Originally posted by barondla Good to know. The laptop is less than a year old and always getting Dell updates, so it should be fine. The laptop has usb 3 ports on its left side and usb 2 and SD card slot on the right. Should probably compare the built in reader to an external 3.0 to see if it achieves 3.0 transfer speed.
The desk top is older and already uses an external 3.0 reader.

Unless I'm missing reading your post, it seems that you have all you need to test it yourself. Move your external usb3 reader from the desktop to the laptop and compare file transfer on the usb2 to the usb3.
I definitely see a difference in transfer times on my usb3 compared to my usb2. I have 95 MB/s U3 class 10 SD cards so they make use of the faster capability of the reader.
By the way, having the U3 cards are not necessary for the camera's write speed, as the internal camera write to memory is relatively slow. I could test no difference with 40MB/s cards in camera v. the 95 MB/s cards.
