Codex Logging Bug Wrote 37TB in 21 Days, Raising Concerns Over Shortened SSD Lifespan

·2026.06.23 09:04

Key point

A logging bug in Codex was confirmed to have written 37TB over 21 days, potentially accelerating SSD wear.

Details

A bug was discovered in which Codex continuously writes large amounts of data to a local SQLite feedback log DB. In one user's environment, after 21 days of operation, approximately 37TB was written to the main SSD.

Converting this rate to an annual basis amounts to roughly 640TB. For a 1TB-capacity SSD, this translates to 640 full writes per year. This level could quickly exceed the endurance limits of some consumer SSDs.
