My old external hard disk drive somehow got corrupted to the point that I needed to reformat it to get it working again, so I'm in the process of backing up my files again. I recently upgraded my Windows partition from 7 to 10, and the file transfer speeds from the computer's HDD to the external HDD are absolutely abysmal! They were never this bad with Windows 7, and my Linux Mint partition has really screaming file transfer speeds to this drive.

While I understand that moving many small files may bog down file transfer speeds, I don't think they should be this bad, especially when Windows 7 and Linux Mint can move them at speeds well exceeding 20 MB/s. Windows 10 is moving the files at slower than 3 MB/s. I have a hard time accepting that I would have to zip files together in Windows 10 to get acceptable file transfer speeds especially when this was never a problem before.

While I'm guessing the transfer from computer HDD to USB external HDD with Linux is really fast because it's relatively light weight, I can't figure out why Windows 10 is so much slower in this regard when compared to Windows 7. What changed?
 
Solution
Check the cache mode Windows is using on the drive. An update turned caching off, iirc, so that you wouldn't have to eject the drive anymore. .
