Matthew Dillon has written a new, from scratch, driver for NMVe in DragonFly. If you haven’t encountered it yet, that’s SSD access over PCIe, which gives better throughput than ATA. He’s posted a summary of his work, and it’s possible to load it now as a module. It supports MSI-X, and there’s test results from using dd on supported NVMe hardware.

This is truly exciting from the Dragonfly team! Can’t wait to get swapcache fired up on one of these drives!
