Drives; General Drive Installation Guidelines - Dell OptiPlex 755 User Manual

Drives

Your computer supports:
• One SATA (serial ATA) hard drive
• One 3.5-inch drive bay (to support a floppy drive, media card reader, or optional second SATA hard
drive)
• One SATA optical drive
• One eSATA drive (with optional bracket)
NOTE:
Due to the limited number of drive bays and controllers on this computer, you will not be able to connect all
supported devices at once.
NOTE:
If you will be operating your computer without an optical drive or a 3.5-inch device (floppy drive or media
card reader) installed, the appropriate drive bay insert must be installed in place of the drive. Contact Dell if you
need a drive bay insert.
