Hello,
In my project I want to work with USB drives and SD cards with capacities in gigabytes or terabytes with exFAT.
Does MicroPython supports this?
On which chips/boards?
Could it connect two drives and copy files between then?
In what teoretical speeds?
Can MP support huge flash storages?

Re: Can MP support huge flash storages?
As far as I know no microcontroller running MicroPython supports USB drives. However MicroPython will run on hardware with an underlying OS such as Raspberry Pi boards: you can simply run the Unix build of MP and access any disk visible to the OS.
As for SD cards on microcontrollers I'm not aware of an upper capacity limit.

Some Teensy boards (Teensy 3.6 and 4.1), using Arduino programming, support USB storage.

for Teensy don't yet support USB storage, but it can be implemented.
