Is there a way to add a Firewire "800" port to the MacBook Pro "Core Duo" 15-Inch systems?

Please note that the MacBook Pro "Core Duo" series was discontinued on October 24, 2006. It was replaced by the "Late 2006" MacBook Pro "Core 2 Duo" series which includes a single built-in Firewire "800" port. Two additional Firewire "800" ports can be added to any MacBook Pro model using the solution below.

There were numerous cheers when the MacBook Pro "Core Duo" 2.16 17-Inch was introduced with a Firewire "800" port, like the PowerBook G4/1.67 17-Inch (SLSD/HR) that preceded it.

It is possible to add Firewire "800" ports to complement the single Firewire "400" port on the MacBook Pro "Core Duo" 15-Inch systems via the ExpressCard/34 slot. Readers not already familiar with the ExpressCard/34 standard may first wish to read the answers to:

• What is ExpressCard/34? Is it compatible with PC Cards?
• What is the difference between ExpressCard/34 and ExpressCard/54? Speed?

Both Belkin and SIIG were quick to announce ExpressCard/34 cards that provide dual Firewire "400" ports, but sadly neither initially supported MacOS X (SIIG later added MacOS X support).

Fortunately, NitroAV was the "industry first" to release an ExpressCard/34 expansion slot with two Firewire "800" ports for the MacBook Pro, supporting MacOS X 10.4.6+. The company describes that their product:

Allows you to easily connect your FireWire 800 peripherals to your ExpressCard[/34] slot. ExpressCard technology is different than PCMCIA because it has an increased transfer rate and better efficiency between the computer and external peripherals.

This ExpressCard [provides] 2 FireWire 800 slots (2x - 9Pin) connectors. You can use different cables to match your particular FireWire peripherals depending on what you need. With the FireWire 800 protocol you can get transfer rates of 100, 200, 400, and 800 Mbps.

After NitroAV, other companies, including APIOTEK, EZQuest, SIIG, and Sonnet released ExpressCard/34 expansion cards that are compatible with all MacBook Pro models and provide Firewire "800" ports. Site sponsor Other World Computing sells a wide variety of these ExpressCard/34 expansion cards.
