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.

Track numbering on a hard disk begins at 0 from the outer edge and moves towards the center.

HDDs can be differentiated based on measurements such as capacity, access time, and transfer time.

The characteristics of an HDD include non-volatile digital data storage, magnetic data recording, RPM-dependent read/write performance, and susceptibility to physical damage due to moving parts.

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.

The numbering system for tracks on a hard disk starts at 0 from the outer edge and progresses towards the center.

The factors affecting the performance of an HDD include capacity, access time, and transfer time.

HDDs are susceptible to physical damage because they contain moving parts that can be easily affected by external forces.
