Silicon Motion unveils new SM2524XT PCIe 5 SSD Controller

Silicon Motion’s newest PCIe 5.0 SSD controller is 25% faster than its predecessor and much more efficient

Silicon Motion has unveiled its new SM2524XT PCIe 5.0 SSD controller, a DRAMless controller that utilises a new 4-processor core architecture and supports new 4800 MT/s NAND chips.

This new controller can deliver 14 GB/s speeds over a PCIe 5.0 x4 interface and deliver 2.5 million IOPS of random performance. Overall, this SSD controller deliver 25% more performance per watt than its predecessor and 25% more random I/O performance. This reduces latency and shortens response times. That’s good for all workloads, be it consumer workloads or AI workloads.

Built on TSMC’s advanced 6 nm process technology, the SM2524XT delivers up to 25 percent higher performance per watt compared to the previous generation controller, sustaining peak random I/O throughput even under the most demanding thermal and power constrained conditions. Against the previous generation controller, the SM2524XT improves random performance by up to 25 percent, slashing latency and accelerating response times for the highly fragmented data access patterns that define KV Cache and AI inference workloads.

The SM2524XT SSD controller is built using TSMC’s 6nm technology and supports Silicon Motion’s Separated Command Address (SCA) technology, advanced FTL scheduling, and NANDXtend LDPC ECC technologies. These improve data processing efficiency, reduce latency interruptions, and help to maintain consistent performance during sustained workloads.

Overall, the Silicon Motion SM2524XT is designed to deliver greater efficiency and stronger sustained performance. Latency reductions also help to make systems using this SSD feel snappier. It also helps users get the most from this SSD under sustained workloads, such as AI inference.
