Hello, I have a WD my passport 4tb.
It works great. But the software that was installed along with the disk, and in particular WDDriveService.exe, conflicts with the samsung t5 portable ssd disk.
When WDDriveService.exe is running, samsung t5 is very slow. The speed of writing and reading drops by 2-3 seconds to almost zero.
If you close WDDriveService.exe, then samsung t5 starts working as expected, without speed breaks.
Please correct this in the next update. thank
