Gene, Are these 2TB SSDs or hard disks? I would counsel very strongly indeed against using any ARM-based single board computer as a RAID device on USB connections - they're just *not* up to it. Get a cheap barebones system that you add memory to in a small-ish size case with SATA cables to motherboard ports that's Intel/AMD based that you can then put disks into to format. If you can't get a barebones, at least get a second hand machine in a tower case. Build a simple Debian system on one disk there to format other disks :) Once you've built a simple Debian system there, you can add mdadm RAID and use it as a backup storage device to copy off your /home and so on. > Startech adapters are working very well to a pair of smaller SSD's on the > rpi4b that runs my old (80+) Sheldon 11"x54" lathe, teaching it new tricks > it never dreamed of doing 80+ years ago.
