Featured Storage Technologies


Optimized Write Performance

Exascend's unique SuperCruise™ algorithm optimizes the ratio of free block availability and usage, prioritizing and regulating response time to ensure a consistently high level of performance.


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.


Dual Power Loss Protection (PLP)

Through a combination of hardware and firmware-based PLP, we institute a robust safeguard against data integrity complications during abrupt power outages. This dual protection mechanism ensures that all data in transit is securely stored before any shutdown occurs.


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.


Data Integrity and Retention

Exascend employs advanced firmware technologies such as RAID ECC and Data Path Protection to mitigate the likelihood of data errors and facilitate error detection and correction during data transmission. Additionally, our Data Retention Plus™ technology refreshes stored data based on usage patterns, ensuring data reliability.


Tailored Over-Provisioning Capabilities

Exascend's Unlimited Over-Provisioning technology allows users to set the optimal level of over-provisioning for their applications, customizing it to suit specific workloads and operational requirements.
