I had to return my Delkin USB 3.0 reader (Model DDREADER-42) because it would not reliably recognize the new 95MB/s Sandisk cards. (SanDisk Extreme Pro® SDHC™ UHS-I Memory Card - 8GB SDSDXPA-008G-A75). I returned it to the store and purchased a Sandisk Imagemate Model SDDR-289-A20 to replace it.
Plugged into the USB 3.0 port of my computer and using Nikon Transfer 2 as the transfer program, I was able to move 100 12-bit RAW files (average size or around 14.5 MB each) in just under 23 seconds. I timed the transfer from when I first clicked the transfer button until the transfer queue read 0.
While some people are reporting only minimal speed increases from the card and USB 3.0 readers, my experience is quite different.
