This.
I’d definitely avoid a RAID card. If I can do advanced encryption with an MMX instruction, I think I can certainly trust IOMMU to handle device multiplexing from software in an efficient manner, no? mdadm RAID is just fine for me and is reliably bootable from GRUB.
I’m not an expert in driver mechanics, but mirroring should be very low overhead at the software level.
Once it’s software RAID, moving disks between chassis is a simple process as well.
Apologies I didn’t make that clear earlier...
Yes, I really like mdraid :) . Problem is BIOS/UEFI has to find a
working bootable disk. I think some BIOS/UEFIs have settings for a
secondary boot/UEFI bootfile, but that would have to be prepared and
maintained manually, out of the mdraid10; and would only work with a
total failure of the primary disk.
Cheers
