How large is "rather large"
If up to about 8 GB is ok then read on.

Generic cheap and available SD "camera" Flash seems like a 
good choice.
Up to a certain size it has a serial SPI mode - and above 
that it may.
At all sizes it has a nibble mode which probably isn't too 
much harder to drive.
AFAIK a number of people here have interfaced to SD OK.
Including our beloved list owner James if memory serves.
