At Computex 2023, Phison is introducing a new, lower-cost SSD controller for building mainstream PCIe 5.0 SSDs. The Phison PS5031-E31T is a quad channel, DRAM-less controller for solid-state drives that is designed to offer sequential read/write speeds up to 10,8 GB/s at drive capacities of up to 8 TB, which is in line with some of the fastest PCIe 5.0 SSDs available today. The Phison E31T controller is, at a high level, the lower-cost counterpart to Phison's current high-end PCIe 5.0 SSD controller, the E26. The E31T is based around multiple Arm Cortex R5 cores for realtime operations, and in Phison designs these are traditionally accompanied by special-purpose accelerators that belong to the company's CoXProcessor package. The chip supports Phison's 7th Generation LDPC engine with...
