Interface Transfer Rates
InterfaceTransferRates
Transfer rates depend on a number of factors, including the device accessed the
type of transfer, and cycle usage.
The table below includes typical transfer rates for the Optibit and USB interfaces at
a 50% cycle usage with RP/RX and RZ devices. All values are MB/s.

UZ3 transfer rates are highly dependent on the specs of the computer.
Because of the overhead required to poll the hardware or run single commands with
the USB interface, users should be aware of the following relationships when
performing small data transfers with the UZ2.
