New Silicon Motion SM2524XT chip brings 14 GB/s to mainstream SSDs

Silicon Motion has unveiled its new SM2524XT SSD controller, fabricated using a 6nm process, delivering up to 14 GB/s read speeds—a significant leap for mainstream SSDs. The chip features four NAND ch... Read original →

The SM2524XT redefines the DRAMless controller category by nearing high-end PCIe 5.0 performance—its 14 GB/s throughput and SCA architecture will force NAND vendors to fast-track 4800 MT/s interface adoption and push rivals away from channel-count scaling. For Taiwan, China-based Silicon Motion, reliance on TSMC’s 6nm node ensures yield but exposes it to U.S. export controls; if 6nm falls under expanded restrictions, cost volatility looms. Samsung and Phison will likely counter with HBM-buffered designs or in-house IPs, yet matching its power-performance efficiency before 2025 is improbable. Within 18 months, AI PC demands for low-latency KV cache access will make such controllers OEM defaults, driving QLC NAND penetration in client SSDs beyond 40% and redrawing the consumer storage cost-performance frontier.
