The cable is capable SATA6, is perfectly suited for the installation of a SSD in the upper space. Was delivered very quickly !! After I had ordered 2 cable previously (from another dealer), both of which were not capable SATA6, I was careful and did this dealer (Mac Speicherschop) beforehand contacted and demand. Competent consulting! Thank you, gladly again! My Mac mini now runs with 2 SSDs :)
