Phison unveils world's first mainstream Gen5 SSD and native USB4 controller at CES 2025

Phison has plenty to show at CES 2025, with the announcement of the world's first mainstream Gen5 SSD with the introduction of the PS5031-E31T, and the world's first native USB4 controller with the PS2251-21 (U21).

The new Phison PS5031-E31T is the first DRAM-less PCIe Gen5 SSD controller that pushes over 10GB/sec reads, which the company says that this cost-effective SSD controller will bring premium-level performance, to cost-conscious customers. The new E31T Gen5 SSD controller is fabbed on the TSMC 7nm process node, is DRAM-less, has 4-channel with 16 CEs, and will boast capacities of up to 8TB.

We have sequential performance of up to 10.3GB/sec (10,300MB/sec) reads, and up to 9.5GB/sec (9500MB/sec) writes, with random performance of up to 1300K IOPS read, and up to 1600K IOPS write. One of the big pushes here from Phison is the battery life out of the new E31T SSD controller, with some decent battery life gains that will not just save system power, but generate less heat and still sustain that 10GB/sec+ performance.
