Has anyone experience or estimates on what transfer speeds are to expect when transferring data to/from the latest gen. iPad Pro 10.5 using a USB-C to lightning cable? Scenarios might be

  • creating an iTunes backup
  • syncing movies, music and other media via iTunes
  • copying photos, videos using iTunes or some photo organizer app
  • transferring documents to apps using the iTunes app documents feature
  • ...

USB 2 is really ancient now, and I expect a modern device as expensive as the iPad to offer faster transfer speeds than USB 2. So it would be great to know if the USB-C to lightning cable is worth buying. Thanks!

The iPad Pro 10.5"-inch model supports USB 3, so it is not the "ancient" USB 2 as you mention.

USB-C only refers to the plug, so it hasn't got anything specifically to do with the USB-C to Lighting cable - you can achieve the same, higher speeds using a USB-A port when using a USB 3 compatible cable and USB 3 capable port.

  • That’s not true. Of course, USB-C refers to the plug, but sadly, it’s the only possible option to reach USB 3 transfer speeds between an iPad and Computer. That’s what I meant by “ancient USB 2.0” - Apple’s Lighning-to-USB-A-cables are still USB 2.0. It’s easy to check, just take a look at the USB-A-connector of those cables, if they were capable of USB 3, they’d need to have extra pins in the connector besides the standard 4 USB 2.0-pins. And they don’t, at least I’ve never seen a standard USB-to-Lightning-cable that did.

  • Well, I meant that it is not "USB-C" as such, but ofcourse the whole chain, including the cable needs to be 3.0 compatible. If you use the relevant cables and adapters, you can achieve the high speeds without having a USB-C port in your computer.

  • From Apple you can use the USB 3 compatible Camera Adapter to get a USB-A port with USB 3 speeds, or you can use a USB 3 lightning cable from a different maker than Apple.

  • Okay, thanks for your efforts. Then it was proably a misunderstanding. I already own the new Apple Camera Adapter with USB 3 support, but that one isn't really helpful, since you can't access external storage with the iPad, besides importing photos. I use it occasionally to hook up an Ethernet adapter to transfer files over my network, but setting this up is always more hassle then a simple USB cable would be, especially when I'm not at home. So, although that adapter is a nice perk, it doesn't really fix the problem...

  • Considered using a USB-A to USB-A cable to use that adapter to hook up to your PC? ;-)
