Stock standard for USB 3.0 write speeds.

 

Most USB 3.0 flash disks run at these speeds. I had to go searching to find something with a higher write speed :\

Seems you are getting exactly the speeds you should be getting.

They're probably talking about the raw bandwidth that could be achieved, not taking into account overhead from the USB protocols.

If they call for specs of up to 22.. And your seeing 19 when your doing a copy of lots of files vs just 1 large file I would say your rocking. What kind of speed do you get when just doing write of 1 larger file?

As BudMan said, you're trying to copy 29k files, so 19MB/s is pretty good. Also, that 22MB listed is just some max determined by their internal tests or theoretical max based on the chips' specs.
