5Ghz wifi and Airdrop is what Apple wants people to use. I stopped connecting a USB cable except for doing a physical backup with iMazing on this 256GB model. I just trust the hard line more when making a 232GB backup.

• USB2.0/3.0 = 480MB/s
• USB3.1 G1 = 625MB/s
• 5Ghz Wifi = 850-1000MB/s
• USB3.2 G2x2 = 2500MB/s
