Hard Disk Drives: Long-Term Storage
The hard disk drive inside your computer stores all your important data—up to 1 terabyte (TB) or more, depending on your computer. A hard disk consists of metallic platters that store data magnetically. Special read/write heads realign magnetic particles on the platters, much like a recording head records data onto magnetic recording tape.
