DMA's benefits are two-fold. Firstly, it allows the hard disk direct access to system memory, and secondly, by circumventing the CPU, lesser time is consumed in getting the data transferred. Hard disks and optical units can benefit from using DMA. To enable it, click Control Panel > System, and click on the 'Device Manager' tab. Under the 'Disk Drive' subheading, click on a device and proceed to the Settings tab. Check the 'DMA' tab, click 'OK' and restart the system for the changes to take effect. Note that this only works for drives that have DMA capability.
