Western Digital unveiled its SanDisk 1TB SDXC card...
Weird, even on an old PCIe 2.0 Opteron machine, I easily gets 1.4 GB/s from an HGST NVMe card. I've got 800 MB/s from a single SAS 12Gb SSD. Something's probably wrong in your setup.

Same as you, good ol' dd. Not using direct IO, though. But I'm watching at iostat while testing, and the results are coherent.
