As a loyal CUSTOMER, I was excited to try this mini SAS controller for my computers .However, as my tests showed, the performance was quite disappointing. The worst part was the poor quality cables that came with the controller. They were flimsy and fragile, making it difficult to obtain a reliable transfer rate. The pros of this device are its compact size and ease of installation, but these advantages are overshadowed by its subpar performance and low-quality cables..
