My bad, the Express DOES NOT have hard drive capability. I think it all comes down to whether you want to spend the extra $80 for an Extreme. Both are excellent routers, and the express will do more than enough for you.

As for the Airport's in general, they are the BEST router you will find. Before I bought my first Airport, I spent almost a year and a half buying different wireless routers. I bought EVERY SINGLE wireless Linksys router (No Joke) both business and personal editions for a year as well as many other Belkin, Netgear, and Hawking routers and accessories. None of them ever came close to the Airport extreme or express.
