Writing from COM to microSD


#1

Hi there!

I have an device I want to build that needs to capture COM data and write it to the microSD card. I would be reading at a baudrate of 921600, and therefore writing out a max of 11520kB/s. Can The FEZ handle that? I wouldn’t really be doing much processing on the device, I just need to send some commands down the COM at the start and at regular intervals.

Thanks for any information!

We see an average write speed of 200000 bytes/second. This is continuous. If you want to do bursts then you can buffer your data

that was the average. The quality and fragmentation of the media can give different results
