And as for nVME, some magazine did a "test to destruction" of solid-state drives. They lasted almost for ever - I think the computer(s) were configured to hammer the drives 24/7 and they lasted over 18 months - that's probably a decade and more in normal usage. The one thing to watch out for, is that if you DO encounter problems, DO NOT shut the machine down. If a drive suffers failure, stage 1 seems to be to go read-only. YOU MUST back it up immediately, because stage 2 is to commit suicide on reboot. But you're highly unlikely to meet that scenario in normal use. I'm planning to buy one of those shingled horrors - a Seagate BaraCuda 12TB - for backups. Use btrfs or LVM, and rsync in-place copy. A good idea in any case, but probably an even better idea if your main storage is SSD. Cheers, Wol
