Hey All,

This is probably a silly question. but I noticed when I use a WD drive like this , it goes extremely slow when it gets through USB-C at any point. I have test the following:

  • normal Micro B - USB A cable to thunderbolt dock. Dock to Mac through thunderbolt 4 cable
  • Miscro B - USB A cord, with USB-C adapter then plugged directly into mac
both routes give me EXTREMELEY slow read/write speeds. However if I use something like this with the same dock, or adapter, its pretty much full speed. Its just the 2 micro B drives that are barely crawling ..



any thoughts?

That WD drive is a 2.5" mechanical hard disk drive. It's going to be very slow (in modern terms) no matter what interface it has on it.
The USB stick is a solid state flash drive. It'll be 2-3x the speed of a 2.5" mechanical drive easily.

...yes i understand mechanical vs SSD. However it shouldnt be 40MB/s slow. its not on my other computers.
