I'd recommend against using raid-z(X) on a USB enclosure. The throughput to each disk just isn't there.
Also, my experiences using ZFS(onlinux) without any raid (i.e. single disk with "copies=" > 1) is that it wasn't very resilient against any kind of I/O error - even if the cable was bumped or something. This has resulted in the loss of a whole zpool and restore from backup.

- mocko 10y agoIs the throughput bad even with USB3? You're looking at 625MB/s which even after signalling overhead ought to be sufficient to saturate 3-4 magnetic disks. Latency might still be a concern but personally I've always found [non-ZFS] throughput to be great.
