SD as MSC write speed for SF3W
Posted: Thu Apr 22, 2021 1:20 am
Hi,
I have a Pyboard D SF3W. I am setting the SD (class 10) to be visible to the host computer as USB mass storage. For file copies to the SD I am getting slightly over 1MB/s transfer speeds.
Is this the expected speed? Anything I can do to increase it?
This is how I am mounting the SD

Code: Select all
uos.mount(pyb.SDCard(), '/sd')
pyb.usb_mode('MSC', msc=(pyb.SDCard(),), high_speed=True)
