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? One box with two NVMe (my packet-builder host), running CURRENT. Model Number: Samsung SSD 970 PRO 1TB Works fine, no problems. I have not measured throughput, but I guess NVMe is faster than SSD, due to the SATA bottleneck etc. Several boxes with SSD Sata (mostly Samsung SSD 850/960 and some with Intel S4510/S4610/S4500/S4600 Series SSDs), all work fine. There were issues with Samsung SSDs and AMD EPYC 3251 CPUs. That's when we brought in the Intel SSDs... > Do you recommend one over the another?.
