I don’t care about the data on array 1 and 2, but I absolutely have to keep the array 3 data intact. It’s got all my archives, including 20 years worth of family photos.
So here’s my question. If I reconfigure all the drives in the BIOS as AHCI, can I retain array 3 using Linux-native drivers?
The end goal is to have a Linux system with Windows 10 available via KVM + GPU passthrough so I can still do Rhino 3D, Alias AutoStudio and a few games.
The size doesn’t really matter. If one of disks fails, your data is gone.
You’d want at least a bit of safety e.g. raid 5 (and a backup on top of it !).
Since you call it “Archive” I’d assume data is accessed rarely and pure performance does not really matter anyways…
So:
Get a backup drive and copy all of your data to it
