Phison’s SSD controllers already power many of the world’s best SSDs, and the company is set to extend its industry dominance. The new PS5037-E37T PCIe 5.0 SSD controller delivers blazing speed and remarkable power efficiency—engineered specifically for compact devices like laptops and gaming handhelds.
While Phison’s class-leading PS5028-E28 controller set the benchmark for raw performance, the new E37T takes a different approach by prioritizing exceptional power efficiency and affordability—without sacrificing impressive speeds. Manufactured by TSMC using an advanced 6nm process node, the E37T features a cutting-edge DRAM-less architecture and supports four NAND channels with transfer rates up to 4,800 MT/s. This innovative design enables the E37T to deliver a remarkable 38% performance boost over previous-generation PCIe 5.0 DRAM-less controllers, such as the PS5031-E31T.
The E37T delivers impressive sequential read speeds of up to 14.7 GB/s and sequential write speeds of up to 13 GB/s with an active power below 2.3W. According to Phison, the drive’s random performance is rated at up to 2,000,000 IOPS for both reads and writes. Compared to the flagship E28 controller, the E37T holds its ground in sequential performance: read speeds are only marginally slower, and write speeds are just about 7% lower.
At CES 2026, Phison delivered a show-stopping demonstration of the E37T prototype in action—surpassing even the company’s own lofty performance claims. The drive achieved blistering sequential read speeds of 14,926.78 MB/s and write speeds of 13,180.21 MB/s, all while maintaining an impressively low power draw of just 2.13W. For added real-world validation, a live CrystalDiskMark benchmark revealed the E37T-powered drive peaking at 4.47W under heavy load.
SSDs powered by the E37T controller will hit the market soon, ushering in a new wave of high-performance, energy-efficient storage options for compact devices. Engineered for versatility, the E37T will be featured in various drive form factors—such as M.2 2280, M.2 2242, and the ultra-compact M.2 2230—making it an ideal solution for everything from slim laptops to portable gaming consoles.
Phison E28 Roars Ahead: Next-Level Performance Gets Epic Capacity Upgrade
While the E37T grabbed headlines at CES 2026, Phison made waves with a major update on its flagship E28 controller. The company announced that next-generation E28-powered 8TB SSDs are right around the corner. With only a handful of consumer PCIe 5.0 8TB SSDs currently available—such as the WD Black SN8100, or should we say the Optimus GX Pro 8100, and Samsung 9100 Pro—Phison is set to seize a wide-open market with its E28-based drives. This move not only reaffirms Phison’s leadership in storage innovation but also promises to redefine what’s possible for high-capacity, high-performance SSDs.
We witnessed the E28 8TB SSD prototype in action—and it lived up to every bit of the hype. The drive shattered expectations, delivering blistering sequential read speeds of 14,919.18 MB/s and write speeds of 14,088.25 MB/s, soaring far beyond Phison’s own official numbers for the controller.
The biggest hurdle facing E28 8TB drives is the global NAND shortage and the insatiable demand created by the AI boom—a factor that’s already driven SSD and memory prices sky-high. As a result, these cutting-edge PCIe 5.0 8TB drives will likely come with a hefty price tag. For now, the E28 8TB SSDs could remain out of reach for most consumers. However, there is hope on the horizon: as the market eventually cools and the AI-driven frenzy subsides, SSD prices will begin to stabilize. When that happens, high-capacity drives like the E28-based 8TB ones will become more accessible, opening up exciting new storage possibilities without the premium price tag.
