The power requirement was already over the common USB spec of 2.5 Watts at times so no to all your questions.
How I do such transfers was with a WiFi HDD.
Your concern about transfer rate and more has me wondering if you are on the right machine.

Unfortunately, not all are going to connect to this tablet. After studying all available information, I found it a science connect through OTG the medium of this type. It's a cable, or hdd type or other problem. I wouldn't ask here, if I didn't know that it is possible. Some time ago I had the opportunity to try one 2.5" hdd, which normally go there. I don't remember what type and brand it was, so I ask. Does anyone have this tablet and run with it mechanical disk without external power?
Or as an option to transfer data every day? With reasonable transfer rate and practical use?
thanks for the tip
