BOULDER, Colo. (Jan. 15, 2007) — ProStor Systems, the leading developer of removable disk storage solutions, today announced the addition of a 160 GB capacity to its lineup of RDX^® removable disk cartridges — a 33% increase over its previous capacity. RDX media is now available with native cartridge capacities of 40, 80, 120 and 160 GB, allowing small and medium-sized business users a choice of cartridge capacities and backup options for their servers and workstations. Like all RDX cartridges, the new 160 GB capacity is fully forward and backward compatible with all RDX drives.

RDX technology is the new multi-vendor standard in removable disk storage media for backup, archive and portable data applications. Compatible RDX solutions are available from several companies, including Tandberg Data, Imation and a leading PC and server manufacturer.

"We recognize the importance of professional-grade data protection for small and medium-sized businesses, said Steve Georgis, CEO and president of ProStor Systems. "That’s why we remain committed to advancing RDX technology to its greatest potential, providing the most reliable and best price / performance / capacity ratio of any removable media solution for the SMB user," he added. "Small businesses are replacing low-end tape and fixed disk storage with RDX technology because it’s fast, safe, transportable and easy to use."

Designed with enterprise-class features, RDX cartridges and drives back up more than 125 GB of data per hour, access files instantly and archive data safely for more than a decade. The RDX storage solution is 10 times faster and more reliable than any tape storage product used in the past by small and midsized

Commenting on the announcement, James Ellis, vice president of strategic growth programs at Imation, said, "We are pleased to support RDX technology, a forward- and backward-compatible technology. Users need not purchase a new drive to take advantage of improved capacity as new cartridges will continue to work in existing drives. With a choice of capacities to meet individual needs from 40 GB to 160 GB, we see RDX technology providing an extremely attractive set of storage attributes to the SMB user."
