Add 4 Internal SATA III (6Gbps) ports to a computer through a PCI Express x2 slot. The PEXSAT34RH 4-Port PCI Express SATA III Controller Card adds 4 AHCI SATA III ports to a computer through a PCIe slot (x2), delivering multiple internal 6Gbps connections to high-performance hard drives and Solid State Drives (SSDs), all from a single PCIe expansion slot.The PCIe SATA controller card features Port Multiplier (PM) support on each port, which enables multiple SATA drives to be connected through one of the ports over a single cable, for a total of 7 simultaneous drive connections - (Connect up to 4 drives through PM on one port, and a single drive to each of the remaining 3 ports).Supporting RAID 0, RAID 1 and 1+0 configurations, this versatile PCI Express SATA RAID card includes an onboard heatsink to dissipate heat build-up, to help maintain peak operating performance even at full capacity.
