During the process of setting up a new proxmox server, I asked some questions around the forums and another situation arise that caused me some concern.
The question was related with the use of SSDs for ZFS on proxmox.
So I was thinking that I had a pair of samsung 860 pro 250gb to use...
Good day to all,
I setuped RAID-5 configuration and did some disks performance/efficiency tests. Main idea is to check RAID-5 efficiency with this server configuration:
CPU: 48 Cores @ 2.8 GHz
RAM: RAM DDR4 256GB 2400
Disk: 4x NVME 500GB (Samsung SSD 970 EVO Plus 500GB)
Raid Level: Custom
Smartmontools not working for Samsung Enterprise SSD SAS PM1643 for wearout.
I wonder if smartmontools 7.1 that is in Bullseye do work for these ? Is it possible for Proxmox to backport ?
I only get this from smartctl -a:

I have a Samsung 950 PRO PCIe NVMe 512gb M.2.
I just installed Proxmox to test-out Windows Server 2016 in it.
I went with viostor because that's the only driver during the install windows accepted, expect for SATA and IDE but they are too slow.
Super fast read speeds!!! 6,550 MB/s.
Seeing something very odd with Samsung 850 Pro SSD as Ceph journal. When running tests for speed as per:
