hard drive

Computer's permanent memory

A hard drive is a computer storage device that holds data magnetically on spinning metal disks.

The term persists even as solid-state drives (SSDs) have largely replaced the older technology: My hard drive crashed and I lost everything.

Often shortened to drive or HD.
