I purchased Lightning to USB 3 Camera Adapter yesterday and do a simple speed test with my 2017 iPad Pro 10.5. (using Samsung T3 Portable SSD 1TB)
The result is surprising me.
I expected the speed will be at 100-200MB/s but the real speed is nearly identical to desktop PC.

The read speed is around 390MB/s and write speed is around 350MB/s.

And the performance is very stable.

It's much faster than iPhone 11 which is USB 2.0 ( and even iPhone 14 Pro series still using usb 2.0)

Wish apple can bring usb 3 support on next year's iPhone 15. (And using usb-c would be better)

It's not only speed, it's also power. Lightning 2.0 cannot power HDDs and some power hungry SSDs (typically sandisk from 1GB and up). While Lighting 3.0 (which started with the 2015 iPad pro, but not the 9.7) can power any drive.

It seems that Lightning to USB 3 Camera Adapter is the only lightning accessory with usb 3.0 support...
