Phison is demonstrating the capabilities of its upcoming flagship E28 PCIe 5.0 controller at Computex 2025, 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 CES 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 and 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.
