Does an SSD Tweaker affect card readers? I tried to copy files from a regular HD (in a machine that has an SSD boot drive and tweaked using an SSD tweaker) to a microsd card inserted in a high-quality card reader, and the file copy slows down frequently to 0. Also, the system freezes momentarily during copying, with some windows "not responding." It doesn't matter whether I use USB 2 or 3. I tried a laptop with a regular HD as the boot drive and an internal card reader, and the file copying ran smoothly. I connected the external card reader, and the copying ran smoothly as well.
