PHISON – Showcases New E28 SSD controller

The original E26 controller was powerful, but it traded off higher power consumption for extreme performance, thus resulting in higher heat generation that not only required robust cooling solutions but also hampered its use in laptops.

The Phison E28 delivers huge efficiency gains by using a smaller 6nm process node that cuts power consumption dramatically. At Computex 2025, Phison demoed its new controller handily beating the competing SMI 2508 in power consumption during nearly every type of operation. That equates to lower heat generation, meaning these SSDs won’t require bulky coolers, and will also help PCIe 5.0 SSDs finally make their way into mainstream OEM laptops.

Phison didn’t skimp on performance to reduce the power consumption, though. The Phison E28 delivers up to 14.8 GB/s of sequential read/write performance and a blistering 2.5 / 3.0 million random read/write IOPS, speeds which were unthinkable a mere few years ago.

Phison says we’ll see a wave of E28-powered SSDs coming later this year, with a likely CES 2026 launch date. In fact, we saw plenty of E28 SSDs scattered throughout the Computex show floor at all of the main SSD vendors, proving that we won’t have to wait much longer for SSDs with extreme speeds coupled with excellent power efficiency.”- tomshardware.com
