480 GB 3U VPX Rad-Tolerant SSDR

On-orbit data storage, commercially available

Preserve up to 480 GB of data in radioactive environments

The RH3480 solid-state data recorder (SSDR) is purpose-built to withstand harsh, radiation-intense environments, such as those found in LEO satellites and in certain industrial or medical settings. Designed in a compact 3U form factor, the RH3480 is the highest density SSDR available on the market, satisfying industry needs for reliable, SWaP-optimized storage solutions for advanced edge applications. Plus, the RH3480 offers long-term data integrity with the most powerful error correction code (ECC) available.
