Try a USB 2.x port. My external USB 3.0 HDDs, including two segates, are fine on USB 2, though USB doesn't do the headline speeds.
Also check the SMART diagnostics of the internal drive.
Also set Windows Defender and/or any other AV to be purely "on demand".
Loads of very small drives ARE very much slower to copy for two main reasons compared to a very large file:
1) The source files may be all over the disc but the copy is by directory, not disc location.
2) The destination has to create the directory entries and edit the file chain. The exact destination partition format affects the speed of this.
I'm not sure how loads of small files affects the destination RAM Cache. Likely it's quickly full with a load of small files. Also writing may start at the inside "track"/"cylinders of the disk and can be up to x4 faster, or more at the outer edge because modern HDDs use a hidden variable sectors per track/cylinder to maximise storage as the data rate can be higher as you move outwards due to constant rotational speed. CDs earlier increased storage capacity by running a single track at constant linear velocity, which is fine for sequential use. Obviously an HDD needs to be at constant rotational speed to maximise random access performance.
