Phison makes PCIe 5.0 storage mainstream with their cool-running E31T controller

The era of large PCIe 5.0 SSD heatsinks is coming to an end – Phison is ready to make PCIe 5.0 storage mainstream

At Computex 2024, Phison were demoing a PCIe 5.0 SSD that was cooler running and used less power than any of their prior PCIe 5.0 SSDs. Thank to their new 7nm PS5031-E31T SSD controller, Phison could deliver 10 GB/s of SSD performance on a mainstream SSD. PCIe 5.0 storage no longer requires large heatsinks or a larger power budget.

To highlight the low-power nature of this SSD, Phison were showcasing this SSD within a laptop. Until now, PCIe 5.0 devices were best suited to desktop systems. On desktop, higher power use and higher thermals are less of an issue than it is on laptops. On laptops there is typically less airflow for cooling and less room for heatsinks. Beyond that, an SSD with a high power draw is bad for battery life. Now, thanks to the Phison E31T controller, those problems have bee addressed.

With their new PS5031-E31T SSD controller being a DRAM-less controller with only four NAND channels, it is clear that Phison’s E26 SSD controller is still their flagship PCIe 5.0 controller. That said, Phison’s new E31T controller appears to be highly capable, not just because of its maximum sequential speeds, but because of Phison’s plans to support up to 8TB of NAND using this controller.

At Computex 2024, Phison and Sabrent also showcased their ultra-fast 64TB Apex X16 Rocket 5 Destroyer SSD.
