Sometimes there are nifty things that are invented that make complete sense and this is one of them.

This is a flash drive that’s black with domino-style dots on it. Each time a dot appears, it means 1 gig of space is in use.

What’s even better is that these flash drives interlock. While that’s not a particularly new concept, two of these locked together make up one domino and the dots still follow suit.

The reason this makes so much sense is that you can instantaneously tell how much space is left on one of these just by physically looking at it.

Very cool.

ALL flash drives should have indicators like this.
