Tape represents the most cost-efficient medium for archival records retention, backups, and disaster recovery thanks to a long lifespan and low media cost per TB.
Cloud Storage Costs
Cloud storage delivers flexible, scalable capacity without large hardware investments. Leading cloud providers like Amazon AWS, Microsoft Azure, and Google Cloud Platform rent storage for monthly fees based on provisioned capacity and access frequency. 1TB of cloud storage ranges from $10 to $50 per month on average. Key variables include:
- Public vs private cloud – Private clouds and dedicated hardware are more expensive.
- Access frequency – Frequently accessed “hot” storage costs more than archival “cold” storage.
- Availability and durability – Higher levels of redundancy and backups add costs.
- Data transfer fees – Moving data in and out of cloud storage incurs additional fees.
- Location of data center – Storage costs vary across geographic data center regions.
- Premium features – Advanced security, compliance controls, and management tools increase costs.
With easy scaling and no hardware investment, cloud storage allows consumption on-demand at a reasonable monthly cost, averaging $10 to $50 per TB.
