Thanks for the responses with great info!  I installed a Samsung 970 EVO 500GB - NVMe PCIe M.2 2280 SSD, using board v2.1 with bionic-lxde-rockpro64-0.7.9-1067-arm64.  Works great   Big Grin  but hopefully we'll get more performance in the future with newer firmware &/or OS releases?

With my ROCKPro64 and Samsung 970 EVO:

Code:
sudo hdparm -tT --direct /dev/nvme0n1

/dev/nvme0n1:
 Timing O_DIRECT cached reads:   1110 MB in  2.00 seconds = 555.17 MB/sec
 Timing O_DIRECT disk reads: 1668 MB in  3.00 seconds = 555.50 MB/sec

With my Intel i5 NUC  and Samsung 950 PRO:

Code:
sudo hdparm -tT --direct /dev/nvme0n1 

/dev/nvme0n1:
 Timing O_DIRECT cached reads:   1978 MB in  2.00 seconds = 989.90 MB/sec
 Timing O_DIRECT disk reads: 3210 MB in  3.00 seconds = 1069.41 MB/sec
