I don't see how a Pi can take advantage of NVMe. From my tests using a 10Gbit USB3 adapter with a capable NVMe drive (3GB/s), its impressive IOPs are reduced so much that they are almost comparable to a 'normal' SATA. I would expect a 5Gbit USB to further limit it.

I have a “normal” SATA SSD plugged in, and it’s running within 10% of the hdparm benchmark in the article (it’s not a 1:1 comparison since it’s an older SSD, cheap adapter, and I have two other HDDs plugged in via USB for bulk storage). At that speed, with those other variables, I think it’s the USB port that’s the bottleneck.
