I have my two 2TB drives partitioned to D,E,F, and G drives. My C:/ drive is a 1TB drive. I do partitioning as it makes it faster to copy the contents onto backup drives. I use Acronis for the C:/ drive only. After the initial copying is finished I do clone the copied drive two more times. I use an Inateck unit:

It does a perfect job and it isn't very expensive.

Whenever I get something stuck in the back of my throat, I dislodge it by drinking a beer.
It's called the Heineken Maneuver.
