IMO any kind of storage device should be treated as if it could fail at any time without warning. You should have a plan for what you will do WHEN this happens, not IF it happens. If losing a storage device would result in you losing "something important" then you're doing it wrong. I keep all my spinning disks in some kind of RAID unless their contents are completely expendable (ie I won't be upset if I completely lose it). For SSDs I generally do frequent rsync or zfs-send backups to a spinning disk - these are generally used for OS data which doesn't change as much anyway, and the backups are quick since they aren't large. If I had large SSDs I'd run them in some sort of RAID. And of course anything I consider really important gets backed up to the cloud, encrypted. RAID is more about avoiding downtime and the inconvenience of an offline restore. -- Rich
