Hi, today was my first time using Target Disk Mode and it took a lot longer than I expected - around 35 minutes to transfer a 75GB file.
In my opinion, it was pretty ideal conditions for a fast transfer between:
an M1 MacBook Pro (16-inch, 2021)
an M2 MacBook Pro (16-inch, 2023)
transferring a single video file of around 75GB
via a USB-C to USB-C cable, capable of up to 10Gb/s (AKA 1.25GB/s)
As both of the MacBooks are capable of up to 5GB/s, I assumed it would be the cable limiting the transfer speed to 1.25GB/s, and therefore the transfer would take around 60 seconds, maybe we can even say 90 seconds to be generous, but 35 minutes is nowhere near to what I was expecting - more like 35MB/s, or in the words of an Apple Keynote - 35x slower than it should've been.
Does anyone know any potential reason that would cause a transfer to be significantly slower than 1.25GB/s between these two MacBook Pros?
