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.

USB adapters will work well until you are _absolutely_ reliant on them,
then there will be a problem in my experience :(

Yes, absolutely agreed with David on this.
