Why Disk Space Matters
Disk space refers to the total amount of data a storage drive can hold, measured in gigabytes (GB) or terabytes (TB). Operating systems, heavy software applications, games, and personal media files quickly consume this capacity. Running out of disk space doesn't just limit your storage—it drastically slows down system performance because your OS lacks the room required for temporary virtual memory (swap space).
