RAMDisk

RAMDisk is Freeware (up to 4GB disk size). It creates a virtual RAM drive, or block of memory, which your computer treats as if it were a disk drive. By storing files and programs into memory, you can speed up internet load times and disk-to-disk activities, accelerate databases and reduce compile times. Save and load features allow RAMDisk to appear as persistent storage, even through reboots.
