I kind of stumbled across it by accident - (because) while resetting my tablos and “changing” drives with each other. Tablo2 came up as tablo1 with all it’s data intact. For me it was a pita, I didn’t think of it as “drive swapping” until @Steve427 brought it up in detail.
Personally I would not recommend it as a regular activity, although Steve427 has different experiences - likely depends on one’s skill-set.
Cloning or copying files (rsync) or even the backup-tablo.sh are fairly/really easy (just time consumeing), there are detailed instructions in several topics.
