The system:
Dell XPS 17 with USB 3.0 ports
Tested that specific reader on all USB 2 and USB 3 ports on this system.
Also tested a USB 2 reader in the USB 3 port, and che speed increase is comparable to the new reader's tests (i.e. barely anything)...
The results...
Reader issue? Don't have another system to test on
System/Port issue? Checked BIOS, installed various drivers, nothing makes a difference
Cards? The Sandisk are pretty much where I expected them to be, but the Transcend are falling short of expectations... I also tested multiple Transcend 400X cards in both USB3 ports - no substantial differences...
