Anyone else have a test they'd like run before it goes into production?

If you can do the freebsd current with
diskinfo -wS /dev/nvd0
/dev/nvd0 or what ever device it assigns to it thanks. I want to see the difference in freebsd nvme driver performance to use it for freenas if you have the time

Code:
 fdisk -l /dev/nvme1n1

Disk /dev/nvme1n1: 8 GiB, 8581545984 bytes, 16760832 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
used -o ashift=12 no problem.

Good luck spoke to them on Monday... maybe if you have a job that relates to the field they will listen but they told me they only sold those to oem and such... kinda like my quest with pmc...
