For the floppy type tape drives as used in the ftape/zftape driver, in order
to avoide excessive tape ware and head damage the driver needs to keep the
tape streaming, external compression programs often fail in this respect as
they don't have the feed back on the tape status (I've been use gzip -1 with
ftape which just about streams on my 486/33).

But for me the important difference between ftape/zftape is the qic80 standard
support, it is a lots easier to be able to use the same tapes under dos and
linux rather than keep two sets of tapes.
