★★★★★ Kingston Card Reader USB 3.0 Review and Basic Speed Test - Slower than using internal reader?

I use this card reader to copy 4k video files from SD cards and micro SD cards onto my iMac.
It's pretty fast, plugged straight into my USB 3.0 input, but I wanted to see if there would be any significant speed reduction. After all, I copy a ton of files, and I really don't want to slow down my workflow (I'm sure you can relate in a way, if you're even reading this review). ;)
I wanted to see if there would be any difference in speed transferring (1/2 expecting the card reader to be *slightly* slower than plugging a card straight into my computer), but alas... zero speed slow down.

Hope this helps!
