Just like the title says, for some reason my transfer speeds are slower with the same drive plugged into my 3.0 port compared to my 2.0 port. The drive I am using for the test is a SanDisk USB 2.0 with the factory FAT32 format. Does this make sense? I am seeing a difference of about 7 MB/sec. Nothing is plugged into the other ports on any of the controllers during the test.
