Microsoft debunks claims of SSD failures in Windows, asserting that the recent update did not lead to storage breakdowns.
Microsoft and several SSD manufacturers have been investigating reports of SSD failures following the installation of Windows update KB5063878. However, after thorough investigations, neither Microsoft nor the manufacturers have been able to establish a direct link between the update and SSD failures.
Microsoft has claimed that no customer has reached out directly to its support teams with this same issue. The company has also investigated the matter and found no connection between the August 2022 Windows security update and SSD failures.
Phison, a company that makes SSD controllers, has also denied a document circulating that listed its controllers as being affected by the issue. Phison and Microsoft have not been able to reproduce the SSD issue related to KB5063878. Phison continued testing for 4,500 hours and could not reproduce the SSD issue.
Despite these findings, there are social media posts claiming that drives died after installing KB5063878. It's unclear whether this is a pattern or a coincidence.
Further testing of 21 different SSDs revealed that drives using controllers from other brands were also affected. The issue seems to affect SSDs that handle cache, with models without DRAM and Phison NAND controllers being heavily affected. One user claims the bug affects SSDs under large data writes and high drive usage conditions.
If you are experiencing the same problem, it's advisable to report it to both the drive manufacturer and Microsoft. Phison recommends installing heatsinks on SSDs for users with heavy storage workloads to reduce the chances of thermal throttling.
It's important to monitor SSDs, particularly when writing large files on drives that are more than half full. For up-to-date news, analysis, and reviews on this and other tech-related topics, you can follow Tom's Hardware on Google News or subscribe to the Tom's Hardware newsletter.
Microsoft has concluded that there's no problem with the Windows update. The Western Digital SA510 2TB model tested could not be recovered after SSD failure, but Microsoft maintains that there is no connection between the failed drives and the security update.
In conclusion, while there have been reports of SSD failures after the installation of Windows update KB5063878, neither Microsoft nor SSD manufacturers have been able to establish a direct link between the update and the failures. It's recommended to monitor your SSD and report any issues to the manufacturers.
