Run the command hdparm -t -v /dev/hda (check man pages for
options). Without the -d flag to set DMA , my DMA 33 drive tested at about
3MB/sec read speed. With the dma set -on, my speed jumps to about 17 to 18
MB/sec for reads. You can set other options to try for more improvement but
enabling DMA gives the biggest jump.
