There is not much to say. It met for the purpose and the very very good. They want it hard but believe I get the same transmission rate by the stroke drawn off as directly to the PC. My ultimate test is an external SSD to the 300Mb / s write and 350MB / s read throughput has. That I get directly to the PC via USB 3.0 out exactly as per SATA port The great thing is that the transmission rate remains the same no matter directly to the PC or hub. Even if I make a backup on another disk. The Hub is a real buy recommendation
