Windows 10: Copying files speed from one drive to another decreases after update to 22H2

Hello,I noticed that copying files from one drive to another became very slow and sluggish after upgrading from Windows 11 to version 22H2. Before the update, the speed was always above 100MB/s, now it stops at 0 for a few seconds and never exceeds 50MB/s. It became a real nightmare.To confirm it was not hardware issues, I reinstalled Windows 11 22000.1042, the problem disappeared, when I went back to upgrade to Windows 11 Version 22H2 22621.607 the speed problem returned.CPU: 12-Core AMD Ryzen 9 3900X, 4264 MHz 43.25 x 99Motherboard: Asus ROG Strix X570-E GamingMemory DDR4: 32676 MBGra

File copying speed questions

Quite easily USB flash storage pen drive speed can be influenced by type of HDD or SSD inside the machine (both the physical device itself, the controller they are connected to via motherboard in terms of hardware, firmware and drivers wise), the USB controller on the particular machine (which includes hardware, firmware and drivers) and lastly there is the performance of the USB pen drive itself.

Normally you would get good USB pen drive performance from machines with the latest hardware, updated with latest firmware and software, and when the machine is used with a new USB pen drive with good performance specifications.

As for speed fluctuations the first part of the process is often done with temporary burst speed and drops down to a sustained speed, and transfer speeds can vary with different types of files such as copying a single file (often fast), multiple files (normally take longer and can take longer than copying multiple files, which are collectively the same size, as a single file) or a compressed files with either a single or multiple files inside (normally faster than uncompressed files of the same set of files which were compress into the compressed archive file).

 

File copying speed questions

Hello,
a few days ago while copying a file to my flash drive, and painfully watching the speed at 2Mb\s this subject kinda intrigued me (especially because my first thought was that something is wrong with my drive*Eek! )

So anyway, say I'd like to copy a file from Drive A to B. From the little I know, copying speed should be determined by drive's A read speed, drive's B write speed, and the connection speed(usb 2\3, sata etc)?Essentially the copying speed being the slowest? Like in my case the write speed of my old USB drive?

Also why does the copy speed fluctuate? For example for my flash drive starts copying at about 6mb\s, and then for the most part stays at 2mb\s.Same happens with my SSD and HDD but thankfully at MUCH MUCH higher speeds *Respect :respect:
