I prefer the M-Systems DiskonKey. They are durable, exceptionally fast(many 2.0 keys are compatible, not certified) and have a very good software suite. The password is secure, using a almost impossible to crack encryption method. Some other manufacturers have had issues with this lately. Lexar's passwords were stored using XOR based encryption and could be easily cracked. M-Systems' current generation of keys is solid and has an unusual feature. The data going into the secured partition will be read and written at the same speed as to a non encrypted partition.
