PowerEdge: Micron 5x00 Series solid state drive Performance Degradation after 65,535 POH

Summary: Micron 5x00 Series SSDs may experience read/write performance degradation after reaching approximately 65,535 power-on hours (POH), which equates to roughly 7.5 years of operation. This issue affects performance only and does not result in data loss or drive failure. ...

Symptoms

Customers may report reduced SSD performance on systems using Micron 5x00 Series drives that have accumulated ~65,535 POH which equates to roughly 7.5 years of operation

  • The drive remains functional and accessible.
  • No data integrity or reliability risks have been identified.

Cause

The issue is caused by an internal firmware limitation:

  • The SSD uses a 16-bit counter to track workload log entries.
  • This counter reaches its maximum value at 65,535 hours.
  • Once this threshold is reached, the firmware begins generating continuous debug log messages.
  • This excessive logging consumes controller CPU resources, reducing the drive’s ability to process I/O requests efficiently.
As a result, read and write performance may degrade noticeably.

Resolution

Micron has released updated firmware that mitigates this issue.

 

  • The minimum firmware version containing the fix for Micron 5100 M.2 drives is L013.
  • The minimum firmware version containing the fix for Micron 5100 U.2 drives is L013.
  • The minimum firmware version containing the fix for Micron 5200 U.2 drives is F006.
 

The firmware packages are available for download from Dell Support.
