Kingston's 16GB DataTraveler Locker relies on software locking out a partition. We much prefer this to the common hardware encryption, which first mounts a virtual CD drive and then upon proper authentication shows the data partition. The problem with this? It's invariably Windows only, and more than once has caused some partition headaches even on the operating system of choice.
The software version of Kingston's encryption works by creating an encrypted partition, meaning to create it and see it, you'll still need Windows — but at least you can leave a portion of the drive open for cross-operating-system viewing.
The way the software works is flat-out odd — run it, enter your password and it swaps out your normal partition for the encrypted one, making it appear as if it's the entire drive. There's no way to see both partitions at once.
As a USB 2.0 drive, the DataTraveler Locker isn't the speediest drive of the bunch, as shown by its CrystalDiskMark scores. Still, compared against other USB 2.0 drives as shown here, it puts in a good effort.
