to get a list of FireWire drivers that are not compiled for arm64e (none that I could see).find /System/Library/Extensions -type f -ipath '*/Contents/MacOS/*' -exec printf "%s " {} \; -exec lipo -archs {} \; | grep arm64 -v
I had an OWC FW800 RAID up until recently and the speeds were indeed not bad. However, after buying a USB 3 drive, which was primarily to reduce clutter/save space, I realized just how far behind FW has gotten in comparison to today's I/O.They're plenty fast for the HHDs, and I see no reason to buy new cases, which would end up costing more than the adapter.
I have both so I can test.You’ll need a TB3 to TB2 adapter and also a TB2 to FW800 adapter if you don’t already have one.
