Lexar Media is launching flash-based, backup drives, the Lexar Echo SE and Lexar Echo ZE, designed to protect netbook and notebook computers.

The Echo SE is a portable USB drive that can perform automatic backup and transfer of files, at read speeds up to 28MB/s and write speeds up to 10MB/s, while the Echo ZE is a desktop drive with a 20.1 by 15.1mm profile.

The drives include built-in Echo backup software developed by Dmailer for Lexar. Key features include targeted file backup, which stores only specified files and reduces wasted disk space, and file versioning, which backs up a history of files and allows the retrieval of previous versions. Additionally, the software offers optional AES 128-bit encryption, enabling protection in the event of drive loss.
