Скорость чтения внешних HDD (с питанием по USB) дико низкая, скорость записи же нормальная.
Проверял 3 разных HDD (с питанием по USB), все USB2.0 и у всех результат теста приблизительно одинаков.
В Windows, все HDD работают нормально.
Тот HDD что с теста на 250GB, жрет 451mA (+5V)
по стандарту USB2.0 выдает 500mA, а USB3.0 900mA
однако скорость чтения HDD, практически не отличается на двух портах
в dmesg есть кое-какие ошибки, что бы они могли значить? Недостаточно питания? Как решить данную проблему?
