RAVE currently has multiple C4ISR customers that have made the transition to the faster speeds. Additionally, our Signal Processing customers have been taking advantage of the performance increase. They are now able to detect, identify and geolocate signals throughout the electromagnetic spectrum at NVMe speeds.
We are in the process of building an aircraft deployed High Speed Recording server that will take advantage of the faster speeds NVMe SSD’s offer. This 4U Rackmount Server will have the capability to support up to 8 Removable NVMe drives.
The chart below highlights performance gains of NVMe over more traditional SSDs.
