How many hours of tv can you record on one terabyte hard drive?

The amount of TV you can record on a one terabyte (TB) hard drive depends on the quality and resolution of the recording. For standard definition (SD) content, you can typically store around 250-300 hours of TV. For high definition (HD) content, this drops to roughly 100-150 hours. Ultra HD (4K) recordings significantly reduce that capacity further, often allowing only about 20-30 hours of content.
