Purpose-Built for Connected and Autonomous Vehicles

Optimized Thermal Management

Exascend's proprietary algorithm, Adaptive Thermal Control™, ensures sustained peak performance while effectively regulating the drive's temperature within specified thresholds. By combining adaptive hardware power reduction and intelligent SSD performance management, our automotive-grade SSDs maintain optimal functionality even in challenging thermal environments.

DRAM-Less with Host Memory Buffer (HMB) Support

Benefit from Host Memory Buffer (HMB) support in our DRAM-less SSDs, enhancing performance by utilizing DRAM resources as cache. This innovative approach mitigates the storage's limited memory capacity, optimizing I/O performance without necessitating onboard DRAM.

Optimized Power Consumption

With an exceptionally low power consumption of just less than 3.5W in active mode, the AS500 SSDs deliver significant power savings without compromising performance.

Built-in Single Root-IO Virtualization (SR-IOV*)

The AS500 features built-in SR-IOV capabilities, enabling up to four direct, high-speed PCIe interfaces for virtualized environments. Each virtual machine (VM) connects via a dedicated virtual function (VF) in the SSD controller, eliminating hypervisor overhead for near-native performance. This innovative architecture delivers cost savings by consolidating multiple storage devices, low latency with flexible QoS, and reduced CPU utilization.

* SR-IOV will be enabled through future firmware updates upon successful validation and implementation.

Reliable Wide-Temp BGA SSD with Rigorous QC Testing

Exascend AS500 BGA SSD undergoes a rigorous QC testing regimen during production, featuring an extensive wide-temperature burn-in test spanning from -40°C to 105°C. This testing surpasses commercial grade standards and guarantees that our wide temperature products will consistently operate reliably and perform optimally in extreme and rapidly fluctuating temperatures.
