The fastest drive in this roundup tested nearly four times slower than two nonsecure USB 3.0 flash drives we included for comparison. In fact, none of the manufacturers reviewed here expect to release a USB 3.0 model until at least late this year. Unfortunately, current secure flash drive performance doesn’t match security, largely because they’re mired in the USB 2.0 past. The Apricorn Aegis Secure Key is being processed for Level 3 certification, though it is not yet certified. The Imation Defender F200 ratchets that up to Level 3.

Three of the units–the Kingston DataTraveler 4000 Managed, the Kanguru Defender 2000, and the CMS CE-Secure Vault FIPS–are certified to Level 2 of the government’s FIPS 140-2 security standard.

The results? As far as security is concerned, it’s all systems go. To get the skinny on the state-of-the-art in secure flash drives, we took five hardware-encrypted drives for test spins. You’ll pay a premium for the integrated security, but you can’t put a price on the peace of mind you get by knowing that your data is locked down. And what better than something that hides easily within a pocket? Secure flash drives that are only about the size of a small cigarette lighter feature robust hardware security to make them super secure. If you’re physically transporting data you don’t want other people to see, you should be doing it on secure media.
