  This is "ATA mode", and I think they can all do that (PCMCIA and CF
flash and drives).  Look at some of the data sheets or even the
performance specifications, which often give two sets of numbers for
transfers.  They must have all the IDE logic in them already anyway
(unlike other types of flash where the card is just the flash) so the
additional logic to do ATA is minimal and allows a wider range of use.
