Hi Sean, The Casperised Red Pitaya is running a Linux OS (Debian/Ubuntu), together, with tcpborphserver on the PS. Tcpborphserver interacts with casperfpga on your host PC for comms. I am able to ssh into the Red Pitaya and copy files across using scp. This is all stored on the SD card, so it should easily be possible to store data on the SD card. I am not sure what rate.
Check out: https://casper-toolflow.readthedocs.io/projects/tutorials/en/latest/tutorials/redpitaya/red_pitaya_setup.html?highlight=SD and https://redpitaya.readthedocs.io/en/latest/developerGuide/os/debian.html I have also used a Raspberry Pi for this type of application in the past and it works well for data logging. Good luck!
