StarTech.com PEXMSATA3422 - 2-Port PCIe 2.0 SATA III 6Gbp/s RAID Card with 2 MSATA Slots & HyperDuo SSD Tiering

Combine SSD performance with HDD capacity to create a HyperDuo array with 2 x mSATA and 2 x SATA drives through a single PCI Express slot. The PEXMSATA3422 PCI Express SATA Card helps you improve the overall speed and storage capacity of your computer by giving you multiple 6 Gbps SATA connections for connecting high-performance SSDs (Solid State Drives) and hard drives in a HyperDuo array. Now you can easily add two mSATA slots and two SATA III ports to your computer through a single PCIe x4 slot.

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 computers that use a BIOS.)

This versatile RAID controller card helps to relieve the internal space constraints often associated with multi-drive configurations by letting you install two mSATA SSDs directly to the card via convenient latching slots. With dual mSATA slots as well as two internal SATA ports the card offers an effective hardware RAID solution with native RAID (0 1) support.

The PCIe SATA controller also offers Port Multiplier (PM) support so you can connect multiple SATA drives to just one port for a total of 7 drives (up to 4 drives through PM on one port plus a single drive to the other SATA port and two mSATA slots).

For added versatility the controller card is equipped with a standard profile bracket and includes a low-profile/half- height bracket for installation in small form-factor computers.
