One thing I don't like is the large removable sleeve used to protect the finger scanner. I like USB drives that slide the body out or have flip-out hinges. That way, there's no cover to lose.

I don't think it's uncommon for people to in desk drawers, in the pockets of clothing headed for the wash, in car seats or under couch cushions. I've lost more than my share of flash drives to absentmindedness over the past several years, so I want any USB drive I own to have excellent security -- but still be simple to use. This drive absolutely fulfills that need.

The Defender F200 defends against unauthorized data access with two-factor identity authentication -- in other words, it demands two passwords -- and the aforementioned biometric finger scanner. The nice thing about this drive is that you can choose to use the security measures or eliminate the ones you don't want. For example, I chose to use only the fingerprint reader on my evaluation unit.

I've reviewed , and while I don't prefer them over simple password encryption, there are some obvious advantages, the main one being that you don't have to remember a password. Also, no one's going to be able to duplicate your fingerprint unless he goes to the trouble of hacking off your finger. A hacker (no pun intended) can always attempt to guess a password and will sometimes succeed.
