(5 stars) Great product for extra data storage!

I'm using two of these connected to ASMedia SATA ports, yielding EIGHT extra ports... (Note that Intel ports do not support multiplication.) The small size of the card allows for improvisation re location inside the case, thereby NOT necessarily necessitating taking up an expansion slot. No drivers necessary - works great in Linux! ... Use ports in proper order (A,B,C,D) if using less than all four ports. No discernible read-write difference on drives connected with this card. Very happy using same and highly recommend!
