OWC Mercury Elite-AL Pro Dual mini Chapter 1 - Introduction
1.4 Port View & Cable Connections
➀ ➁ ➂ ➃ ➄ ➅
The OWC Mercury Elite-AL Dual mini comes equipped with multiple
connection interfaces to ensure the maximum computer compatibility
and portability.
FireWire
The Mercury Elite-AL Dual mini features two FireWire 800 ports ➀ and one
FireWire 400 port ➁. FireWire 800 provides speeds up to 100 MB/sec and
FireWire 400 provides speeds up to 50 MB/sec.
The use of FireWire does not require any auxiliary power source as each port
carries enough bus power to run the Mercury Elite-AL Dual mini directly
from the computer’s FireWire port.
FireWire also has the ability to daisy-chain or connect multiple FireWire
devices together through one FireWire connection to the computer. OWC
recommends having only one bus-powered device in the chain due to the
limited amount of power a single FireWire port can provide. If a FireWire 400
device is chained with FireWire 800 devices, all devices will throttle down to
FireWire 400 speeds.
USB
The Mercury Elite-AL Dual mini features one USB mini port ➂ that provides
speeds up to 60 MB/s.
The USB connection cannot carry enough power for the Mercury Elite-AL
Dual mini, so the use of the optional AC power adapter is needed to con-
nect to the DC In power port ➅.
Please see Section 4.2: Tips for information on purchasing the optional AC
power adapter.
