Exabyte Storage Cost: Cloud Storage vs. Spacetime
Exabyte Storage Cost: Cloud Storage vs. Spacetime
When data reaches the exabyte range, you are not really a cloud customer anymore. You are the cloud provider and storage cost becomes less about capacity and more about predictability.
Cloud platforms often look affordable on paper, a few euros per terabyte per month. But at exabyte scale, the real cost includes constant retrievals, metadata operations, background processes, region transfers, and occasional egress events. These add up quickly.
It’s hard to give a definitive cost for storing an exabyte in a standard cloud tier. We estimate it starts above €6 million per month but that figure can easily reach €50–€100 million, depending on storage class, region, and activity levels. Archive tiers may reduce the baseline but introduce retrieval fees that can easily spike costs during audits, reprocessing, or model retraining.
For many large organizations, the biggest problem isn’t the baseline price, it’s that the total bill never looks the same twice.
SpaceTime approach is different
Our storage model is built specifically for massive, long-term archives that rarely change. Instead of tying your monthly invoice to how often your teams touch the data, we offer one predictable, fixed price for exabyte-scale storage inside Finnish bedrock. No retrieval charges. No API costs. No egress surprises. Just stable, deterministic storage economics.
For large datasets that are primarily cold (everything from scientific archives and satellite imagery to compliance repositories, ML training datasets, and long-retention backups) the difference is significant. Cloud pricing follows activity. SpaceTime pricing follows capacity. This makes long-term planning dramatically simpler.
And because our model removes the activity-based billing that inflates cloud costs, typical exabyte storage with SpaceTime is 20–30% lower than equivalent cloud storage. In many cases, the difference is even larger when usage patterns fluctuate heavily throughout the year.
If your organization is evaluating exabyte-level storage, or if cloud unpredictability is starting to affect your budget planning, we can calculate your exact long-term cost with SpaceTime, clearly and without hidden add-ons.
