SATA drives provide the following benefits by transferring datausing serial technology and flexible cables that are thinner and longer than IDE cables:l Improved cable routing facilitates more efficient airflow inside the chassis.l Compact cable connectors save space on the system board and on the hard drive, allowing for more efficient utilization of space inside the chassis.General Drive Installation GuidelinesSATA drives should be connected to connectors labeled "SATA" on the system board. IDE drives should be connected to the connectors labeled "IDE."When connecting a SATA cable, hold the cable by the connector at each end and press firmly into the connector. When disconnecting a SATA cable, hold thecable by the connector at each end and pull until the connector detaches.NOTICE: When removing and replacing drives, be sure to leave the drive data and power cables connected to the system board.NOTE: The 5.25-inch Media Card Reader/floppy drive carrier is not interchangeable with the hard drive carrier.1 CD/DVD drive bays (4) 2 floppy drive/media card reader 3 hard-drive bays (4)
