Data Density

Data density represents the amount of information that can be stored within a defined space or medium, serving as a crucial metric in both physical and digital storage systems. This concept has become increasingly important as our need to store and process vast amounts of information continues to grow.

Physical Manifestations

Storage Media

Physical data density is measured in various ways depending on the medium:

• Magnetic storage: bits per square inch
• Optical discs: gigabytes per layer
• Solid-state storage: cells per unit area

The evolution of storage technologies has led to remarkable improvements in data compression techniques and physical storage capabilities.

Digital Considerations
