At FMS 2024, Phison gave us the usual updates on their client flash solutions. The E31T Gen 5 mainstream controller has already been seen at a few tradeshows starting with Computex 2023<\/a>, while the USB4 native flash controller for high-end PSSDs was unveiled at CES 2024<\/a>. The new solution being demonstrated was the E29T Gen 4 mainstream DRAM-less controller. Phison believes that there is still performance to be eked out on the Gen 4 platform with a low-cost DRAM-less solution.<\/p>\n

Compared to the E27T, the key update is the use of a newer LDPC engine that enables better SSD lifespan as well as compatibility with the latest QLC flash, along with additional power optimizations.<\/p>\n

The company also had a U21 USB4 PSSD reference design (complete with a MagSafe-compatible casing) on display, along with the usual CrystalDiskMark benchmark results. We were given to understand that PSSDs based on the U21 controller are very close to shipping into retail.<\/p>\n

Phison has been known for taking the lead in introducing SSD controllers based on the latest and greatest interface options – be it PCIe 4.0, PCIe 5.0, or USB4. The competition is usually in the form of tier-one vendors opting for their in-house solution, or Silicon Motion stepping in a few quarters down the line after the market takes off with a more power-efficient solution. With the E29T, Phison is aiming to ensure that they still have a viable play in the mainstream Gen 4 market with their latest LDPC engine and supporting the highest available NAND flash speeds.<\/p>\n<\/p><\/div>","protected":false},"excerpt":{"rendered":"
