Apologies, I was replying to the following from David Rankin:
Good, I don't feel like such a dinosaur with RAID1 ext4 on spinning rust -- which has been incredibly reliable:

Though I do keep a close eye on the drives given their age, and have spare available -- and knock-on-wood often :)
It should make sense now :) Take care, -- Polarian GPG signature: 0770E5312238C760 Website: https://polarian.dev JID/XMPP: polarian@icebound.dev
