StarTech.com 4 Port PCI Express 2.0 SATA III 6Gbps RAID Controller Card with HyperDuo SSD Tiering - PCIe SATA 3 Controller Adapter , TAA (PEXSAT34RH)

The PEXSAT34RH 4-Port PCI Express 2.0 SATA Controller Card with HyperDuo adds four AHCI SATA III ports to a computer through a PCIe slot (x2), delivering multiple internal 6Gbps connections for high-performance hard drives and Solid State Drives (SSDs). 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 supports Port Multiplier (PM), enabling multiple SATA drives to be connected to one port over a single cable, for a total of seven drives (up to four drives through PM on one port, and a single drive to the remaining three ports). Plus, the SATA controller card offers an effective hardware RAID solution, with native RAID (0, 1, 1+0) support.
