Is there a preference for either CF or SD card?

External with SD card. While I was able to get some CF cards fairly
cheaply, SD are much easier to find in smaller sized formats. They
have micro sd to SD converters if someone is keen on using those.
yanking apart the iic is not desirable but also, should it work on a
IIGS then being able to quickly move it from machine to machine is
highly desirable.
