Disk Caching
A disk cache is used to increase hard disk performance. It sets aside a portion of
the computer’s system memory where frequently used data from the hard disk is
temporarily stored. Because typical memory access time is several thousand
times faster than disk access time, a disk cache can yield a phenomenal increase
in your computer’s overall performance.
The SMARTDRV.EXE program included with MS-DOS is an example of a
program that can be used to implement a disk cache. This program allows you to
specify the amount of memory to be used as a disk cache. Refer to a DOS manual
for instructions on the SMARTDRV.EXE program. Windows 95, 98 and NT 4.0
have a built in cache utility.

whereas a memory cache is normally used to speed up access to DRAM.
