It depends on the model and size of your hard drive. Most modern hard drives are designed to hold a considerable amount of data, but the exact amount of data that your hard drive can handle without running into trouble depends on its model and capacity. You can check the manufacturer’s specifications for your hard drive to find out more about its capacity and how much data it can store. If you are running out of storage space, you may need to upgrade your hard drive or purchase an external hard drive for additional storage.
