I received the product very well, it happened quickly and new. I just have a little disappointment. I wanted to use this adapter to take full advantage of the power of my case Icy Box containing two hard drives. But unfortunately the connection of it, mark it as a single hard drive, either Linux or Windows. BTW, this cable works great for Linux, you can expect a transfer of 80 mb / s with hard drives of 7200 rev / min. If someone would be why it does mark a hard drive as the conduct to be me I would be very grateful.
