With the upcoming optional KB5007262 update, Microsoft finally fixes a frustrating Windows 11 bug which significantly reduced the random write speeds of both SSDs as well as conventional hard drives.

"These fairly wide-spread SSD performance issues are apparently caused by the NTFS USN journal mode, which Windows 11 automatically activates for drives assigned to the letter C."
Is the file system's journaling feature itself is the problem, and the fix turns off journaling? That would be bad! Or was journaling badly implemented?
