Now the negative and the reason why I have returned there after 5 Days: USB 3.0 does not work properly. When it is testing fast times, one is surprised by the speed and very satisfied. 90 to 100 MB / sec go easy there. But after 20 or 90GB hard drive is not recognized Mher and the transfer is aborted. Since then helps only Fetsplatte to unplug and plug restart. Then they will unhesitatingly recognized again until you re-try larger amounts of data via USB to transfer 3.0. Have connected via PCI card (8x) a Asmedia. With countless drivers constellations aktuelleste attempts recommended / certified. Always with the same result: the data transfer from bircht with the error message "File can not be found". This then is also true because the entire drive is no longer recognized. Tested with 2 different hard drives. In contrast, USB 2.0 was not difficult.
Anyway, after more than 1 year USB 3.0, I expect that it should make no coarser mittlwerweile problems when you bring together a hard disk controller and a USB controller. Therefore, the panel had as good it was (from the outside), back. According to Google, and after thinning various forums I was not the only one with my problem by far. It only remains for me the question which HDD enclosure should I buy now.
