ProStor Systems, a provider of removable disk storage systems for business backup, archiving and retention management, has released the new ProStor InfiniVault Model 5 for small-to-medium sized providers that may have two different data retention requirements, and where two copies of the data are necessary for disaster protection.

According to the Boulder, Colo.-based company, the ProStor InfiniVault Model 5 is a storage appliance in a tower design with five slots for RDX removable disks and a 1.8TB file area that can manage 250 million files. Using 500GB RDX removable disk cartridges, ProStor InfiniVault Model 5 is able to keep 2.5TB (5TB compressed) data online (in RDX removable disk cartridges) and an infinite amount of data capacity offline. In an application requiring two separate retention periods, the Model 5 can be configured to provide self protection while allowing RDX removable disks to be sent offsite for disaster protection.
