Phison confirmed that the SSD failures and corruption issues linked to Windows 11 updates were caused by the use of engineering preview firmware in testing, not the final consumer firmware, and that the failures do not occur with retail versions of the drives.
The recent Windows 11 24H2 update caused SSD problems, but the root cause appears to be pre-release engineering firmware used in some SSDs, not the final production firmware. Users with retail SSDs should be unaffected, but updating firmware and backing up data is recommended for those experiencing issues.
Phison conducted extensive testing on SSDs affected by Windows 11 updates KB5063878 and KB5062660 but was unable to reproduce the corruption issues reported by users. The company suggests that the problem may be on the user side, related to thermal management during sustained workloads, and recommends using heatsinks or heat spreaders to prevent potential damage.
Phison has conducted over 4,500 hours of testing on its SSDs following reports that Windows 11 updates ('KB5063878' and 'KB5062660') were bricking drives. The company found no issues during extensive testing and has dismissed these reports as false, emphasizing the importance of proper cooling and thermal management for SSD longevity. They also highlighted potential misinformation and urged users to follow best practices for high-performance storage devices.
Phison has issued a statement denying the circulation of falsified documents claiming their controllers are prone to a Windows 11 SSD bug, clarifying that the documents are fake and that the issue affects multiple vendors and storage types, not just Phison. The company is working with Microsoft to address the problem and is investigating the false claims, which may be an attempt by competitors to create panic.
