Windows 10 users who have decided to hold off on upgrading to the latest version of Microsoft’s hugely popular OS have probably made the right decision, as the problems for Windows 11 appear to be piling up.
The latest relates to SSD performance; some users on the web are reporting that their NVMe drives are operating worse on Windows 11. More specifically, the OS seems to be crippling either the IOPS or read/write performance of various drives such as Samsung’s 970 EVO Plus and WD SN520.
From Mussels84, showing reduced writes on Windows 11 vs. Windows 10:
From MahtiDruidi, who experienced crippled 4K write speeds:
From MJ_JasonM, highlighting reduced performance in the RND 4K Q32 T16 test:
A Microsoft employee had confirmed that the company would be looking into the problem a few months ago. An update released in November (KB5007262) includes a supposed fix for SSD performance, but users still seem to be experiencing degraded speeds.
“Addresses an issue that affects the performance of all disks (NVMe, SSD, hardisk) on Windows 11 by performing unnecessary actions each time a write operation occurs,” Microsoft wrote. “This issue occurs only when the NTFS USN journal is enabled. Note, the USN journal is always enabled on the C: disk.”
