Disk Drive Basics

The performance of an HDD is affected by its RPM (rotations per minute) of the drive platter. A higher RPM generally results in faster read/write performance.

A hard disk drive (HDD) is a non-volatile, digital data storage device that records data magnetically onto the hard disk. It stores data by using read/write heads that roll across concentric circles called tracks on the disk.

HDDs contain moving parts, which makes them vulnerable to physical damage.

<p>Tracks on a hard disk are organized as concentric circles on the platters, with each platter having two surfaces. Read/write is performed by rolling headers from the inner to the outermost part of the disk.</p> Signup and view all the answers
