You can see if you are using DMA, and test speed and other with the follow commands:
For use with ATA disks/ATAPI/USB-ATA
hdparm

For SATA/SCSI/USB-SATA
sdparm

See man pages for more information
example:
man hdparm
man sdparm

Example, if you want to know if you have DMA active for hda unit, you can do some like this:
sudo hdpam -d /dev/hda
If you want to set ON the DMA on hda:
sudo hdparm -d 1 /dev/hda

For test Transfers speed:
sudo hdparm -tT /dev/hda

There are many options.
