OS, and 4 800GB for vm's and active data, and some hard drives for archival and backup. I did not realize that nvme can be used with an adapter, and I do not have motherboard support. I am struggling to figure out if I am better to use a couple of new 5TB Toshibas or similar, or something like the 3TB drives posted above. I also have a couple of 2TB drives very under utilized with small amounts of data that can be added for additional storage, which I assume can be used if I flash my Intel RMS25KB080 into IT mode. As I am in an apartment, noise is an important consideration, and also power and heat.
Time will tell, but I imagine that over the next few years SSDs will continue to get bigger and cheaper very quickly.
