4. Reasons for the growth of data

Capacity- Since capacity of hard drives and storage media is increasing, the cost of storage capacity is decreasing, roughly, the capacity doubles each year under "Kryder's Law"

Security - So many businesses use CCTV to capture video and audio footage for security purposes, which can take up large amounts of storage space after a while. System logs are also kept by many businesses which must also be stored.

Other devices - Data collected from other devices within a person or company's space such as scanners, sensors, etc, will also need to have their data stored

Social data - It is increasingly common now for businesses to collect personal data to aid things such as third party advertising for tailoring ads to users

Regulations - Regulations are constantly changing, requiring companies to keep more and more data and changing what data must be retained by the organisation

Cloud Storage - Cloud increases with popularity with each passing day and this keeps keeps the capital cost of big data low. It also allows for on demand expansion/increases in capacity and data size
