Drives
Your computer supports:
l Up to Two 3.5-inch or up two 2.5-inch SATA (Serial ATA) hard drives
l One 3.5-inch floppy drive or media card reader
l Two 5.25-inch SATA optical drives
l One eSATA drive (external, connector on back panel)
General Installation Guidelines for SATA Devices
SATA connectors on the system board are labeled SATA0, SATA1, SATA2, and SATA3.
Hard drives must be connected to the lower numbered SATA connectors, while any other SATA devices (like an optical drive) must be connected to the
remaining SATA connectors numbered higher than the one that the hard drive(s) is connected to. For example, if you have two SATA hard drives and one SATA
optical drive, connect the two hard drives to the SATA0 and SATA1 connectors, and connect the SATA optical drive to the SATA2 connector. (See
System Board
Components for the location of SATA connectors on the system board.)
Connecting Drive Cables
When you install a drive, you connect two cables—a DC power cable and a data interface cable—to the back of the drive.
Data Interface Connectors
NOTE: If you are removing or adding a device that affects the hardware or RAID configuration of the system, BIOS settings may need to be changed.
Refer to the Dell™ Technology Guide for more information.
