I currently run Proxmox on a DeskMini H470 with an i5-10400 and 64GB DDR4 (non-ECC).
I have about a dozen VMs/CTs running, with one of the VMs running about 25 Docker containers. The Proxmox box hovers around 5% CPU usage and 60% RAM usage.
Proxmox is installed on a Samsung 970 Pro 512GB NVMe SSD, and my VMs/CTs live there too. I'd like to add 2x1TB enterprise-grade SATA SSDs, setup a ZFS mirror, and then move my VMs/CTs to that storage. Proxmox would remain on the NVMe drive. Backups are handled by Proxmox backing up to a separate NAS.
Here is my output from iostat against the NVMe drive. I'm assuming I want the 1st (r/s) and 7th (w/s) columns to see IOPS?
I have analysis paralysis and can't decide which SSDs I should purchase. I'm currently looking at these drives. Because my IOPS are so low, I could reasonable purchase any of the drives below, right?
