Silicon Motion Technology Corporation ("Silicon Motion"), a global leader in designing and marketing NAND flash controllers for solid-state storage devices, today announced it will showcase its latest storage innovations for AI Factory, Edge AI, and Physical AI applications at Future of Memory and Storage (FMS) 2026, taking place August 4 to 6 in Santa Clara, California, at Booth #315.

As AI evolves beyond large language model training toward Agentic AI, real-time inference has become increasingly dependent on fast, predictable data access. Emerging storage requirements for KV cache and Agentic AI applications demand storage solutions that maximize acceleration while maintaining low latency and consistent performance. Silicon Motion will showcase five major product lines addressing the evolving storage requirements across the three AI segments, supporting enterprise infrastructure, edge computing, embedded devices, and automotive platforms:

Silicon Motion Inc (SMI) showcased their latest SSD controller portfolio at Computex 2026. We begin our tour with the consumer-segment SM2524XT, a new DRAMless PCIe Gen 5 SSD controller, with support for the NVMe 2.1 protocol. This controller features 4 flash channels and 16 CEs for up to 4800 MT/s per channel, and is designed for mid-range Gen 5 NVMe SSDs. SMI built the controllers on the TSMC 6 nm foundry node. Drives based on this controller can offer sequential read speeds of up to 14 GB/s, with up to 12 GB/s sequential writes, with up to 2.2 million IOPS random access. The controller's own TDP is rated at 2.5 W in active mode, and as low as 1 mW in PS4 standby. The controller supports all popular 3D TLC and QLC NAND flash memory types.

SMI also showed us their first PCI-Express Gen 6 SSD controller for next-generation enterprise SSDs, the SM8466. This controller is designed to offer "near GPU storage performance," augmenting GPU memory, and giving you the ability to run larger parameter LLMs. The controller features a PCI-Express 6.0 x4 host interface (256 Gbps per direction, or bandwidth comparable to PCI-Express 4.0 x16). It features 16 channels with 8 CEs, each channel runs at 4800 MT/s. While not mentioned, SM8466 is likely to support NVMe 2.3, which lays the foundation for computational storage. It supports all relevant enterprise features for this role. The controller will drive SSDs with capacity of up to 512 TB, supporting 3D TLC and QLC NAND flash. As for performance, the controller is being prepared to offer sequential transfers of up to 28 GB/s, and random access performance of up to 7 million IOPS.

Silicon Motion Technology Corporation (NasdaqGS: SIMO), a global leader in NAND flash controllers for solid-state storage devices, today announced the SM2524XT, a next-generation PCIe Gen 5 DRAMless SSD controller purpose-built for AI inference and KV Cache-intensive workloads. The SM2524XT leverages a new four-processor-core architecture with PCIe Gen 5 x4 and NAND interface speeds up to 4,800 MT/s to achieve sequential read speeds up to 14 GB/s and industry-leading random performance of up to 2.5 million IOPS.

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.

Silicon Motion revealed the first details of its first consumer PCIe 6.0 NVMe SSD controller at the Future of Memory and Storage (FMS) conference this week, alongside a new DRAM-less PCIe 5.0 controller that appears to rival the SM2508 in terms of performance. The new PCIe 6.0 controller is currently only known under the code name Neptune, but Silicon Motion is promising 25 GB/s or better sequential read speeds and up to 3.5 million IOPS. However, this hinges on the use of 4800 MT/s NAND flash in an eight channel configuration. Neptune is expected to launch sometime in 2028, which means you have plenty of time to save up.

As for its new DRAM-less PCIe 5.0 controller, it goes under the SM2524XT model name and features 14 GB/s or better sequential read speeds and 2.5 million IOPS, which is identical to Silicon Motions flagship SM2508 controller. However, this does require faster 4800 MT/s NAND, so it's not likely we'll see that type of performance from the first generation of drives based on the SM2524XT, as it has a 4-channel NAND interface vs. an eight channel interface on the SM2508. The SM2524XT is expected to launch some time next year. A new common feature for both of the new controllers—that they share with the SM2504XT—is support for Separate Command Architecture (SCA) which allows for commands and address transmission paths to be handled in parallel instead of having to deal with them sequentially, which should reduce latency and increase available bandwidth to the NAND.
