Amacom's Data Locker is definitely a secure drive and would be a good option for business users transferring confidential data between locations. The downside is that it's pricey and faces stiff competition from Lenovo's ThinkPad USB Portable Secure Hard Drive. Then again, Lenovo's offering maxes out at 320GB (135) and doesn't have a built-in display. The Data Locker isn't the quickest drive on the block either, claiming read and write speeds of 34MB/s and 23MBs respectively, but its number one priority is protecting your data. With features to protect against brute force attacks, one-touch drive erase for rapid re-deployment, and unattended auto lock function, the Data Locker is a versatile all-rounder.
