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?.

My $0.02: We use DELL r740xd with NVMe and FreeBSD 13.0-STABLE (with = some NFS patches from Rick Macklem, that are now included in releng/13) and ZFS. NVMe disks are of Dell (type Dell Express Flash PM1725b 1.6TB SFF = 1.2.2). So far we haven=E2=80=99d experienced any issues with them, neither with = the server as such. The only change from the =E2=80=9Cstock=E2=80=9D state of the HW was = that we replaced Broadcom bnxt(4) NIC with Intel ix(4) NIC. The server provides NFS shares for OpenStack compute nodes. otis =E2=80=94 Juraj Lutter otis@FreeBSD.org
