Anatomy of Hard Disk Drives – A Deep Look into Hard Drives
Posted on August 21, 2008. Filed under: Hardware Tangents |
Prior to actually getting into which hard disks are the best technology to pursue, I am going to explain the different parts of the hard disk. This is essential when getting into the configuration of the disks to understand how the disks work. This is really simple stuff!

Shown above is the basic architecture of a hard disk drive. There are tracks, sectors and heads:
Tracks can be thought of as guides for where the data should be placed on the hard drive.
Sectors are logical segments or groups where the 1s and 0s are stored. This allows the disk head to SKIP over data that it doesn’t need to read.
The Head is what reads the data (1s and 0s) from each sector.
