M2 NVME support

Hi!, 

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
(probably Samsung PM* ones). How is you experience with them?. Do you
recommend one over the another?. Is perhaps better support from some of
them from a specificic version to newer?. Or do they perhaps work better
with some specific disk controller?. 

Best regards,
