Mercury Systems one of the leading technology companies serving the global aerospace and defense industry has showcased a new high-density Radiation Tolerant Solid-State Data Recorder for satellites and launch vehicles.
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.
The SSDR features a 440 GB large geometry, industrial-grade SLC NAND flash memory, and a proprietary horizontal Reed-Solomon algorithm for error correction. All components used are radiation tolerant by design (except NAND) at greater than 100 krad. The NAND is screened to NASA EEE-INST-002. The SSDR is VPX compatible, VITA 48.2 compliant, and P2 unpopulated.
Performance
- SRIO interface running at 3.125 Gbit/s
- 4-lane writes 1160 MB/s, reads 1040 MB/s
- 1-lane writes 250 MB/s, reads 225 MB/s
The RH3440 comes in a 3U form factor and measures 160 x 100 mm in size with a 1-inch pitch. It weighs less than 620 grams and is microprocessor and software free. The SSDR is suitable for applications such as LEO satellites, launch vehicles, scientific missions, and mission-critical ground computing subsystems.
