@xrobau@mastodon.au @LapTop006@aus.social A SATA SSD can make sense for a log or special vdev, but never really makes sense for a cache vdev. They’re too slow at mixed workloads, and a cache device always has a mixed workload. For an NVMe-only pool, AnyRaid may be worthwhile. It gives you the flexibility to use whatever drives you’re able to get without the smallest limiting capacity of the whole vdev. With five 1TB drives and one 256GB, raidz1 would give you 1.25TB, while AnyRaid would give you 4.25TB. It’s like how Drobo worked, but with ZFS durability and performance.
