Mercury Systems’ first prototypes of its 3U TRRUST-Stor VPX RT space-qualified secure solid-state drives (SSD) are designed to operate reliably in high-radiation environments. The devices are said to be the first commercial SSD leveraging VITA 78 SpaceVPX standards to reduce customer cost and mitigate program risk. In addition to commercial satellite applications, this device is ideally suited for high-altitude aircraft, airborne weapons, and mission-critical ground computing systems.
Driving the SSD is Mercury’s proprietary NAND controller with BuiltSECURE error correcting code (ECC) algorithms. These ECC algorithms mitigate radiation-induced byte errors, thereby enabling sustainable reliability and fault tolerance that are not available with competing storage solutions. As Mercury maintains 100% authority over the controller and its implementation, this device is readily customizable for non-traditional use cases when deemed critical to a user’s program.
The TRRUST-Stor VPX RT device is engineered into an open standards platform, allowing users to seamlessly integrate it into the SpaceVPX ecosystem of processing boards and chassis without sacrificing affordability. As the need for radiation-tolerant devices for LEO satellites proliferates, system development around the SpaceVPX open standard architecture will be integral in supporting the growth of the space market.
