After updating several machines from Windows 10 to Windows 11 users have noticed a significant degradation on Disk Random Write speed. This is quite noticeable with NVMe SSDs benchmarks, it also seems to affect SATA SSDs even if it is not as significant. See 3 samples below with 3 different devices on Windows 10 and Windows 11:

Windows 10 19043.1165 NVMe SSD SK Hynix:

Windows 11 22000.160 NVMe SSD SK Hynix:

Windows 10 19043.1165 SATA SSD ADATA SU800:

Windows 11 22000.160 SATA SSD ADATA SU800:

Windows 10 19043.1165 Samsung NVMe SSD MZVLW:

Windows 11 22000.160 Samsung NVMe SSD MZVLW:

    Hi fg2001,

    As you already know I also have a significant degradation on Disk Random Write speed on the Samsung 970 EVO Plus NVMe M.2 1tb primary OS SSD from my previous posts concerning Windows 11. There far I upvoted/Found Helpful your New discussion post.

    Hopefully and I'm sure they will find a fix for this Hiccup soon. Sorry I couldn't provide my CrystalDiskMarks here in the New discussion but I have since deleted them from my Unit.

    Thank-You for Posting This Information perhaps it will help others that are facing the same Hiccup as us.

    Have you tested with .168?

    I haven't run a CrystalDiskMark yet with the new 22000.168 but I'd run it now.
