6. Disk Drive Performance Hacks > 65. Speed Up DOS with SMARTDRV

Speed Up DOS with SMARTDRV

You can add a boost to disk performance with the DOS SmartDrive program.

Caching or reading data from a hard drive and storing it in RAM is one method to speed up disk drive performance. Most disk drives have at least some RAM dedicated to buffering data between the disk and the data cable, some disk drive interface cards and chips provide data caching, and even DOS and Windows provide disk caching. DOS’s own SmartDrive program, SMARTDRV.EXE, provides a tremendous performance boost for DOS systems. (If you install SMARTDRV for a Windows 95-98 system, Windows unloads SMARTDRV at startup. With or without SMARTDRV for DOS, Windows provides its own disk caching driver, VCACHE, to speed up disk performance [Hack #66] . For Windows Me and later, the device drivers and VCACHE provide disk caching.)
