(Even with 8 USB ports it's still one controller.) tests show otherwise: single usb stick: Results: 967 seeks/second, 1.03 ms random access time 3 usb sticks on a hub accessed concurrently: Results: 907 seeks/second, 1.10 ms random access time Results: 916 seeks/second, 1.09 ms random access time Results: 915 seeks/second, 1.09 ms random access time _______________________________________________ A51 mailing list [email protected] http://lists.lists.reflextor.com/cgi-bin/mailman/listinfo/a51
