SanDisk is my favorite SD card brand. Very satisfied with the memory card reader "Everything but Stromboli Multi Slot Card Reader". Used this to backup my OS. This usually requires a flash drive, but this reader has allowed me to use a micro SD card. IMHO a much better option. The reader can be used with any size micro SD card, which is very convenient. I highly recommend this option over a standard flash drive that is too bulky and sticks out of the USB port. SD cards are what you need.
