Most off-the-shelf usB3.0 cards implement mulple ports with a single USB3.0 controller which results in significant performance degrada on during mul-port opera on. To achieve maximum per-port performance, it has four independent Nec upD720202 USB3.0 Host Controllers and x4 PCl ExpressGen2interface to offer up to 5 Gbps bandwidth for each port,independently. in addi on to transfer data bandwidth advantage,it features on-board regulated 5v Dc power supply with a unique configurable 900mA1500mA current limit to supply stable 5V DC power to external usB devices. lt also supports software-programmable per-port power on/off control for fault recovery opera ons.
Combining high bandwidth, industrial-grade power design and reliable cable connec on, it brings convenience to interface USB30 devices opera ng under Windows XP, 7, 8, 10 and Linux.
