I tested this at two computers with very different hardware. The result was exactly the same. Also I tested with three different USB devices. 1st USB HDD ( ~ 25 MB/s ) 2nd microSD card in a Garmin GPS device ( ~ 1.7 MB/s ) 3rd compact flash card in a camera ( ~ 0.8 MB/s ) For the following tests I used the slowest device. At first I copied data by using of Dolphin and did measure time until desktop freezing. 1st test: 12 minutes 27 seconds 2nd test: 12 minutes 17 seconds 3rd test: 12 minutes 23 seconds Then I did this test once again by using of Konqueror. 1st test: 12 minutes 00 seconds After freezing of desktop sometimes session will terminated automaticly and switched back to login screen. Always it is possible to switch to a text console and to shut down computer. Once I got a kernelpanic error message during shut down.
