Type I are the small/ordinary ones, type II are the bigger ones (for micro 
hd's and such). It looks like type II fits, but I've never tried an actual 
microdrive personally. I just installed a sup720 with a 2GB type I regular 
sandisk camera CF the other day (only thing I had available), and it 
worked just fine.

Because then they couldn't sell the CF at 50x markup without it costing 
more than the interface cards? :)

The slow speed at which the CF's are accessed is far more annoying. These 
boxes take too long to boot at it is, without trying to write a 1GB 
coredump to the flash.

The lastest results from people who've tried the internal flash upgrade to 
sup-bootdisk (which is really just a CF with an adapter) are that it still 
only reads at 1MB/s (the same as every variety of external CF). For some 
reason, the native internal flash in stock 64mb sup720s seem to do 2MB/s.
