Performance Up to 2.6MB/s read, 2.3MB/s write

(1.1MB/s on most older SCSI hosts) 		Up to 1MB/sec Up to 10MB/s
USB Interface Firmware updates and configuration
USB 2.0 micro-B 		Firmware updates, configuration, and mass-storage
USB 2.0 micro-B. Mass-storage at USB 2.0 FS speeds (1.2MB/s max)
Power 5V via:
* standard 4-pin floppy-drive connector
* micro USB
* self-powered using the SCSI host termination power

 5V via:
* standard 4-pin floppy-drive connector
* micro USB
* self-powered using the SCSI host termination power
* Regulated 5V via optional DC barrel jack.
 Self-powered using the SCSI host termination power,
or via USB. 2.35W maximum (500mA)

To function without external power via USB, requires SCSI host that
supplies terminator power on pin 25 of the DB25 socket 		5V via standard 4-pin floppy-drive connector, USB,
or self-powered using the SCSI host termination power

Current Draw 2.35W maximum (500mA)
