The hard drive depends on me at the TV. It is small (hidden behind the screen), very quietly and quickly. She does not need external power and no Y-cable. At night I put on my device from the mains and when I turn on the TV the next day, he is about to start with his ongoing recording. The board can not long in coming and soon the television in standby enter, they will cease to rotate. After a few seconds even the lights go out. For this purpose, it is in any case more suitable.
