The Kingston 512 MegaByte DataTraveler Secure Flashdrive is on of my most used flashdrives. Having owned this one for many years, I have not been disappointed even once with its design nor its functionality. It is built within a rugged metal frame lined with tough plastic along its edges.
While now a days flashdrives come in the gigabytes, most are not built to handle accidental drops on the floor for instance.
The Kingston 512 MegaByte DataTraveler Secure Flashdrive also comes with an activity light, which illuminates when the flashdrive is busy.
To round out the list of features, an added key loop allows you to carry this wonderfully built device with you where every you may go.
