Neither internal testing nor telemetry data indicated an increase in disk failure rates or file corruption related to the update. Additionally, Microsoft customer support teams reported no complaints that align with the alleged SSD problems.
This investigation was prompted by several users who reported sudden SSD failures after installing the KB5063878 update. The earliest report came from a Japanese user on social media platform X, followed by similar accounts worldwide. Some users described severe issues, such as their PCs freezing, crashing, or blue screens appearing. Often after transferring large amounts of data to SSDs that were already over 60% full.

Taiwanese memory supplier Phison also joined the investigation, logging 4,500 hours of cumulative testing without encountering any failures linked to the update. Phison confirmed no partners or customers reported issues affecting their drives due to this Windows patch.

What Users Should Know About the Windows 11 Update and SSD Safety
The reports around KB5063878 highlighted a potential risk for SSDs during high-volume data transfers, particularly when the drive was already significantly filled.

Despite these accounts, Microsoft’s investigation and partner testing have not verified the issue. The company emphasized that their telemetry data and support channels have not seen evidence of widespread disk corruption or failure connected to this update.
Users should note that SSD failures can result from a variety of causes, including hardware faults, driver conflicts, or other software issues unrelated to Windows updates. If experiencing repeated problems, users should consult their device manufacturers or IT support for diagnostics.
For those uneasy about the update, Microsoft offers a rollback option allowing users to uninstall KB5063878. This step can provide temporary peace of mind while continuing to monitor official channels for new information.
