Codex is continuously writing a large amount of data to the local SQLite feedback log database:

On their machine, after about 21 days of uptime, the main SSD has written about 37 TB
On a 1 TB SSD, that is about 640 full-drive writes per year
TRACE alone is about 70.7% of retained bytes. codex_otel.log_only + codex_otel.trace_safe add another 25.3%
About 36,211 rows were inserted in 15 seconds, while retained row count stayed flat
