CMS also sells separate controllers, FC-10 and TC-15 which run at twice the transfer speed of the floppy drive controller. The TC-15, furthermore, does compression in hardware (if the option to compress is chosen), further decreasing the tape transfer time. Contrary to the expectations of many readers, with these tape drives, there is no drive letter assigned or involved, so an unused drive controller port for a floppy or HD has no use.
