i don't have a strong opinion either way on usb speeds because i don't understand what difference it makes anyway? i don't think there's even a way to access the file system directly. genuine question: who is transferring data to or from an iphone using a lightning cable on current iphones? what kind of data? i've used only iphone since 2015 and the only time since then when i've connected my phone to a computer was when i was playing with jailbreaking iOS 9 and none of that stuff involved transferring significant amounts of data one way or the other.
