“Phison is demonstrating the capabilities of its upcoming flagship E28 PCIe 5.0 controller at 2025年台北國際電腦展, where it appears to excel over its rivals. The E28 thrashes competitors like Samsung’s fastest 9100 Pro offerings in random reads and writes, achieving parity in sequential reads and delivering impressive efficiency numbers.

Building on its 國際消費電子展 2025 unveiling, the E28 is now roaring to life, driving a reference platform. The Phison E28 serves as the company’s long-awaited successor to the E26, which for a long while was hailed as the fastest PCIe 5.0 offering, eventually surpassed by SiliconMotion’s SM2508 和 Samsung’s Presto. The E28 is fabbed using TSCM’s 6nm process, compared to the 12 nm-based E26, while supporting upwards of 32TB of TLC flash along with robust error correction technologies like LPDC and RAID ECC. It supports an eight-channel layout at 4200 MT/s along with AES-256, TCG Opal, and Pyrite encryption capabilities.

Phison advertises the E28 with 14.8 GB/s and 14 GB/s sequential read and write speeds, only second to SanDisk’s WD SN8100. The E28 truly excels in random I/O, thrashing all competition with remarkable read and write IOPS of 2,600K and 3,000K, respectively. This effectively dethrones Samsung’s Presto-powered 9100 Pro by 400 IOPS across each department. The E28 is touted by Phison as the first controller to feature integrated AI processing, which supposedly makes future SSDs powered by these controllers a great fit for accelerating AI/ML workloads and the like.”- tomshardware.com
