Industrial flash architecture shifts to pSLC to protect long-term sourcing margins
Exascend has expanded its embedded storage portfolio with the introduction of hardware-based power loss protection and pSLC configurations across its latest enterprise and industrial PCIe Gen 5 SSDs.
The architecture addresses immediate industrial demand for components capable of enduring extreme temperature fluctuations while securing predictable manufacturing lead times amid global wafer reallocations.
According to a market survey from TrendForce, NAND flash contract prices are projected to rise 10% to 15% quarter-over-quarter in Q3 2026, forcing a commercial transition toward high-end component sourcing that prioritises long-term drive endurance over raw capacity.
Technical Specifications Across the Product Portfolio
The new catalogue expands the portfolio spanning DRAM, enterprise and industrial solid-state drives, managed NAND, and removable memory cards. Within the DRAM segment, standard-temperature DDR4 modules operate at 3200 MT/s with capacities up to 32GB at 1.2V. For newer architectures, the Exascend supplies standard and industrial-temperature DDR5 modules reaching data rates of 5600 MT/s across U-DIMM and SO-DIMM form factors, featuring operational tolerance from -40°C to 95°C. Low-power environments are supported by 315-ball BGA LPDDR5 ICs, delivering 6400 MT/s at capacities of 32Gb and 64Gb.
Solid-state storage tiers are divided by performance generation and workload profile. The PCIe Gen 4 PE4 Streaming series provides capacities up to 30.72TB in the U.2 form factor, maintaining sequential read speeds up to 3,350 MB/s. For high-write enterprise setups, the pSLC-based PE4 Max series guarantees an endurance rating of 25 drive writes per day (DWPD) over a five-year period. Emerging PCIe Gen 5 architectures, including the upcoming PE5 and PD5 series, scale capacities up to 30.72TB with random read performance rated up to 3.4 million IOPS.
Component Sourcing and Supply Chain Metrics
Manufacturing planning requires strict compliance with international reliability metrics. The catalogue introduces space-grade and automotive hardware designed to eliminate component failure risks. The radiation-tolerant PR4 Series (v2) NVMe M.2 SSD features third-party certifications including ESCC 22900 Total Ionising Dose (TID) at 25Krad and ESCC 25100 Single-Event Effects (SEE) at 37.5 MeV.
Managed NAND solutions focus on eMMC 5.1 architectures under the EM500 and EM300 series, which incorporate AEC-Q100 Grade 2 certification for automotive integration, sustaining operating temperatures between -40°C and 105°C. Removable memory options encompass industrial-grade microSD, SD, CFast, and CFexpress Type B cards. The CFB400 CFexpress line uses PCIe 3.0 x2 connectivity to deliver up to 3,500 MB/s sequential read performance, whereas the CFB300 series implements PCIe 4.0 x2 interfaces.
According to the official product brief, the hardware strategy centres on “strategic relationships with suppliers” to ensure product lifecycle support. The manufacturer states that the architecture delivers “performance, reliability, and durability across full-spectrum of applications”.
Legacy SATA and Wide-Temperature Alternatives
For systems requiring backwards compatibility, the legacy enterprise SATA portfolio includes the SE4 Streaming and Pro/Max series. These 6.0Gb/s drives deliver up to 15.36TB of storage with active power consumption constrained below 2.8W. The wide-temperature industrial equivalents, such as the SV4 and SI4 series, expand thermal tolerance to a range of -40°C to 85°C, ensuring component stability in harsh deployment environments.
Damian Semple, Franchise Marketing Manager, comments: “Component selection must look beyond initial acquisition costs to account for the volatile pricing projections defining the current NAND flash market. Choosing highly durable pSLC configurations or drives with integrated power loss protection mitigates long-term field replacement risks and secures component lifecycle stability. Sourcing certified automotive and space-grade memory provides the component traceability required to safeguard production timelines against sudden market constraints.”
