Conduant Delivers Unparalleled Read/Write Data Rates with M.2 Based Storage Modules for PXI Express Systems

Conduant Corporation, a leader in long-duration high-speed recording and playback systems, today introduced the Big River™ DM-4M.2 3U storage unit delivering up to 4 terabytes of M.2 storage capacity. The DM-4M.2 with a PXIe Gen3 x8 host interface delivers high-speed data rates for sequential writes of 3.6 gigabytes/second and sequential reads of 3.7 GB/s to PXI Express systems. The Big River™ DM-4M.2 3U is designed to provide high speed storage for use in the fields of industrial control and test and measurement.

The single slot design of the Big River™ DM-4M.2 3U storage unit preserves valuable chassis space allowing for maximum storage flexibility and is software RAID configurable. The DM-4 M.2 complies with PXIe Gen3 protocol standards for the highest bandwidth possible and increased read/write performance.

The DM-4M.2 is designed to meet the non-volatile memory express (NVMe) specification for maximum throughput on the PXI Express bus and operates under major operating systems including Windows, Linux, Unix, Solaris and VxWorks.

“Conduant designed the DM-4M.2 to leverage the latest high speed interconnect available using Gen 3 PXIe components,” said founder and CEO, Ken Owens. “The resulting read/write speeds bring a whole new level of performance to PXIe based storage. We’ve taken advantage of the compact form factor of the M.2 for a single slot design and eliminated cable management and data connectors. It’s simple, elegant and offers the highest read/write performance available today.”
