I'm thinking more in terms of the process of development as a whole. Not so much, specific tasks directly related to programming. You eventually have some code editor opened, external documentation, auxiliary applications of all sorts, possibly even a local database... essentially we tend to end up with a working set of applications that is ripe with file IO operations going in the background to support them.
But depending on your type of development, I suppose you may also gain directly much from this technology. For instance, there's a lot of IO going on when coding for data access using editors that can connect directly to databases, including remote databases. I necessarily agree though, that for the specific task of coding and building there wouldn't be much of a benefit.
