Phison is set to launch its E37T SSD controller, which is the first DRAM-less controller to fully utilize the PCIe Gen5 interface, achieving impressive read speeds of 14,900 MB/s and write speeds of 13,000 MB/s. This innovative design consumes less than a third of the power compared to previous DRAM-infused models, operating at just 3.4W. The E37T not only matches the performance of high-end SSDs but also provides a more affordable option for consumers facing rising SSD prices due to increased demand from AI applications. Phison's Technical Marketing Director, Chris Ramseyer, noted that the company anticipated the challenges posed by high DRAM prices and proactively developed the E37T to cater to both performance enthusiasts and gamers. Early reviews indicate some mixed results, particularly regarding performance on specific platforms like the PS5, but these issues are expected to be resolved before the product's market release later this year.
