StarTech.com PCI Express 2.0 SATA III 6Gbps Mini-SAS (SFF-8087) RAID Controller Card w/ HyperDuo SSD Tiering - PCIe SATA 6Gb RAID Card
Add Internal SATA III (6Gbps) support to a computer through a single Mini SAS (SFF-8087) port - The PEXSAT34SFF PCI Express 2.0 SATA Controller Card enables 4 AHCI SATA III connections to be added to a computer through a single internal Mini-SAS (SFF-8087) port. The Mini-SAS connector with Port Multiplier support allows for multiple SATA drives (up to 7) to be connected using a single cable. When used with our Mini-SAS to 4x SATA breakout cable  or Mini-SAS SFF-8087 backplane (accessories not included, SAS drives not supported), you have a complete internal 6Gbps connectivity solution, all from a single card. 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). Compliant with SATA revision 3.0, this PCI Express SATA RAID card delivers up to 6Gbps of data bandwidth; ideal for high performance hard drives and solid state drives (SSD). Plus, the controller card offers an effective hardware RAID solution, with native RAID (0, 1, 1+0) support.Throughput Benchmark Drive configuration, Throughput, Drive size. 1 x HDD, 112.81 MB/s, 2 TB. 1 x SSD, 490.28 MB/S, 120 GB. 1 x HDD + 1 x SSD HyperDuo (Safe Mode), 489.28 MB/s,2 TB. 1 x HDD + 2 x SSD HyperDuo (Safe Mode), 715.13 MB/s, 2 TB.
