Frequently Asked Questions
How accurate is this EFS pricing calculator?
This EFS pricing calculator uses official AWS pricing data updated regularly from Amazon's public pricing API. It accounts for regional pricing differences, and Elastic Throughput data access charges. For production budgets, verify final costs in the AWS Billing console since pricing occasionally changes.
Should I use Regional or One Zone file systems?
Regional (Multi-AZ) is recommended for production workloads. It provides highest availability by replicating data across multiple Availability Zones. One Zone file systems are ~47% cheaper but store data in a single AZ - use them for development, testing, or workloads that don't require Multi-AZ resilience.
What is Elastic Throughput mode?
Elastic Throughput is the default and recommended throughput mode for EFS. Performance automatically scales with your workload activity - you pay only for the data you read and write (per GB transferred). This is ideal for spiky or unpredictable workloads where you don't want to provision throughput in advance.
What are the EFS storage classes?
EFS offers three storage classes: Standard for frequently accessed data with sub-millisecond latency, Infrequent Access (IA) for data accessed a few times per quarter with lower storage costs but higher access charges, and Archive for data accessed a few times per year or less with the lowest storage cost. Enable Intelligent-Tiering to automatically move files between classes.
Why do IA and Archive have additional access charges?
IA and Archive storage classes have significantly lower storage costs (up to 95% cheaper for Archive) but charge additional per-GB fees when you access data. Standard storage includes access in the storage price. Choose IA/Archive for data you rarely access - the lower storage costs outweigh access charges for infrequent reads.
