Using this has been a life-saver for all sorts of computer activities and I have a box of cloned drives for my LinuxCNC machine, laptop and desktop computers.

This isn't the exact model I have but it's the same sort of thing. Just make sure you know for certain which is the 'source' and 'destination' drive slot

Nice idea, but since the thin client I'm using to run the machine has only 16GB of flash, I can do the same with a USB stick. I might get one for the big machine at home though.
