The first DRAM-less SSD controller to max out PCIe Gen5. It is also a power efficiency champion in the making
Phison’s E37T controller is shaping up to be a powerful, yet efficient option in a market desperate for affordability.

As rising SSD prices force budget-conscious consumers toward affordable storage, the upcoming Phison E37T DRAM-less SSD controller offers a high-performance, cost-effective solution.
Key highlights:
- Pushes PCIe 5.0 Limits: It is the first DRAM-less controller to max out bandwidth across four M.2 lanes, reaching read speeds of 14.9 GB/s and write speeds of 13 GB/s.
- High Efficiency: Consumes a low peak power of 3.4W, offering enthusiast-grade performance with significant energy savings.
- Performance Boost: Provides a sub-50% increase in IOPS over the older E31T, rivaling the performance of high-end DRAM-equipped controllers like the E26 at a lower price point.
