This is Phison’s official statement to partners regarding the recent media reports about a Microsoft issue that potentially corrupts storage devices.
Phison has recently been made aware of the industry-wide effects of the 'KB5063878' and ‘KB5062660’ updates on Windows 11 that potentially impacted several storage devices, including some supported by Phison. We understand the disruption this may have caused and promptly engaged industry stakeholders to review.
We are steadfast in our commitment to product integrity and the success of our partners and end users. At this time, the controllers that may have been affected are under review, and we do not recommend adjustments to product distribution. We will continue to provide real-time updates and advisories to partners who may have been impacted. For any questions, please contact your sales representative.
To investigate, Phison dedicated over 4,500 cumulative testing hours across the drives reported as potentially impacted and conducted over 2200 test cycles. We were not able to reproduce the reported issue and no partners or customers have reported that the issue impacted their drives at this time. Phison remains committed to the highest standards of reliability and continues to closely monitor the situation in collaboration with our industry partners.
Best Practices for End Users
While our validation testing has not identified any concerns related to these Windows 11 updates, we have shared industry best practices to support high-performance storage devices. We continue to advise that for extended workloads, such as when transferring large files or decompressing large archives, users ensure a proper heatsink or thermal pad is utilized with the storage device. This helps maintain optimal operating temperatures, reduces the likelihood of thermal throttling and ensures sustained performance.
