The XSR Removable Data Module (RDM) fits all Galleon data recorders, NAS, and servers, providing an extremely flexible data solution to suit the target application. The RDM can be exchanged in the field in seconds, with no tools required.


The data module uses industry-standard 2.5” solid-state storage (SSD) modules. Up to four different SSDs can be fitted supporting capacities up to 80TB total. All varieties of SSDs can be used, ranging from military-grade ultra-rugged to commercial-grade for lab and development systems.


Consequently, the storage can be optimized depending on the usage and specific needs. For example, commercial grade storage can be used for lab development and pre-deployment usage, where cost and optimization are of higher importance than data integrity. Then, when the unit is used on critical missions, industrial-grade storage can be used to meet the most demanding environments.


For additional security, optional AES 256-bit encryption may be added either internally to the RDM or part of the XSR unit. Further security enhancements such as quick erase and secure erase are supported on selected storage media.


Galleon Embedded Computing’s quality management system is certified to Aerospace Standard AS/EN 9100 and ISO 9001.
