PE4 Series Achieves Two-Fold Storage Density While Consuming 50% Less Power
TAIPEI, July 15, 2025 /PRNewswire/ — Exascend, a global leader in advanced storage and memory solutions, today expanded its power-efficient PE4 enterprise SSD line with two new 7 mm U.2 models: 23.04TB and 30.72TB. Delivering up to 4.5TB of storage per millimeter of thickness, these drives delivers best-in-class capacity currently available in a 7 mm form factor while cutting typical power consumption in half. The new PE4 models enable system integrators to maximize capacity in edge servers, rugged industrial computers, on-premises AI nodes, and space-constrained data centers where every watt and every millimeter count.
Exascend Unveils Industry-First 30.72TB 7mm U.2 SSD for Edge Storage
Unrivaled Density and Power Efficiency
The PE4 30.72TB doubles the density of competing 7mm U.2 SSD and enables up to 737TB of flash in a single 1U server, cutting rack space requirements by 50 percent compared to 15mm drives and delivers a two-fold jump in TB-per-U efficiency.
With active power draw of just 7 watts and under 1.5 watts at idle—a 70% reduction versus typical alternatives—these drives excel at applications where power budget is limited. This efficiency helps lower energy costs and supports sustainable operations by minimizing cooling requirements.
For edge storage deployments, the PE4 series addresses challenges in remote or infrastructure-limited settings, including space and power limited systems, by combining compact form factors with power efficiency. This allows for greater data capacity without increasing power demands or physical footprint, facilitating applications like real-time analytics at the network edge.
“The PE4 30.72TB isn’t just an incremental step forward. It’s a paradigm shift for edge and on-premises storage” said Frank Chen, CEO at Exascend. “By delivering 30.72TB of storage in a 7mm slim form factor while cutting power consumption by 50%, we enable customers to scale storage density without overhauling existing thermal design or server layout. For customers that needs a sweet spot between 15.36TB and 30.72TB, our new 23.04TB model delivers extra storage headroom at a more budget friendly price point.“
Engineered for Thermal-Challenged Environments
High-capacity enterprise SSDs suffer performance degradation in tight spaces with poor airflow. The PE4 23.04TB and 30.72TB models overcomes this challenge with Exascend’s exclusive Adaptive Thermal Control™ technology, maintaining consistent throughput in ambient temperatures up to 70°C without suffering performance hindering thermal throttling.
Its performance stability is protected by intelligent thermal engineering, integrating low power hardware design, optimized controller placement, thermal mitigation, and a casing design that enhances heat dissipation. The ATC predictive algorithm continuously monitors and tunes power and performance to prevent thermal buildup, making the new PE4 models ideal for edge servers, rugged industrial systems, high-density storage arrays, and AI workloads operating in thermally constrained environments.
Enterprise-Class Performance, Reliability, and Security
Featuring a PCIe Gen4 x4 interface and engineered with 3D TLC NAND, the PE4 series is rated for up to 1 drive write per day (DWPD) and offers a 2-million-hour mean time between failures (MTBF), ensuring reliability in always-on environments.
The drive also includes security features such as AES-256 hardware encryption, TCG OPAL 2.0 compliance, and end-to-end data protection using advanced LDPC and RAID-level parity. Built-in hardware power-loss protection, support for NVMe namespaces, and field-upgradeable firmware make it ideal for enterprise and multi-tenant deployments.
Customization services are available to meet specific OEM and integrator requirements.
Availability
Engineering samples of the PE4 Series U.2 SSD in 23.04TB and 30.72TB models are shipping now to select customers, with volume production scheduled for Q3 2025. The PE4 7mm family are already available in 7.68TB and 15.36TB capacities.
