Excellent product we have here! Rack for HDD / SSD SATA that fits into a slot for portable optical drive (CD / DVD / BLURAY) and USB2 in Boitie to keep your optical drive in working! For my part, it has a BLU RAY player and works beautifully even USB2. As for the HDD rack, it allows me to add a third hard drive or SSD in my laptop. And to make things right, we keep the front of the laptop disk drive to put it back on the rack. Neither seen nor known! Product totally satisfactory for a small price!
