All iPads New "Files" Feature in iOS13

[hjb]

There are three things I want to do, so I tried them with various adapters. I don't completely understand what's happening, so I thought I'd reach out to the community.

1. Copy videos from an SD card into my lightning-based iPad 9.7 Pro. I bought Apple's Lightning to SD Camera Reader, plugged it in, inserted a 64GB card, and started copying. It worked.

2. Copy the files from the SD card into Dropbox or iCloud. Yes, after I did #1, I was able to do this successfully.

3. Copy files either directly from the SD card to a USB thumb drive or from SD to iPad to USB thumb drive. I bought a lightning dongle attached to a white box with a USB, SD, miniSD and (for pass through power) lighting slot. I can read the SD card, same as with the Apple adapter, but the USB draws too much power to allow a USB drive (can somebody explain this to me?)

So: what should I know about option 3--am I asking my iPad just to do too much? Is that why these adapters seem to come only from Amazon sellers without brand names? Please help with a clear explanation as I am new to this.

Should I return the Chinese adapter? (I have another similar product on the way.)

Thanks!
HB

Files can't deal with videos > 4.5GB on external storage

Using 2018 iPad Pro with 13.1. I've found that with mp4's greater than around 4.5GB on external storage that the Files app can't play the video itself nor does it share it well with other video apps (nPlayer, Infuse, VLC). If under 4.5GB, Files can play the video and share it correctly. Video...

What you need is a powered USB hub.
You connect the power-hungry devices to the hub and then the powered hub to the iPad. Just make sure the hub can support all the devices you want running simulatenously.


Lightining port iPads generally do not provide enough power over the port alone to support most sd card readers, let alone drives or hubs (or even some pendrives).

For my iPad 5 I've been using a USB3 usb+power(lightning) dongle from Apple, which is somewhat equivalent to your hub

Lightning to USB 3 Camera Adapter - Apple

However, just checked and I have not been able to make it to run HDDs or more power hungry usb devices. Even with a more powerful charger than the standard iPad 10W one serving the "pass through" power. My guess is that this has sth to do with the power configuration of the Apple dongle and your multi-reader. That said, you might want to give it a shot and use a more powerful charger to see if it supports your devices.

Anyways, the powered hub method seems to be working, for me at least. Still, I suspect you'll get really slow transfers when using ipad as the device handling the transfers, the 9,7 pro still operates at USB2 speeds. When transferring data via ipad to different USB devices, you'll effectively cut that speed in half, so realistically, I would not expect anything more than 15MB/s and given the bugs in Files app, much less than that. Not really a promising perspective, unless you have small files... and not many of them.
