I have two identical external hard drives while on the road.
To make images more secure I download each image to both drives.
I cannot stress that enough, as I have had several external drives fail over the years,
and it is a terrible feeling when it happens.
Back in my office I have an 8TB Drobo as well as another external.

Behind the laptop is my Kindle Fire playing music through the speaker on the right.
I always enjoy music when working.

I also bring an 8 outlet power strip to charge multiple camera batteries at the same time.
