if i understand correctly in your test time is spent evenly between io and cpu? 30 seconds for each, does that mean there is no real bottleneck?

No, the CPU is the bottleneck here. We should be able to do better than 50% CPU usage for 1.4GB/s. Probably the actual bottleneck is the allocator; we allocate a bounce buffer and free it for every single transfer.

NVMe also comes in other form factors than M.2 such as U.2 and PCIe cards which are even faster than M.2 drives. Also there is NVMe over thunderbolt once that is perhaps someday supported.

I have a M.2 PCIe adapter I intend to test with an HP EX900 SSD also.
