A RAMDisk, also known as a RAM drive or virtual drive, is a software-based storage device that uses a portion of your computer's RAM to store data. Unlike traditional hard drives or solid-state drives (SSDs), which use spinning disks or flash memory to store data, a RAMDisk uses volatile memory (RAM) to store data temporarily. This allows for extremely fast read and write speeds, making it ideal for applications that require high-performance storage.
