It appears that Silicon Motion is ready to start competing with Phison in the PCIe 5.0 NVMe SSD controller market, as the company has shown a new controller at the Flash Memory Summit 2023 which should give Phison a run for its money. The SM2508 as the controller is called is set to be the most power efficient PCIe 5.0 NVMe controller to date, with a power consumption of 3.5 W, which is in line with most PCIe 4.0 SSD controllers. This still means that a decent heatsink will be needed, but not active cooling or massive heatsinks that we've seen on the current crop of PCIe 5.0 drives based on Phison's E26 controller.
Silicon Motion also appears to have the Phison E26 beat, in terms of performance, as the SM2508 promises to deliver sequential read and write speeds of up to 14 GB/s. Random performance is rated at 2.5 million IOPS read and 2.4 million IOPS write. To get the most out of the SM2508 2400 MT/s or faster NAND flash is going to be needed to deliver the claimed performance figures though, but according to Anandtech, the SM2508 is future proofed by supporting NAND flash speeds of up to 3600 MT/s, so we might see faster drives based on the controller once faster NAND appears, such as SK Hynix new 321-layer NAND, which is scheduled for a 2025 introduction. The SM2508 on the other hand is said to be launching at the end of this year or early 2024.
