Mercury RH3440 SSD Recorder

The RH3440 is the world’s first commercially available, high-density SSDR in a compact 3U form factor. Precision-engineered and purpose built to withstand harsh, radiation intense environments on earth and beyond, the RH3440 serves industry needs for reliable, SWaP-optimized storage solutions. Plus, the RH3440 offers long-term data integrity with Mercury proprietary defect mitigation and the most powerful error correction code (ECC) available.
