SSD manufacturer 'Phison' clears its name after Windows 11 bricking panic — 4,500 hours of testing and zero drive failures

SSD controller manufacturer Phison says it found no evidence of drive failures linked to recent Windows 11 updates.

A recent Windows security update is causing issues with some SSDs, but Phison says it's not related to its controllers.

Earlier this month, I covered reports suggesting that Windows 11 version 24H2 security update KB5063878 was causing certain solid-state drives (SSDs) and hard-disk drives (HDDs) to malfunction. In some rare cases, it seemed like the drives were being completely wiped out, with data becoming unrecoverable.

In other instances, users found that their drive was no longer recognizable until performing a full system restart. Phison, one of the world's largest suppliers of the controllers that these drives require to operate, was named as potentially being the culprit behind the drive failures.

This arose from one user — @Necoru_cat on X — following the testing of 21 different SSDs. Phison was quick to announce that it was investigating the claims. Now, it's returned with proof that its controllers are not to blame for the Windows storage issues.
