PHISON – E28 Controller Could Make It The New King of PCIe 5.0 Performance

“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.

. . .

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
