That’s six data sources writing continuously. I needed a database that: survives a power cut without corrupting, handles thousands of small inserts per hour, doesn’t need a separate server process, and lets me keep years of rollups on a single SD card. After parallel-running it against my old RRDtool setup, I landed on SQLite in WAL mode.
