How do hard drives work?

Whether you’re a hardworking professional, a photography enthusiast, or a current college student, a great hard drive can solve all your storage needs. A hard drive (sometimes called a hard disk drive) stores all kinds of digital content, either inside your computer or as a separate device.

Hard drives inside your computer typically use an interface called SATA to access and store data within your device. External hard drives connect to your computer using some kind of cable, such as a USB 3.0 cord. Both internal and external hard drives can be compatible with Mac computers or PCs.
