Featured Storage Technologies
Wide Temperature
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.
Optimized Thermal and Write Performance
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.
Enhanced Power Efficiency
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.
Data Security and Encryption
TCG Opal 2.0-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.
Uncompromised Data Integrity
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.
