Port Multiplier

Port Multiplier (PM) allows for multiple SATA drives (up to 4) to be connected to a
single SATA host port. PM allows for easy, cost-effective storage scalability both inside
and outside the PC or server. It is commonly used to connect a multi-drive SATA/eSATA
hard drive enclosure/backplane using a single cable. This greatly expands the storage
capabilities of the SATA controller beyond its normal port count.
Note: Only the two SATA ports on the card can use the Port Multiplier feature. Only one
of these SATA ports can use the Port Multiplier feature at a time. The card supports up
to 4 drives connected via Port Multiplier, and 7 drives total (including two mSATA SSD).
Mac OS does not support Port Multiplier.
