Overview

Industry‘s 1st COTS-based Flash Storage Purpose Designed for Radiation-Intense Low Earth Orbit Environments

Radiation-Hardened by Design (RHBD) Resilience

The PR4 SSD combines ultra-reliable commercial off-the-shelf (COTS) components with groundbreaking PhoenixCore technology. This self-healing, regenerative firmware architecture rapidly cleanse errors caused by radiation, ensuring robust resilience and continuous system operation.

Radiation-Hardened by Process (RHBP) Resilience

Radiation hardening by process, implements custom manufacturing process adding addtional layer of radiation tolerant material to protect against sprectrum of alpha, beta, gamma, neutron and heavy ion radiation.

Low Power Design for Power Budget Constrained Space Applications

Leveraging Exascend’s proprietary technologies, the PR4 Series SSD achieves outstanding energy efficiency, with average power consumption of less than 8.5W during peak performance, making it an excellent choice for space applications with limited power budgets.
