October 9, 2025Oct 9 I am currently running a 2 sata drive BTRFS raid0 for my cache and a 2 nvme drive BTRFS mirror for my dockers and VMs. I keep having issues with nvme drives on my server and not sure what is causing it, it might be the motherboard. So I am switching out the NVME drives for sata and bought 2 1TB drives. Now I have 4 identical sata drives and am wondering what would be faster now that I am using SATA instead of nvme. My options are.2 drive stripped for cache and 2 drive mirror for Dockers and VMsOr4 drive ZFS raidz1 for cache, Dockers and VMs on one pool. I'm leaning towards this one.

October 9, 2025Oct 9 Community Expert Raidz1 is not great for VMs, low IOPS, you could have a single pool with two stripped mirror sets.
December 6, 2025Dec 6 I agree, raidzX isn't good for VM. Prefer a stripped mirror (RAID 10) for VM. That's a usual practice above any raid or filesystem solution.
