Silicon Motion Introduces the SM689 and SM681 FerriSSDs

Another Innovation from Silicon Motion

Last year, Silicon Motion announced their first single-chip 3D NAND SSD. Now they are announcing that they have the world’s first PCIe NVMe single-chip SSDs with Enterprise-grade data protection features. The SM689 and SM681 joins the SM601 (PATA) and SM619 (SATA) solutions in the Silicon Motion FerriSSD family. Just like the previous drives, the SM689 and SM681 are ideal for computing applications in industrial, commercial, enterprise and automotive end-markets.

What Features Does the SM689 and SM681 FerriSSDs Have?

Both drives share similar features, including the following.

The distinction however, is that the SM681 is a DRAMless solution. In terms of performance, the SM689 supports PCIe Gen 3×4 interface while SM681 supports PCI Gen 3×2 interface. This results in sequential read speed of up to 1.45GB/s and sequential write speed of up to 650MB/s.

Silicon Motion intends to show off these drives in person at the Embedded World Exhibition in Nuremberg, Germany from February 27 through March 1 2018.
