I like to work within the boundaries of the “Vanilla Pi3” but the max_usb_current=1 will not void warranty right? The USB stick works as one would expect, it mounts and everything it is just very slow (currently copying a PSX .pbp file at 1.8mbyte per second) while I am sure the internal SD could hit 8 to 10. I am just curious what causes this. I would expect a Sandisk USB3 stick to not be the bottleneck and that the max USB2 throughput would, if anything, be the culprit.
