Silicon Motion Unveils Next-Gen SSD Controllers
Silicon Motion has provided a sneak peek into its upcoming consumer PCIe 6.0 NVMe SSD controller at the recent Future of Memory and Storage (FMS) conference. Alongside this, the company also introduced a new DRAM-less PCIe 5.0 controller, the SM2524XT, which is set to compete with the performance of the SM2508. The PCIe 6.0 controller, codenamed Neptune, is expected to deliver impressive sequential read speeds of 25 GB/s or higher and up to 3.5 million IOPS. However, achieving these speeds will require the use of 4800 MT/s NAND flash in an eight-channel configuration. Neptune is slated for release in 2028.
On the other hand, the SM2524XT boasts sequential read speeds of 14 GB/s or better and 2.5 million IOPS, similar to the flagship SM2508 controller. This controller also relies on 4800 MT/s NAND, but with a 4-channel NAND interface compared to the eight-channel interface of the SM2508. The SM2524XT is anticipated to hit the market next year.
Both controllers, including the SM2504XT, now support Separate Command Architecture (SCA), enabling parallel handling of commands and address transmission paths. This feature is expected to reduce latency and enhance available bandwidth to the NAND.
