New Silicon Motion SM2524XT chip brings 14 GB/s to mainstream SSDs — 6nm DRAMless controller boasts heavy AI PC optimization and slashes KV cache latency

Silicon Motion's new SM2524XT chip for mainstream SSDs brings read speeds of up to 14 GB/s with four NAND channels supporting transfer rates of 4,800 MT/s. The controller, based on Arm Cortex-R-series cores, does not use DRAM and complies with the NVM 2.0 specification. It supports the latest 3D NAND technologies and features SMI's NANDXtend LDPC ECC technology. The chip boosts random workload throughput by 25%, reduces latency, and improves responsiveness for AI and KV cache operations. Prototype drives based on the SM2524XT will be showcased at Computex, with market availability expected next year.
