That's definitely the ideal option, if you're willing (or have a go-fer
required) to keep shuttling it back and forth.  Of course, the less
often you shuttle it, the more data you potentially lose when the active
drive suddenly fails.

It think it will result in less strain on the mirror drive, but I'm not
sure how much.

You can do a RAID0 using pretty much any kind of software RAID, but I
agree the fire/theft argument is very valid.
