Most hard drives either use SCSI interfaces or IDE/ATA interfaces to transfer data from the hard drive to your computer. There are also variations within these family of interfaces.

When it comes to deciding between the two data transfer modes, it depends on the kind of work you will be doing with your computer. For most people IDE/ATA drives will provide the optimum performance at a lower cost. SCSI drives are more expensive and you only start to gain significant advantages when you're using multiple SCSI drives and doing intensive data access due to numerous processes running on your PC. That's why you tend to see SCSI drives being used in high end servers that run multiple tasks simultaneously.
