Silicon Motion plans to formally introduce its MonTitan SM8466 SSD controller with a PCIe 6.0 x4 host interface at the upcoming FMS 2025 conference next month, according to a leak by ITHome. The new controller will enable drives with sequential read speeds of up to 28 GB/s and random read/write throughput of a whopping 7M IOPS.

Silicon Motion's MonTitan SM8466 SSD controller for enterprise SSD will feature 16 NAND channels supporting all the upcoming types of 3D NAND memory, as revealed by Wallace C. Kou, chief executive of Silicon Motion, in an interview with Tom's Hardware published last month. The controller will be used to build drives with up to 512 TB capacity that will feature sequential read speeds of up to 28 GB/s as well as random read/write performance up to 7M 4K IOPS.
