5X1 Internal SATA Port Multiplier (PM)

The Addonics 5X1 Internal SATA Port Multiplier (PM) enables SATA hard drives to be configured for a wide range of storage applications. Designed to be mounted in the PCI bracket of any standard desktop, low profile system or rack mounted system, the Internal Port Multiplier can combine up to 5 SATA hard drives into a single onboard SATA port or on an add-in controller. The 5 drives can be set up as individual drives, as a RAID set or with JBOD to become one large hard drive depending on the controller. When multiple PMs are combined with an Addonics 4-Port SATA controller*, you can attach internally a whopping 20 SATA hard drives to your computer via 1 controller!
