Phison denies that Windows 11 update will damage SSD: 4500 hours test still cannot be reproduced, users are advised to use a radiator

Recently, the SSD "disk drop" incident caused by the Windows 11 update has caused a lot of noise.Phison, a well-known SSD master control manufacturer, pointed out in its latest statement that despite 4,500 hours of testing, the problem was still unable to be reproduced.

Not long ago, Microsoft pushed Windows 11 update KB5063878, which was originally intended to solve the problem of reduced game performance, but unexpectedly caused large-scale SSD failures.

Some Windows 11 users found after installation that when the computer transferred large-capacity files, the SSD may "suddenly disappear" and cannot be restored even after restarting, resulting in data loss.

In this incident, the one that attracted the most attention was Phison, whose controllers are widely used in a variety of consumer and commercial SSDs.

"Phison Electronics has accumulated more than 4,500 hours of testing and conducted more than 2,200 test cycles on drives reported to be potentially affected," the company told Tom's Hardware in a statement. "We have been unable to reproduce the reported issue, and no partners or customers have reported this issue affecting their drives."

Initially, reports suggested that drives using Phison controllers might be the most affected. Phison acknowledged the issue early on and even issued a statement to Tom's Hardware confirming that some of their hard drives may have been affected:

"Phison Electronics recently learned about the industry-wide impact of the 'KB5063878' and 'KB5062660' updates on Windows 11, which may affect multiple storage devices, including some Phison Electronics supported devices. Currently, we and our partners are investigating products that may be affected."

However, after testing, Phison Electronics concluded that the problem may be a false alarm. Although Phison categorically denied the SSD failure reports, the company said they remain committed to supporting customers should any issues occur.

The company also recommends that users use a heat sink on high-performance hard drives, as overheating may cause SSD performance to degrade.

"We continue to advise users that for prolonged workloads, such as transferring large files or decompressing large files, ensure that the storage device uses a suitable heat sink or thermal pad. This helps maintain optimal operating temperatures and ensures continued performance."
