Two-Year SSD Data Retention Test: Unexpected Results
2025-04-19
TechTuber HTWingNut conducted a two-year experiment testing the long-term data retention of SSDs. Four 128GB SATA SSDs were used, two new and two heavily used (exceeding their rated TBW). After two years, the new SSDs showed data integrity but a significant increase in error correction codes, indicating potential issues; while the used SSDs experienced file corruption and performance degradation. This highlights the risk of data loss in SSDs even when unplugged for extended periods and underscores the importance of regular backups.
