Silicon Motion at the 2025 Computex showed off its latest SSD and flash storage controller products. The star-attraction is the company's new SM2504XT, a DRAMless client NVMe SSD controller. The chip is built on the TSMC 6 nm process, with a power draw of just 2.4 W when active, and 1 mW when idling. The controller features 4 flash channels with 16 control elements, each with up to 3600 MT/s transfer speeds. It supports 3D TLC and 3D QLC NAND flash types from popular vendors. The reference SSD based on the SM2504XT was shown offering maximum sequential read speeds of 11.5 GB/s, and max sequential writes of 11 GB/s; with 1.7 million IOPS 4K random reads, with up to 2 million IOPS 4K random writes.
Next up, is the SM8366 enterprise SSD controller designed for PCI-Express Gen 5 x4 host interface across popular form-factors such as U.2, E1.S, and E3.S, including some extreme capacity drives. A demo drive showcased in the Silicon Motion booth had the NAND flash components spanning two PCBs that are interconnected by a ribbon cable. There are other interesting onboard devices such as DRAM cache, and capacitor-based power-loss protection. This controller was shown posting sequential read speeds of 14710 MB/s with QD128, and sequential writes of 3444 MB/s with QD128; and a sensational 3 million IOPS 4K random reads at QD512.
Pictures of the SM8366 and its performance follow.
