AMD has acknowledged a Radeon driver bug causing continuous background writes to SSDs on Windows 10 and 11 systems. The issue stems from the AMD External Events Utility, specifically the atieclxx.exe process, which has been recorded writing up to 5 MB/s.
Users report sustained write activity between 0.3 and 5 MB/s, with the highest rate totaling 432 GB daily. While AMD representatives suggest a fix was committed, the latest Adrenalin 26.10.2 driver release notes do not explicitly mention a resolution.
Unchecked writes can reduce SSD lifespan. Temporary fixes include disabling the External Events Utility or Resizable BAR, though these workarounds may negatively impact gaming performance, FreeSync functionality, and the use of Adrenalin software hotkeys.
