I stand corrected...  Perhaps I should have said 2-4 times as much storage.
                      The comparison is with a standard 360K 5 1/4 inch floppy.

I think that the more significant point was that the folks at the product
announcement told me that the new drives are ESDI-based, significantly
faster and are linked to a SCSI bus interface. That alone CAN mean transfer
rates in excess of 1 MB/Sec.[unexaggerated] (even on single-ended SCSI). This
is (of course) quite dependent upon the PS implementation. It is certainly
significantly better than the hardware limitation of ST412/506 to about
625K/Sec. and may make these more worthy of multitasking applications.
