Dragonfly's SSMM is a flight-proven, high-reliability, high-speed solid-state mass memory designed for low Earth orbit spacecraft. It features a Eurocard 3U form factor, a storage capacity of 512 GB, and read/write speeds of up to 26 Gbps. The SSMM can operate independently or be combined with multiple units to form larger memory banks.
The SSMM includes built-in ECC and bad block management to ensure data integrity, as well as JPEG 2000 lossless compression to save space and reduce download times.
