Enterprise-grade data protection on a single-chip SSD

From Silicon Motion Technology Corporation come the FerriSSD single-chip SSDs that feature a PCIe Gen 3 NVMe 1.3 interface for high-performance mission critical applications.

The SM689 supports PCIe Gen 3×4 interface while the SM681 supports PCI Gen 3×2 interface – exhibiting sequential read speed of up to 1.45GB per second and sequential write speed of up to 650MB per second. Both products can support multiple capacity configurations ranging from 16GB to 256GB and include enterprise-grade advanced data integrity and reliability capabilities using Silicon Motion’s proprietary end-to-end data protection, ECC and data caching technologies.

The SM689 and SM681 are the newest members of the FerriSSD family which includes the PATA (SM601) and SATA (SM619) solutions targeted at embedded computing applications in industrial, commercial, enterprise and automotive end-markets.

FerriSSD single-chip SSDs are customisable via firmware, and offer enhanced reliability and robust data integrity features that are essential for the extreme operating environments of these applications.   

“The FerriSSD storage solutions are popular with automotive and industrial designers, allowing them to replace a hard disk drive with reliable solid-state alternatives,” said Nelson Duann, senior vice-president of marketing and OEM business at Silicon Motion. “The addition of a PCIe NVMe interface will enable significantly better performance for applications such as AI and autonomous driving.”

Silicon Motion’s SM689 and SM681 FerriSSDs support enhanced reliability and data integrity features for use in demanding automotive, commercial, enterprise and industrial applications. Its set of features includes: end-to-end data path protection, which applies error correction code (ECC) to the SSD’s SRAM and DRAM buffers as well as to the primary NAND Flash memory array, DRAM data cache to ensure data programming and enable data redundancy, without delaying host processor operations, hybrid zone which enables a single disk to be partitioned into single-level cell (SLC) and multi-level cell/three-level cell (MLC/TLC) zones, enabling faster access speeds and data retention.

Intelligent Scan/DataRefresh protects against the higher data loss from operating at high temperatures. NANDXtend technology, incorporating Silicon Motion’s proprietary 4th generation high-performance LDPC ECC engine with RAID, helps ensure better data integrity even in extreme physical environments.
