What are the key differences between Filestore tiers?

Basic HDD offers the lowest cost per GB but limited IOPS (600 read, 1000 write). Basic SSD provides higher performance (60K read IOPS) at moderate cost. Zonal tier offers flexible capacity scaling in 256 GiB increments with high performance. Regional tier adds synchronous replication across zones. Enterprise tier provides the highest availability with regional replication, snapshots, and up to 120K IOPS. Choose based on your performance, availability, and budget requirements.

How is Filestore priced differently from Cloud Storage?

Filestore charges per GiB of provisioned capacity per month regardless of how much data you store — you pay for the full provisioned size. Cloud Storage charges per GiB of data actually stored plus per-operation fees. Filestore is cost-effective when you need consistent NFS performance and will utilize most of the provisioned capacity; Cloud Storage is cheaper for variable or object-based workloads.

About This Tool

Filestore provides fully managed NFS file servers for GKE workloads, Compute Engine instances, and on-premises clients that need shared POSIX-compliant storage. Costs depend on the service tier (Basic HDD, Basic SSD, Zonal, Regional, Enterprise), provisioned capacity, and region. Higher tiers offer better IOPS and throughput but at increased cost. This estimator calculates monthly expenses based on your tier selection, capacity requirements, and region, helping you compare tiers and right-size your Filestore instances.

When to Use This Tool

•Comparing monthly costs between Basic SSD and Enterprise tiers for a media rendering pipeline that needs high IOPS shared storage
•Estimating storage costs for a GKE cluster that needs ReadWriteMany persistent volumes backed by Filestore
•Budgeting for Filestore Enterprise instances that provide regional availability for mission-critical NFS workloads
•Evaluating whether Filestore Zonal or Cloud Storage FUSE is more cost-effective for batch processing workloads
