Once installed, run the Quick Bench test and check the results as pictured below.
The graph displays the read speed. The outer sectors of a drive are always faster than the center of the disk. As the drive fills up with data, the drive slows down. For maximum performance the database.nv2 files should be parked near the beginning or outer sectors of the drive (this can be achieved with defragmentation settings).

Hard drive performance is a combination of the physical drive, i.e. the transfer rate, the interface and bus speed, i.e. the I/O controller hub, EIDE, SATA or SCSI and the operating system's I/O drivers. All these components need to be matched or else poor performance will be the result.
