The 5-port HPM-XU is one of the most advanced Port Multipliers in the market. Built on the exact same platform as the HPM-XA, this new port multiplier comes with a built-in eSATA and the lastest USB 3.0 interface. Using the 5-Port HPM-XU, you can connect as many as five SATA hard drives to any system via just a single eSATA or USB cable. The five hard drives can be set up to appear as five individual drives, just like connecting through a USB hub, or appear as a single RAID volume. You can also connect five SATA optical drives such as DVD-RRW or Blu-Ray drives to your system and do simultaneous data copying with this HPM.
