Lexar Media, a provider of memory products for digital media, has launched flash-based, backup drives Echo SE and Echo ZE. The drives provide users with portable, file backup services for netbook and notebook computers.

According to Lexar Media, the Echo SE is an ultra-portable drive that plugs into a computer’s USB port to perform automatic backup and transfer of files, at read speeds up to 28MB/s and write speeds up to 10MB/s. Echo ZE, with its 20.1 by 15.1 millimeter size and plug-and-stay design, is a drive providing a means to automatically back up essential files. Both drives are interoperable between Windows XP, Windows Vista, and Windows 7, as well as Mac OS X operating systems.

The drives include built-in Echo backup software developed by Dmailer for Lexar. Features include, targeted file backup that 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.

In addition, the software offers optional AES 128-bit encryption, enabling protection in the event of drive loss. The Echo SE backup drive is available in capacities of 16GB, 32GB and 64GB, and the Echo ZE backup drive is available in capacities of 8GB, 16GB and 32GB.

Aaron Lee, senior product marketing manager at Lexar Media, said: More than one out of three participants in the recent Parks Associates survey, ‘Mobile Convergence,’ expressed interest in a flash-based drive with automatic backup software for their netbook or notebook, and Echo SE and ZE answer that demand. Unlike traditional backup solutions which require external hard drives and cables, the Echo line is designed for users on the go.
