SD and MicroSD cards are great, but not all computers have slots for them, and even laptops that do typically only have one. Plus, if you only have a MicroSD card, then you need an additional adapter to use it with the SD card reader anyway.
The Anker USB 3.0 SD card reader can make your life a little easier. It has both SD and MicroSD card slots that let you read and write both simultaneously on any computer.
