Exascend Inc. announces a line of PCIe 4.0 NVMe SSDs: the PI4 series.
Featuring PCIe 4.0 technology, capacity, and energy efficiency, the series brings low-power enterprise storage into next-gen industrial applications. Available in the M.2, U.2 and E1.S form factors, the lineup establishes Exascend as the first flash storage provider to support industrial PCIe Gen4 E1.S storage.
Enterprise PCIe Gen4 performance ready for integration
PI4 series utilizes the PCIe 4.0 interface with NAND flash support from Micron and Kioxia for forward and backward compatibility – making it a future-proof upgrade. It leverages the company‘s trademark hardware and firmware technologies to deliver reliable enterprise performance – providing high QoS to maximize the performance of latency-sensitive systems. This means that system integrators and industrial innovators can bring staggering enterprise PCIe Gen4 performance to ttough applications.
Higher transfer speeds at lower power draw
The PI4 series is paired with Marvell Technology, Inc.‘s 12nm controller and the latest industrial-grade 3D TLC NAND flash for performance and low power consumption, delivering sustained transfer speeds of up to 3,500MB/s and 4K random speeds of up to 600,000 IO/s. In addition, it offers energy savings when compared to its predecessors, improving write performance per watt by a 143% – marking the company‘s most recent effort to reduce customers’ carbon footprint through low power PCIe storage.
Engineered to withstand harsh industrial conditions on the edge
The PI4 series is designed to address performance-hampering factors commonly found in edge applications, including small space, overheating, extreme temperatures, mechanical stress and unstable power supply. The SSDs can operate in temperatures from -40°F to +185°F (-40°C to +85°C). They are certified to withstand mechanical stress and vibrations, featuring the company‘s proprietary Adaptive Thermal Control (ATC) firmware technology for stable top-level performance without thermal-throttling-induced drops and spikes.
With its high sustained performance under heavy data loads, the series is for write-intensive applications such as rugged edge servers, autonomous driving systems, surveillance, and big data logging systems. It has entered validation with customers in the autonomous driving and data logging sectors now testing product samples.
Unparalleled customization services and design expertise
PI4 SSDs feature technologies, including firmware and hardware-level power loss protection (Dual Power Loss Protection), hardware RAID ECC, Data Retention Plus, and Neutron Shield – all developed to ensure data integrity and security. The SSDs incorporate firm‘s proprietary SuperCruise technology for low latency and stable write performance, which translates into high QoS.
Moreover, the company’s integrated product development and firmware design expertise allows the firm to provide levels of product customization – resulting in tailored solutions for any application. Optional advanced features include TCG Opal 2.0, AES-256 encryption, Unlimited Over-Provisioning, Custom Data Sanitization, Data Path Protection.
Configurations and availability
Product samples for the PI4 series are available for customers upon request. The series is available in both standard and pSLC configurations with storage capacities from 960GB to 7,680GB and endurance ratings up to 24,000TBW, based on JESD219 Enterprise Workload.
The PI4 series comes in M.2 2280 and U.2 form factors for broad system compatibility; a DRAM-less M.2 2230 option for compact systems; and a rugged E1.S design – combining performance, capacity and hardware power loss protection in a thermally-efficient next-gen design. Catering to different thermal environments, E1.S SSDs can be configured with heat spreaders, asymmetric and symmetric enclosures.
All models are covered by 3-year limited warranty.
