Rounding out our Computex 2024 SSD controller news, let's talk about the final major controller vendor at the show: Silicon Motion. Silicon Motion has been somewhat late to the PCIe Gen5 SSD party, as its rival Phison has been offering their high-end PS5026-E26 controller for almost 18 months now. But as Silicon Motion gets ready to make the transition to PCIe 5.0, the company has a trump card up its sleeve: the SM2508 controller, an energy-efficient high-end SSD controller that is intended for lower-power drives.
A PCIe Gen5 x4 controller, SMI's SM2508 boasts a very low active power consumption of 3.5W. Which, installed in an M.2 SSD, is intended to allow drive manufacturers to built 7 Watt (or lower) SSDs, according to the company. The SM2508 is made on TSMC's N6 process technology, which is a 7nm-class fabrication node with an optical shrink, which will make it one of the (if not the) most advanced controllers on the market once it ships. The relatively sophisticated node allows Silicon Motion to pack more cores and more features into its controller while keeping its power consumption in check – not to mention the chip size.
