The price of SanDisk Cruzer Titanium 1GB is equivalent to Kingston microSD 1GB. I bought the former as it comes with Avast! Antivirus U3 Edition and CruzerSync. The latter U3 software allows users to easily and securely (AES 128-bit encryption) access, edit and restore ALL their personal files (productivity documents, audio and video files, bookmarks etc.) and Outlook data (emails, attachments, calendar, contacts, notes, tasks) at anytime from any computer in the world.
There is no need to install any software as it is already installed on the flash drive. You'll need a computer running Windows 2000 or XP to use the U3 software. After updating online, the trial license for Avast! Antivirus is 2 months only.
However, you can also download free license of Cruzer PocketCache for Titanium and CruzerLock 2 from SanDisk. Cruzer PocketCache enables you to perform regular and repeated backup of PC files and directories, typically for months, onto a single Titanium flash drive. CruzerLock is a security application designed to protect your personal data files. Your individual files can be encrypted / decrypted to prevent unauthorized viewing.
