Phison E37T PCIe Gen5 Controller: Power-Efficient Storage for Emerging Device Demands
Phison Electronics unveils its E37T PCIe Gen5 controller at CES 2026, targeting the growing need for high-performance storage in compact consumer devices. This DRAM-less solution promises a 38% performance uplift over prior generations while maintaining low power draw. For C-suite leaders in hardware and OEM sectors, it signals a shift toward cost-effective scalability in notebooks and handhelds.
The announcement underscores Phison’s strategy to balance speed, efficiency, and affordability amid PCIe Gen5 adoption. As platforms shrink, executives must evaluate controllers that sustain performance without inflating costs or thermals.
E37T Architecture: Refinements for Mainstream Adoption
Phison’s E37T builds on 3D NAND advancements, supporting speeds up to 4800 MT/s across four channels. Its single-sided M.2 form factors—2280, 2242, and 2230—fit slim notebooks and mobile gaming devices seamlessly.
Key refinements include a DRAM-less design that cuts power to under 2.3W during active use. This yields sequential reads up to 14.7 GB/s and writes to 13.0 GB/s, alongside 2,000K 4KB random IOPS.
- Power Efficiency: Active consumption below 2.3W enables prolonged battery life in portables.
- Form Factor Flexibility: Supports compact SSDs without performance trade-offs.
- NAND Compatibility: Optimized for latest 3D TLC, enhancing price-to-performance ratios.
- Thermal Management: Lower heat output suits fanless or densely packed systems.
These specs position the E37T for OEMs seeking Gen5 benefits at Gen4 prices. Phison’s official E37T page offers detailed datasheets for procurement teams.
Michael Wu, Phison US President and GM, notes the controller addresses spatial constraints in next-wave platforms. It delivers responsive experiences across diverse workloads, from everyday computing to light creative tasks.
Comparing E37T to Phison’s Flagship E28: Tiered Performance Strategies
Phison’s E28 PCIe Gen5 controller contrasts with the E37T by prioritizing raw speed for premium segments. Fabricated on TSMC’s 6nm process, the E28 hits 14.9 GB/s reads and 14 GB/s writes, now scalable to 8TB capacities.
The E28’s eight-channel, DRAM-cached setup excels in gaming rigs and workstations, where NVMe 2.0 protocols minimize latency. It sets benchmarks for sustained throughput under heavy loads like 4K video editing or simulations.
| Feature | E37T (Mainstream) | E28 (Flagship) |
|---|---|---|
| Channels | 4 | 8 |
| DRAM | None | Yes |
| Seq. Read/Write | 14.7/13.0 GB/s | 14.9/14.0 GB/s |
| Power (Active) | <2.3W | Higher (optimized efficiency) |
| Target Use | Notebooks, handhelds | Gaming, workstations |
| Form Factors | 2280/2242/2230 | Larger capacities up to 8TB |
This tiering allows Phison to capture both volume-driven consumer markets and high-margin pro segments. Executives can mix E37T for cost-sensitive SKUs and E28 for differentiated flagships, optimizing portfolios.
Transitioning to enterprise, Phison extends Gen5 prowess beyond clients. The CES showcase highlights how these controllers inform broader supply chain decisions.
Pascari Enterprise SSDs: From Extreme Performance to Hyperscale Efficiency
Phison’s Pascari lineup addresses data center imperatives with the X201 and D201 SSDs. The X201 tackles AI training, high-frequency trading, and HPC, delivering ultra-low latency and high throughput on PCIe Gen5 rails.
Built for read-intensive extremes, the X201 pairs robust endurance with power-efficient reliability. It supports workloads demanding sub-millisecond responses, critical for real-time analytics.
Meanwhile, the D201 optimizes for hyperscale clouds, object storage, and database clusters. Its design emphasizes density and consolidation, reducing TCO in expansive environments.
- X201 Strengths: Exceptional IOPS for AI/HPC; low-latency edge in trading platforms.
- D201 Advantages: High-capacity efficiency for CDN and data lakes; enterprise-grade durability.
- Shared Gen5 Backbone: Both leverage NVMe 2.0 for scalable throughput.
- Power Optimization: Balances speed with operational costs in 24/7 deployments.
