PHISON – First SSD Controller With Built-In AI Processing

By | May 23, 2025 | Phison in the News

“Phison has launched the E28 PCIe 5.0 SSD controller, the first with integrated AI processing, built on TSMC’s 6nm process. This development in AI-enabled storage technology supports AI model updates and improves system performance via integrated processing. It delivers up to 2,600K/3,000K IOPS (random read/write), exceeding other solutions by over 10%, while using up to 15% less power than the other six nm-based controllers. The E28 balances bandwidth and power, achieving a 15–30% higher performance-to-power ratio than competing products.

Explicitly designed for AI workloads, the E28 includes built-in circuitry to accelerate data flow during inference and token processing. Phison states that this AI acceleration can reduce training times by up to 50%. The controller targets AI workstations and servers where performance is prioritised over cost, and is not intended for general consumers or PC gaming.

Gaming SSDs have improved sequential read/write speeds but remain slow in random operations, which affects system responsiveness and the perceived speed of PCs. Sequential speeds mainly impact tasks like loading games or levels. The E28 offers random performance up to 240% faster than current gaming SSDs, suggesting future mainstream drives could feel more responsive.

Some of the key features of the E28 include:

  • First PCIe 5.0 SSD controller with built-in AI
  • Made with TSMC 6nm process
  • Faster random read/write (2.6M/3M IOPS)
  • Uses 15% less power
  • Better performance-to-power ratio
  • Speeds up AI tasks, cuts training time by 50%
  • Made for AI servers, not gaming PCs
  • Random speed 240% faster than gaming SSDs

While the E28 focuses on the AI market, future versions and related models are expected to enhance random performance for everyday PCs and gaming systems.”- electronicsforu.com
