    Marketing Information
    Add 1 internal mSATA slot and 3 internal SATA III (6Gbps) ports to a computer through a PCI Express x2 slot. The PEXMSATA343 3-Port PCI Express 2.0 SATA Card with HyperDuo adds an internal mSATA SSD (Solid State Drive) slot plus three internal SATA III ports to your computer through a PCIe x2 slot, adding multiple 6 Gbps internal connections that enable you to improve the overall speed and storage capacity of your computer by connecting high-performance SSDs and hard drives.

    Featuring HyperDuo technology, the SATA card offers SSD auto-tiering which lets you balance the performance advantages of SSD storage with the cost-effectiveness and large capacity of standard hard drives. By combining SSD and HDD drives into a single volume (up to 3 SSD + 1 HDD), HyperDuo discreetly works in the background to identify and move frequently accessed files to the faster SSD drive(s) for improved data throughput - up to 80% of SSD performance! (Note: The HyperDuo automatic storage tiering feature is compatible with Windows® XP, Vista, 7 and 8 only)

    The PCIe SATA controller card offers Port Multiplier (PM) support, so multiple SATA drives can be connected over a single cable, for a total of 7 drives (Up to 4 drives through PM on one port, and a single drive to the remaining 2 ports and mSATA slot). Plus, the SATA controller card offers an effective hardware RAID solution, with native RAID (0, 1, 1+0) support.

    You can install a SSD directly to the card via a convenient metal latching clip to help relieve the internal space constraints often associated with multiple hard drive configurations. Plus the controller card also includes a low profile/half-height installation bracket for small form factor (SFF) systems.
