might be more popular with that crowd that doesn't backup on icloud but to their local desktop. For that non icloud folks I wonder how many use cable vs wifi.
I’m using WiFi 6 (not even 6E) for that and the limiting speed factor for me seems to be the SSD that I am writing the data to. I could throw money at that to make it faster, but I also don’t really care because I’m asleep while it’s backing up anyways, just like how you probably couldn’t tell me how long your iCloud backup takes.
I am a bit surprised there isn't a Thunderbolt controller in the Pro, though. Seems like they already have the IP since it's part of the iPads already.
