The DK32EJ series uses high performance sputtered disks, GMR heads, and a rotary type voice coil motor to drive the heads. These features provide high capacity, high speed positioning and high reliability. The DK32EJ-FC uses a SCSI interface as the upper level layer though the physical host interface is changed to Fibre Channel. Therefore, the host can access the FC disk drive with almost same manner as the SCSI disk drive. Some functions dependent on physical interface is different from that of SCSI disk drives.
