I think the MMC interface is the simplest you can find for mass storage.
I wrote some code to talk to one on a PIC 18F and added enough code to
write files to a preformatted fat-16 file system.  it wasn't that hard.

if you can do it on a pic a z80 should also be possible.

USB on the other hand, especially usb disk, could easily exhaust the
memory space of a z80.  i'm sure it coud be done but it would take a lot
of code (and time).
