What is ramcache?

Ramcache is a technique used in computer systems to improve the performance of hard drives or other storage media. It involves using a portion of the system's RAM as a cache or buffer for frequently accessed data from the hard drive. This means that instead of fetching data from the hard drive repeatedly, the system can access it more quickly from RAM, reducing the time it takes to load frequently used applications, files, and programs. Ramcache is supported by many modern operating systems, including Windows, Linux, and macOS. It can be implemented in various ways, including software and hardware solutions, and can provide significant performance benefits for users who work with large amounts of data.
