(5 stars) Digital life in a box!

By: hughster
I use this with Macintoshes - I have one large SSD containing OS and applications and home folders, and one large 72k spinner containing other data (photos, etc). I move this box, rather than a laptop, around from place to place, and though this occasionally results in licensing and activation issues, I feel happier with this as a solution than with a laptop.
