After all other hard drives were already converted to USB 3, was missing the connection for Seagate. Now the system is perfect, and the effort was worth it. Forget the sad times, when there was no USB 3. Compared to charge a USB 2 drives the part needs only about one-fifth of the time. A normal film is dubbed in 2 to 3 minutes, at an AVI movie you need not even look at the clock. Am fully satisfied and can only recommend the part of all users Seagate highly.
