    The newest, and fastest NVMe drives from Samsung cannot use Rapid Mode. They also don’t need to. So if you’re using a 960 or 970 series SSD,

    What is Rapid Mode?

    Achieve over 2X faster performance through intelligent DRAM caching of data, for read acceleration and write optimization.

    You can’t physically make the drive faster, as the read/write speeds are bound by the limitations of the hardware. Rapid Mode instead uses intelligence and other resources in your PC, namely the RAM, to cache files for quicker access and a more streamlined write process.

    What is RAPID Mode Technology
    RAPID mode is paired exclusively with Samsung SATA SSDs (840 series and above) and available as a feature of the accompanying Samsung SSD Magician Software Toolset (version 4.2 and later). When configured correctly, RAPID mode functions as a filter driver within the Windows storage stack. The filter driver continuously monitors all storage-related activity between the Operating System (OS), user applications and the SSD. RAPID mode analyzes all system traffic, leveraging extra system resources such as DRAM/CPU to dynamically provide read acceleration via intelligent caching of “hot data” and write optimization.

    The concept behind RAPID mode: Your computer “learns” from your computer habits. It recognizes frequently launched applications and attempts to make them instantly available when you first login to your system. Helping applications, databases, webpages, and general use functions to launch quickly due to high usage.

    Hot Data

    Read acceleration technology in RAPID mode leverages spare system DRAM and CPU resources to manage a change in “hot data”. As your system stores hot data in memory, system performance is improved as similar requests for that data are performed; then, data is served directly from DRAM rather than the system having to pull from a storage device. Latency, throughput and overall daily user experience for the most active data are improved. Taking a simple approach to caching the most recently accessed data, RAPID mode operates almost as an extension of the OS cache. RAPID mode handles not just new data, but very carefully takes into account frequency of access, file types, system status, RAM availability, etc. RAPID mode may exclude certain data from the cache based on a variety of factors by excluding certain data not regularly used. This prevents unnecessary data from polluting the cache and allows us to keep the memory footprint to a minimum. Files that RAPID mode deems meaningless to cache (such as large media files) are dismissed.

    Hot data is cumulative and persistent across multiple sessions and reboots so that if you have been working on a specific file or application you will be able to access critical data faster as well.
