Why PCIe NVMe FerriSSD?

Easy to use

  • Plug & Play only requires format/fdisk prior to use
  • Small footprint for space-limited design

Lower total cost of ownership

  • Rugged & Reliable (no moving parts)
  • Eliminate requalification cost from NAND generation change
  • Cost saving with low density FerriSSD, HDD are typically > 160GB capacity

Eliminate down time

  • Supports self-monitoring, analysis and reporting technology commands (S.M.A.R.T.)
  • Support End-to-end data path protection with recovery algorithms such as IntelligentScan with DataRefresh
  • Equipped with 4th generation LDPC ECC engine with SMI Group Page RAID
  • Field programmable firmware available

Meet the SM689 & SM681 Series

The SM689 and SM681 of the PCIe NVMe FerriSSD family are optimally designed for high-performance mission critical applications.

The SM689 supports embedded DRAM with Data Redundancy using the PCIe Gen3 x4 interface, exhibiting sequential read speeds of up to 1.45GB/s and sequential write speeds of up to 650MB/s.

The SM681 DRAM-Less series supports the PCIe Gen3 x2 interface and features the best balance of saving/performance and cost-savings from eliminating DRAM while maintaining DRAM-like performance via HMB (Host Memory Buffer).

Both available in 3D TLC/MLC/SLC modes, supporting capacity configurations ranging from 4GB to 256GB and includes enterprise-grade advanced data integrity and reliability, using Silicon Motion's proprietary end-to-end data protection, ECC and data caching technologies.
