Well, I'd wager they use it for pretty much anything and everything you 
can use storage for.

I spent six years at NASA/JPL, nearly four those years developing 
software for the DSN SFOC NOCC-RT¹, and a bit for Galileo S-Band², among 
others; none of those nearly as exciting as the Curiosity rover though.

Yes, certainly they use it for science data like images, but also the 
rest of the scientific data that's not images. Add in non-science data 
like spacecraft and rover telemetry, telemetry from all the ground-based 
equipment — antennae, receivers, exciters (a.k.a. transmitters), and 
etc. And perhaps even just storage for mundane things like software 
developers home dirs. JPL does lots of software development.

¹Deep Space Network, Space Flight Operations Center, Network Operations 
Command and Control-Real Time.
²Galileo's big high gain K-band dish antenna for high bandwidth 
downloads didn't open. They compressed the mission data and sent it from 
the low gain S-band and used intensive signal processing on the ground 
to pull the data out. They ended up collecting more data than they 
originally planned or expected to get from the K-band radio.
