Although SATA is still a dominant interface in embedded and NetCom systems, the future belongs to PCIe. PCIe breaks the bandwidth limitations of SATA and offers flexible solutions with multiple lanes that can be combined.
An important innovation to increase the performance is the new protocol NVMe, which has been designed specifically for Non Volatile Memory. It reduces significantly the latency of read and write requests by using more efficient commands.
With higher performance also comes higher power consumption, especially with the common 4-lane configuration.
The Swissbit N-10m2 module, a PCIe Gen3 / NVMe 1.2 module, only uses 2 PCIe lanes and reduces the power consumption without sacrificing performance. Even if only operated with one single PCIe lane, the performance still exceeds the SATA limits.
