There are basically two ways to speed this situation up:

1)  Write to a RAM buffer and do the actual Flash write in the background.
(I'm sure you've thought of this).

2)  Make sure there are always freshly erased blocks on the Flash when you
come to need to do a fast write.

Either way, DOC2000 is never going to be any great shakes of speed-  it's
just not a very fast device.
