I have a pi4 running on an ssd over usb3 with a usb3 dock that has 2x2TB drives for storage.

At the moment I have mainly music on one and mainly video on the other, with important stuff on both and elsewhere.

Is it sensible to combine 2x2TB hdd’s via usb3 dock into a 4TB filesystem/pool/volume/thing…and if so can I have tiered storage so if one drive fails the other will have a mirror of important stuff?

    What you’re looking for is a backup. RAID is not a backup, as another poster said it’s a tool for enduring high availability, and possibly higher throughput.

    Buy a second pi and put it in another location in your house or even better at friends house then configure regular backups of your important data to it. There are also cloud services for doing backups which are great because having a location to do off-site backups to can be really hard to get as an individual.

      Thanks, I do have backups of important stuff.

      I think bcachefs is what I’m looking for, but I’m gonna wait a bit until development calms down a little and keep on the way I am at the moment.
