If data security is paramount, the DataTraveler BlackBox is the USB flash drive of choice, despite its relatively high cost.

Regardless of whether you need to secure your company's important financial documents or protect your private personal information, the BlackBox provides extreme security and extreme ruggedness in one easy-to-use package.

This drive doesn't provide the myriad options of the Transcend JetFlash 220 but, as a drive dedicated to secure data protection, it's hard to beat.

Kingston's DataTraveler BlackBox is an ultra-secure flash drive for those who carry sensitive files. But unless you're on a government-grade budget, you'll have to choose a cheaper drive.
