Engineered for extreme environments, the SA4 series boasts ISO16750-3 certification for automotive vibration and MIL-STD-810 compliance. With added protection from conformal coating and underfill technologies, it provides superior defense against humidity, shock, and vibration.
With Exascend's proprietary technologies, the SA4 achieves maximum performance while drawing less than 7W of power, providing enhanced energy efficiency.
By collaborating with top-tier NAND flash manufacturers and SSD controller creators, we have engineered a bespoke firmware architecture that seamlessly unites advanced hardware and innovative design. This empowers flash storage, providing tailored solutions for success.
Built to the highest standards, our products boast MIL-STD-810 compliance, conformal coating, and underfill technologies, providing unparalleled protection against humidity, shock, vibration, and environmental factors.
Exascend’s wide temperature technology leverages a unique combination of high-quality components, purpose-designed hardware and highly-optimized firmware to deliver unmatched wide temperature performance and stability.
Our Adaptive Thermal Control™ technology enhances system thermals, airflow, and acoustics, reducing BOM costs. The SuperCruise™ algorithm optimizes write performance, boosting long-term stability and overall reliability.
TCG Opal 2.01-compliant, our self-encrypting drives (SEDs) support AES-256 encryption, BitLocker, and IEEE 1667. Customize with pre-boot authentication (PBA), data sanitization, and Tamper-Proof Firmware for enhanced security.
Leveraging RAID5 at a flash memory block level, our unique RAID ECC recovers severely corrupted data. In sudden power loss, our hardware and firmware power loss protection (PLP) ensures data integrity.
Our control in hardware, firmware and manufacturing allows unmatched power tuning services. Tailoring product performance for your applications achieves optimal performance-to-thermal and performance-to-power ratios.
