Quibble, but don't you mean "the longer it will take to depressurize?"
I'd think the rate of leakage would depend on the size of the hole,
not the size of thing in which the hole was made.

Yes, that's probably a more accurate rendering of what I meant to say.

That and with the greater volume, you can design it so that it is easier
to access the inside of the pressure wall so that a patch could be
applied to any hole which is causing a leak. On an inflatable, you put
the equipment along the central axis because that's where the structure
which supports launch loads is located.

On ISS, the walls of the aluminum skinned modules are almost completely
covered up with equipment. Getting to a leak on ISS could be quite
involved, depending on where it is located.
