TheSkaz Posted September 8, 2020 Share Posted September 8, 2020 I got 4 Sabrent 2TB QLC nvme drives (PCIE 4) and want to use them to run my VMs off of them. I used to have 6x SSDs with raidz (ZFS) and am getting rid of those. Would a "Raid 10" (https://calvin.me/create-zfs-raid-10-array-napp) be best in zfs or a simple raidz? I know with software raid 5 in windows, performance would slow down because of the CPU. I want speed and redundancy. Quote Link to comment

To Windows, I believe the source location will simply look like "a disk". It's unRAID/hardware that will detail with all the RAID details. Quote Link to comment

I was referencing old knowledge from motherboard "software raid" setups. I know the VM doesn't care. I was curious of the best setup within Unraid. Quote Link to comment
mikeyosm Posted September 25, 2020 Share Posted September 25, 2020 Wont the VMs be bottlenecked by the virtio scsi driver? QEMU needs a stable working nvme emulator driver for VM guests so we dont have to passthrough nvme drives to gain maximum performance. Quote Link to comment
