The official release of the SM2508 SSD controller from Silicon Motion took place at the Flash Memory Summit 2024 conference. It will serve as the basis for solid-state drives with a PCI Express 5.0 x4 interface and stands out from its analogues with its low “appetites”. As Silicon Motion notes, the power consumption of the entire SSD based on the new platform will be less than 7 W. This, for example, will allow them to be used in laptops without worrying about excessive heating.
Silicon Motion managed to achieve high energy efficiency indicators, among other things, thanks to the transition to TSMC 6-nm technology. The SM2508 controller uses four ARM Cortex-R8 cores, is compatible with the NVMe 2.0 protocol, supports eight NAND channels with a speed of 3600 MT/s and an external DDR4/LPDDR4 buffer. The new platform can be found in drives with 3D NAND TLC/QLC chips.
In terms of speed, the company claims read speeds of up to 14.5 GB/s and write speeds of up to 14 GB/s for the SM2508-based SSD, as well as a maximum performance of 2.5 million IOPS.
The Silicon Motion SM2508 SSD controller is scheduled to enter mass production next quarter, with solid-state drives based on it expected to hit the shelves some time after that.
