This latest Addonics 6G Rack Mount Port Multiplier (PM) connects up to 5 SATA hard drives or SSD to a computer using one eSATA connection at SATA III speed of 6Gbps. The PM is mounted on a rack-mount bracket that fits perfectly into the Addonics family of Storage Tower and many standard drive enclosure with SCSI-I (Centronic 50) punch out. The five drives connected to this PM appears as individual drives to the OS when connecting to a PM compatible eSATA port on a computer. The five drives can be set up as a single RAID volume using the RAID utility of the OS or the host controller.
