Packaging:

SanDisk's Extreme USB 3.0 flash drive comes in a small, black box. Along with a picture of the drive, the front advertises many of its key features including its capacity, rated speeds, password protection and 2GB of free online storage. The back of the box provides a bit more information regarding the Extreme's features, capabilities and supported operating systems.

Physical Features:

While far from being the smallest flash drive in SanDisk's lineup, the Extreme is relatively compact for a USB 3.0 flash drive. With the USB connector retracted, the drive measures 2.79" (70.87mm) long, 0.84" (21.34mm) wide and 0.45" (11.43mm) thick.

The body of the Extreme is constructed of a lightweight, black plastic. While the strip in the middle has a glossy finish, the sides and bottom have a rougher, matte finish which makes it a little easier to hang onto the drive. The Extreme also has a hole on the end so that it can be attached to your key ring.

The Extreme's USB connector is exposed using a sliding mechanism that can be manipulated with your thumb. This sliding mechanism is spring assisted and is one of the smoothest I have seen. There is also a LED underneath the mechanism which lights up blue whenever the drive is transmitting or receiving data or is in the identification process.
