2X Throughput

Up to 800k IOPS

Up to 16 TB Storage

High Throughput with PCIe 4.0 Interface

Codensity is delivering tomorrow’s Peripheral Component Interconnect (PCI) throughput today, with support for the PCIe 4.0 x4 interface specification. With Codensity D400 SSD, read-intensive and streaming applications benefit from 2x the throughput per PCIe lane relative to any PCIe 3.0 SSD product on the market today.

NVMe R1.3 delivers high performance control of SSD memory

Codensity D400 SSDs support the latest NVMe R1.3 features to maximize the I/O performance and speed of solid state non-volatile memory (NVM) technology. Its streamlined queuing protocol, combined with optimized command set interface, delivers superior performance and lower latencies compared to SATA or SAS data storage technology.

Enterprise-class Capacity, Performance, and Reliability

The Codensity D400 supports up to 16TB of raw storage, with up to 800k random I/O processes per second (IOPS), 6 GB/s throughput, 100 µs read latency, and 10 µs us write latency, to deliver SSD storage performance for mission-critical enterprise and cloud applications. A comprehensive Error Correction Code (ECC) implementation overcomes the inherent bit storage reliability challenges with NAND Flash technology, delivering a high-reliability SSD solution with mean time to failure (MTTF) of 2 million device hours.

H.264/H.265 video processing for scalable video storage

Video content is one of the largest consumers of network bandwidth and cloud storage capacity. Inside each D400 SSD is the Codensity G4 SSD Controller SoC with on-chip H.264/H.265 encoders and processors, allowing Codensity D400 SSDs to support advanced video storage capabilities. For example, H.264 content can be transcoded and compressed into H.265 format, saving 50% SSD storage capacity with minimal loss of video quality. When H.265 video is later retrieved, the video can be transcoded back to H.264, or pre-processed into different resolutions, bandwidth, or framerates, making Codensity SSD an innovative solution for scaling video storage and distribution.

Flexible SSD architecture supports optimizations for data-intensive applications

The underlying Codensity G4 SSD controller SoC technology is based on a flexible multi-processor architecture with sixteen programmable flash control channels, allowing NETINT engineers to work with application developers and storage architects to optimize Codensity D400 SSD storage solutions and Flash device options for your application performance priorities.
