I have 2 500GB SSDs in RAID1 for important data, truenas apps etc…, then 32TB total in RAIDZ1 for large Dataset that won’t need speed (movies, TV show, music, pictures, archives,…)

If I have a complete NAS failure, a remote backup (via rsync to a friend’s NAS Weekly) of the SSD and bootable drive can be used in a new system, and my torrent app has the list and magnet of all torrents stored on the SSD so it can re-download them.
