The DataTraveler Exodia M features a moving cap design that protects the USB Type-A connector when not in use. The cap is also color coded depending on the storage capacity. Since this is a 64GB model, it's blue. Other capacity models will have different colors, such as red, black, and teal, making it easier to determine which flash drive you need at a glance. It also has a loop at the end so you can easily attach it to key rings. This makes it easier to transport as well as keep track of so you don't lose it.
