AMD Radeon RAMDisk is a free and commercial application for Windows to create a RAM disk -- read memory drive -- from system memory.

Softperfect announced recently that its Ramdisk was no longer available for free. While it is still possible to use version 3.4.8 and earlier for free, it is probably a good idea to look for an alternative unless you want to purchase a commercial license.

A ram disk can be quite useful for certain tasks as it simulates hard drive storage during sessions but is significantly faster than hard drive storage.
