Windows 11 Update Blamed for SSD Failures, but Phison Can't Reproduce Issue

Phison and Microsoft found no link between Windows 11 security updates and SSD failures after 4,500 testing hours, advising caution with heavy workloads on storage devices.

  • Phison recently said it is monitoring reports and working with partners while Microsoft found no evidence that Windows 11 updates KB5063878 and KB5062660 corrupt consumer SSDs.
  • On August 14, X user Necoru_cat posted test results on 21 drives, linking Windows 11 version 24H2 KB5063878 to failures during large write operations.
  • Phison's lab testing showed 4,500 cumulative testing hours and more than 2,200 test cycles failed to reproduce SSD failures, recommending heatsink or thermal pad use for extended workloads.
  • Microsoft issued a service alert noting it could not reproduce the problem and asked for detailed feedback, despite users reporting bricked drives including one WD Blue SA510.
  • Phison and Microsoft will continue monitoring reports and advising partners as third-party outlets and fleet managers also fail to replicate the SSD issue, prolonging uncertainty.
