As stated on August 18, Phison was made aware of the KB5063878 and KB5062660 updates on Windows 11 that potentially impacted several storage devices, including some supported by Phison. In response, Phison dedicated over 4,500 cumulative testing hours to the drives reported as potentially impacted and conducted more than 2,200 test cycles. We were unable to reproduce the reported issue, and no partners or customers have reported that the issue affected 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.
