Built in four SATA 3.0 (6gbps) interfaces, supporting high-capacity hard disk and SSD; It supports hot swap of SATA interface, and the wiring port is set behind, so it will not with the graphics card. Using four layer circuit board, adding isolation layer in the middle, the anti-interference ability is stronger, the tail edge design, reduce the probability of blocking the video card fan. With larger heat sink, the heat dissipation effect is better, and the product runs more stably, which is suitable for long-time work. Adopt heavy gold technology to thicken the golden finger, better contact, high speed, strong reliability, PCIE X1 interface, PClE interface can be used.
