Storage & Preventing Data Loss

SD Cards Are Not (Really) a Storage Medium

The Raspberry Pi 500 uses an SD card as main storage medium. While modern SD cards offer plenty of space, they are by far not a secure storage medium. A potential failure of the SD card and resulting data loss will be a real concern, especially when your applications writing a lot of data on the card — as audio capture typically does.  

There are several steps you can take, to prevent data loss:

1. Using a normal Raspberry Pi 5 with added SSD storage
   
2. Attaching external storage (this might lead to problems, if writing to the device will become too slow)
3. Syncing the files in the background with another devicedevice.

While 1. will make your project sadly a lot more expensive, the second option can be done with Open-Source tools. 

Installing Syncthing

Open Pi-Apps and from the System Management menu choose and install Syncthing.
