Recent Windows 11 update isn't behind gaming SSD failures, says Microsoft

Microsoft has responded to reports that a recent Windows 11 security update has caused gaming SSDs to fail. According to the company, a “thorough investigation” left the company in no doubt that its recent KB5063878 security update isn’t the cause behind these mysterious drive failures.

Despite those earlier Windows 11 SSD failure reports, Microsoft hasn’t been able to replicate the issue on its own Windows 11 PCs. That leaves plenty of unanswered questions, especially with regards to identifying the cause behind the issue. While plenty of drives have so far not been listed as affected, such as Samsung 990 Pro and WD Black SN7100 that you can find on our best gaming SSD guide, there's still cause for concern until the reason for the problem is resolved.
