My tuppenceworth:
2x Gold 6338 2GHz
ZFS pool - 10 disks Samsung PM9A3 7.68TB, 5 mirrors
Gigabyte R182 NA0

No issues. Server is used as iSCSI provider for VMs (performance testing
farm for databases).

&gt; Hi!,<br>

&gt; We are in the process of buying new hardware for use with FreeBSD and =
ZFS. We are planning whether to buy M2 NVME disks or just SATA SSD disks (p=

a specificic version to newer?. Or do they perhaps work better with some sp=
ecific disk controller?.<br>

My $0.02: We use DELL r740xd with NVMe and FreeBSD 13.0-STABLE (with some N=
FS patches from Rick Macklem, that are<br>

NVMe disks are of Dell (type Dell Express Flash PM1725b 1.6TB SFF 1.2.2).<b=

So far we haven=E2=80=99d experienced any issues with them, neither with th=

The only change from the =E2=80=9Cstock=E2=80=9D state of the HW was that w=
