I need to make a device that is very portable that can take SD card and Copy all the files to another in a short amount of time. I do tons of Video and use Micro SD alot because of the portability. Can I make a Pi based product that will take an SD or USB drive and copy it to a Portable SSD? I dont mind having or not having a display. I would like to have a button to push to start and a LED or LCD that can tell me when its done. I figured there should be a product for it already but i havent seen one. Just trying to see if its possible before getting too far in.
