Key features

• •Up to Six SATA III Ports: Thanks to the built-in support for SATA Port Multipliers with FIS-based switching or Command Based switching, allowing you to easily connect six additional HDD/SSD drives. And, the SATA ports are bootable.
• •High Speed: The SATA III ports deliver a blistering fast data transfer speed of up to 6Gbps, letting you transfer monstrous amounts of data in seconds. They are also backward compatible with SATA I (1.5Gbps) and II (3Gbps) standards.
• •NCQ Support: Native Command Queue allowing hard disk drives to internally optimize the order in which received read and write commands are executed. This can reduce the amount of unnecessary drive head movement, resulting in increased performance.
• •Hot Swapability: This card supports hot plug and hot swap functions. Simply plug it into your computer system, and it's ready to work.
• •Great Compatibility: PCI-E controller card is compliant with PCI-E specification V2.0, and backwards compatible with PCI-E 1.0. For added flexibility, it's also compatible with PCI-E x2, x4, x8 and x16 slots, and with the included low-profile bracket.
• •Extra large heat sink for better heat dissipation.
• •The rear six-port design makes wiring more convenient.
• •Rear six-port design, universal for small or large size chassis.
• •The tail is designed to be close to the edge, small chance of blocking the fan of the graphics card.
• •Four-layer circuit board with isolation layer in the middle for stronger anti-interference ability.
• •Under the PCI-E 2.0 version, the single port speed can reach 520 Mbps or so.
• •Support SATA Hot Plug for both of host port and device ports
• •Support SATA NCQ command
• •Support over 2TB drives
• •Support SATA Partial/Slumber
