How is OCI File Storage priced?

OCI File Storage charges for consumed capacity — you pay only for the data you store, not provisioned capacity. Pricing is per GB per month for file system data, with additional charges for snapshots (only changed blocks are billed). Mount targets have a small hourly charge. There are no charges for IOPS or throughput — performance scales automatically with file system size. This pay-per-use model makes File Storage cost-effective for workloads with variable storage needs.

What performance can I expect from OCI File Storage?

File Storage performance scales with the size of the file system. A 1 TB file system provides approximately 60 MB/s throughput and 8,000 IOPS. As the file system grows, throughput and IOPS increase proportionally. For workloads needing higher performance at smaller sizes, consider using Block Volumes with multi-attach or a higher-performance storage tier. File Storage is ideal for shared access patterns where multiple instances need concurrent read/write access.

See It in Action

Your team's CI/CD pipeline shares build artifacts across 50 build agents via a self-managed NFS server on OCI Compute (~$200/month for the VM + $300/month for block storage). The builder shows OCI File Storage equivalent: ~$0.10/GB-month × 2 TB = $200/month for the same shared file system, plus elimination of the NFS server VM. Net savings: $300/month. Plus the operational simplification of no NFS server to maintain (patching, monitoring, scaling).

What This Tool Does

OCI File Storage provides managed NFS file systems that can be mounted by Compute instances, container workloads, and on-premises clients. Pricing is based on consumed storage capacity (not provisioned), with no minimum commitment. File Storage supports snapshots, clones, and cross-AD replication for data protection. This estimator calculates monthly costs based on your expected storage consumption, snapshot usage, replication needs, and mount target configurations.

Technical Details

The estimator computes OCI File Storage monthly cost as: stored capacity × per-GB-month rate, plus snapshot data (changed blocks only) × per-GB-month rate, plus cross-AD replication multiplier (×2 cost when enabled), plus mount target hourly fee. Output presents per-component breakdown plus comparison against equivalent Block Volume cost (for cases where shared access isn't needed).

Common Use Cases

1Estimating monthly costs for a shared NFS file system used by a fleet of Compute instances for application data and configuration files
2Calculating the cost impact of snapshot retention policies that keep daily snapshots for 30 days and weekly snapshots for 90 days
3Budgeting for File Storage replication to a secondary availability domain for disaster recovery of critical shared file data
4Comparing OCI File Storage costs against Block Volume costs for workloads that could use either shared or instance-attached storage

Expert Tips

TIP

OCI File Storage's pay-per-consumed-capacity model is genuinely simpler than AWS EFS or Azure Files. No upfront provisioning, no IOPS provisioning, no 'burst credits' to worry about. You write data → you pay for it. The pricing simplicity is itself a feature for cost predictability.

TIP

Snapshots only bill for changed blocks. A 1 TB file system with a snapshot of unchanged data costs near-zero for the snapshot. Daily snapshots with 30-day retention typically add 10-30% to storage cost depending on data churn rate — much cheaper than alternatives requiring full snapshot copies.

TIP

Cross-AD replication doubles per-GB cost (you're billed in both ADs) but provides zone-level DR. For non-critical workloads, scheduled exports to Object Storage Coldline tier are dramatically cheaper than always-on replication while still meeting RPO requirements.
