Phison Introduces E29T Gen 4 Controller for Mainstream Shopper SSDs

At FMS 2024, Phison gave us the similar earlier updates on their shopper flash decisions. The E31T Gen 5 mainstream controller has already been seen at quite a few tradeshows beginning with Computex 2023, whereas the USB4 native flash controller for high-end PSSDs was unveiled at CES 2024. The mannequin new resolution being demonstrated was the E29T Gen 4 mainstream DRAM-less controller. Phison believes that there’s nonetheless effectivity to be eked out on the Gen 4 platform with a low-cost DRAM-less resolution.

As in contrast with the E27T, the mandatory issue change is the utilization of a additional moderen LDPC engine that allows bigger SSD lifespan together with compatibility with the most recent QLC flash, together with extra energy optimizations.

The corporate furthermore had a U21 USB4 PSSD reference design (full with a MagSafe-compatible casing) on current, together with the similar earlier CrystalDiskMark benchmark outcomes. We obtained to know that PSSDs primarily based on the U21 controller are very shut to move into retail.

Phison has been acknowledged for taking the lead in introducing SSD controllers primarily based on the most recent and best interface picks – be it PCIe 4.0, PCIe 5.0, or USB4. The rivals is usually contained in the form of tier-one distributors choosing their in-house resolution, or Silicon Movement stepping in quite a few quarters down the freeway after the market takes off with a extra power-efficient resolution. With the E29T, Phison is aiming to make it doable for they nonetheless have a viable play all through the mainstream Gen 4 market with their newest LDPC engine and supporting the best in the marketplace NAND flash speeds.
