phison firmware

About this tag
The phison firmware tag covers discussions about Phison SSD firmware, particularly pre-release engineering firmware that was linked to NVMe drive failures in mid-2025. Community reports and headlines initially blamed Windows 11 cumulative update KB5063878 for bricking SSDs, but joint investigations by Microsoft and Phison found no reproducible link between the update and mass failures. Instead, the root cause was traced to pre-release engineering firmware present on a small subset of drives. Topics include troubleshooting NVMe disappearances, sustained write performance issues, and the coordinated testing that exonerated the Windows update.
