Exascend Zhiyu Technology Launches AS500 Series Solid-State Drive for Autonomous Vehicles

TapTechNews May 18th news, Exascend Zhiyu Technology launched the AS500 series single-chip PCIe 4.0 BGA solid-state drive product, which can work normally in the range of -40°F to +221°F and is specifically designed for the next-generation autonomous vehicles.

The Zhiyu AS500 BGA solid-state drive supports the PCIe 4.0 protocol, adopts a 291 Ball BGA package with a size of 0.63 inches x 0.79 inches, uses 3D TLC flash memory, and has optional capacities of 128GB/256GB/512GB/1TB.

This hard drive has no built-in DRAM cache and adopts the HMB (Host Memory Buffer) scheme. The performance parameters are as follows:

128GB: The maximum continuous read speed is 1800 MB/s, the maximum continuous write speed is 200 MB/s, and 75 TBW.

256GB: The maximum continuous read speed is 3500 MB/s, the maximum continuous write speed is 400 MB/s, and 150 TBW.

512GB: The maximum continuous read speed is 5000 MB/s, the maximum continuous write speed is 800 MB/s, and 300 TBW.

1TB: The maximum continuous read speed is 5000 MB/s, the maximum continuous write speed is 1600 MB/s, and 600 TBW.

TapTechNews summarizes the characteristics of AS500 as follows:

Built-in SR-IOV function enables virtual machines to share a single physical PCIe device.

Power consumption is less than 3.5 watts, and standby power consumption is less than 1 watt.

AEC-Q100 Grade 2 testing is in progress.

Optional TCG Opal 2.0 support.
