Miniature cdrw-maximum record speed?



Hi all:

First of all, thanks for your replies re: my query about the Backpack external cases.

Well, I’ve about given up on trying to find a fast recording, but miniature cd-rw external unit.

I’ve been looking at miniature units from Backpack, Addonics
LaCie etc. But none of them seem to be faster than 8x recording.

Are there any minature (not standard sized-read: Heavy
units that can record at faster than 8x, or is this some kind of
limitation of the miniature units today?

Thanks for your expertise
