GoKawiilExperts warn thumb drives are unreliable for long-term data storage
Flash drives face multiple risks including physical loss, a finite number of write cycles before failure, and 'bit rot,' where stored electrical charges degrade over time and corrupt data. Unlike SSDs, thumb drives can't use TRIM commands to recover worn storage space, and their connectors or controller chips can fail due to impacts, corrosion, or humidity.
GoKawiil's interpretation of the reporting above, not reported fact.
The cumulative risks suggest that thumb drives, despite their convenience, are not dependable for preserving important files over many years. This could push users and organizations toward redundant backup strategies, such as cloud storage or multiple physical copies, to avoid silent data loss from bit rot or sudden drive failure.
- Flash drives have a limited number of write cycles, typically 10,000 to 100,000.
- Bit rot can silently corrupt stored data over time due to charge loss in memory cells.
- Physical components like connectors and controller chips can fail from impacts, corrosion, or moisture.
