Which Kinds Of Cards Do You Have?

Having one of these devices that can easily attach to your keyring is certainly convenient. You may want something with a bit more versatility, though. Being larger also means additional functions.

The Unitek offers an additional slot that adds CF cards to both the SD and micro-SD cards being readable. If you go for the WARRKY, you gain an additional slot for Sony MS cards, along with three USB 3.0 ports.
