Installing RAM Disk

Information:
RAMDisk is a program that takes a portion of your system memory and uses it as a disk drive. What is the benefit? In a word: SPEED! An additional feature of a RAMDisk is that it will never wear out. You can access it at maximum bandwidth 24/7/365 without fear of mechanical failure, or fragmentation (a RAMDisk can become fragmented just like any other disk, but it does not take a performance hit like a physical disk does when it becomes fragmented). A RAMDisk operating at maximum bandwidth does not produce excessive heat, noise or vibrations.

Most users use RAMDisk to speed up applications like:

• Databases
• Internet Explorer and Firefox cache for faster web surfing
• Audio and Video editing
• CAD programs
• Photoshop Scratch Disk
• Speeding up CD duplication
• Games
• SETI processing
• TEMP files
• Swap space
• Web server cache
• Custom applications with high I/O, high bandwidth, or high security requirements
