Built in four SATA 3.0 (6gbps) interfaces, supporting high-capacity hard disk and SSD; It supports hot swap of SATA interface, and wiring port is set behind, so it will not with graphics card. Using four layer circuit board, adding isolation layer in middle, the anti-interference ability is stronger, the tail edge design, reduce probability of blocking video card fan. With larger heat sink, the heat dissipation effect is better, and product runs more stably, which is suitable for long-time work. Adopt heavy gold technology to thicken golden finger, better contact, high speed, strong reliability, PCIE X1 interface, PClE interface can be used. Interface: SATA3.0x4 Type:PCIE to SATA3.0 Expansion Card Name:SATA Riser Card Colour: black + green Material: PCB Package Contents: 2 * Expanding Board Only above package content, other products are not included. Note: Light and different displays may cause color of item in picture a little different from real thing. The measurement allowed error is +/- 1-3cm.
