Using FireWire on a Raspberry Pi

Using FireWire on a Raspberry Pi

After learning Apple killed off FireWire (IEEE 1394) support in macOS 26 Tahoe, I started looking at alternatives for old FireWire equipment like hard drives, DV cameras, and A/V gear. I own an old Canon GL1 camera, with a 'DV' port. I could plug that into an old Mac (like the dual G4 MDD above) with FireWire—or even a modern Mac running macOS < 26, with some dongles—and transfer digital video footage between the camera and an application like Final Cut Pro.

This is an awesome project.

I have a long-in-the-tooth investment in Fireware audio devices (Presonus) in my studio - 19” rack interfaces with 10 I/O’s, as well as the StudioMix mixer with 20 or so .. I’ve been keeping an aging iMac around to use all of this with and it still just plain works, but having the option to replace it with an rPi is really appealing. The system is mostly used for tracking, so having REAPER on the rPi, connected to all that FireWire gear, just seems such a nice idea…

I wonder what the load will be like, though? Can the latest rPi with PCI hat and Firwire interface handle 40 channels of audio over FireWire, I wonder? I know the issue would mostly be SD-card write speeds and so on .. maybe this disqualifies the rPi - but certainly there are other ARM-based SBC’s that this same technique could be applied to ..

Audio shouldn't be a big problem for the Pi unless you're pumping it through tons of heavy filters. The Pi 5's CPU can hold its own against 2010-2015 era iMacs, and a good microSD card easily holds 40-50 MB/sec writes.

For better performance, I'd plug in a USB SSD (USB 3.0 can put through 300 MB/sec or more), or even use built in Ethernet, good for writing 100 MB/sec out to a NAS or another networked computer.

Do you have any preferred SD card brands and models? Speedy and durable cards suitable for RPi
