At the ongoing Future Memory & Storage conference, Silicon Motion gave a sneak peek on its next-generation flagship SSD controller with a PCIe 6.0 x4 interface for client PCs. The new controller is codenamed Neptune and will offer the rather unprecedented sequential read performance of over 25 GB/s. Unfortunately, PCIe Gen6 SSDs for client PCs are still a few years away.
Silicon Motion's Neptune controller with a PCIe 6.0 x4 interface is the industry's first announced PCIe Gen6 SSD platform for client PCs . It will feature eight NAND channels supporting interface speeds of up to 4800 MT/s, targeting next generation 3D NAND memory with over 400 active layers. The Neptune's controller will enable compatible drives to attain sequential read speeds of over 25 GB/s and random performance of 3.5 million IOPS, which is dramatically higher compared to the best client SSDs with a PCIe 5.0 x4 interface.
