I’ve been playing around with SanDisk's new 4GB Cruzer Titanium Plus USB Flash drive, which includes a little extra peace of mind for road warriors. All files copied to the thumb drive are automatically backed up online to a password-protected storage site. 

Therefore, if this pinky-sized drive is lost or stolen or if files are accidentally deleted, you can always access those files through your 256-bit encrypted account. If your computer is offline when files are copied to the drive, the automated backup will take place the next time the PC has an Internet connection.

Similar to past products, the gold-colored Cruzer Titanium Plus offers a metal, crush-resistant body to further protect your data. It works well, but I have two beefs: There are no 8GB or 16GB models yet, and the free online storage only lasts six months. After that, it's $29.99 per year. This is a shame, as there are many free online backup services, such as MozyHome Free’s 2GB a month or Microsoft’s Windows Live SkyDrive’s 5GB a month.
