Hi, I'm trying to find a solution to transferring footage shot on a drone (64GB exFAT microSD) to an external hard drive while on the road. Power supply is a 12v motorbike battery with a 12v cigarette adapter and USB.
First question: Is it possible to power it all? I was thinking USB power to hard drive as the Pi won't supply enough power. Then power the Pi (and 3.5" screen) through another adapter.
Two: Will the Pi recognise the 64GB exFAT microSD? What will the external hard drive be formatted as?
Three: I can use a Pi 2 model B, would it be much faster using the Pi 3? Any idea how long to transfer a full 64GB card?
Thanks!

exFAT is just another FAT and Linux appears to handle every FAT. I have used a 256 GB memory stick that would be exFAT.
A hard disk is usually NTFS because that is better than FAT.
Pi 2 and 3 will most likely be limited to USB 2 speed, around 35 megabytes per second. Read speeds on memory cards are usually good, probably 20 MB/s or better. Write speeds on modern disks are usually faster than USB 2.
When you are transferring many small files, you get about half the transfer speed of larger files.

You will need the output from 1 or 2 USB 2 ports (or 1 USB 3 port) for the Pi Zero and 2 USB 2 ports (1 USB 3 port) for the 2.5" disk.
You will need the output of several USB 2 ports for the 5 volt supply to a 3.5" disk plus regulated 12 volts. Look at the SATA spec and your disk specs.

You realise it is illegal to drive a car while operating a Pi. Oh, you are on a motorbike. Go for it. Pi in one hand. Disk in the other. Leaning to control steering.
