A RAM disk is a virtual drive created in a free area of RAM that the OS sees as a normal local hard drive. The advantage of RAM Drive is its very high read/write speed (up to 10 times faster than SSD and up to 2-3 times faster than NVME M.2). A RAM disk can be used on computers with large amounts of RAM to store cache and temporary application files. Mostly RAM drive is used to store browser cache, temporary SQL databases, graphics or video rendering application cache, etc. This improves application performance and significantly offloads physical disks. The contents of the RAM disk are usually erased when the computer is restarted.
