Just to comment on this, my friend in the computer game industry insists that compression begets speed in almost all data handling situations. This will be worth bearing in mind as we start to have more fine-sliced Pilatus 6M (or similar) datasets to deal with.

I think they process a bit faster too, because half the information is packed into the resource fork.
