Computer Architecture and Maintenance (G-Scheme-2014)
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.
