Mercury RH3480 SSD Recorder

The RH3480 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, serving industry needs for reliable, SWaP-optimized storage solutions as edge applications advance. Plus, the RH3480 offers long-term data integrity with the most powerful error correction code (ECC) available.
