Disk caching applies the same principle to the hard disk that memory caching 
applies to the CPU. Frequently accessed hard disk data is stored in a separate segment 
of RAM in order to avoid having to retrieve it from the hard disk over and over. In this 
case, RAM is faster than the platter technology used in conventional hard disks. This 
situation will change, however, as hybrid hard disks become ubiquitous. These disks 
have built-in flash memory caches. Eventually, hard drives will be 100% flash drives, 
eliminating the need for RAM disk caching, as flash memory is faster than RAM.
