ESP32 Forum

Tried the TinyUSB Mass Storage Device Example on a ESP32-S3 with IDF v5.1.2.
Configured to use internal flash as storage. Though it works fine, its super slow copying files to it.
When I copy a 756k file it took a minute to do it. I know the flash is not that slow because when I copy that same file via TCP to it it does it in 6 seconds.

Is there any way to speed the transfer up?

Try to optimize your code. Get rid of unnecessary delays, loops, or other bottlenecks that might be slowing down the transfer process.
