Q: What's the difference between OtterPool and OtterVault?

OtterPool is standard general-purpose storage. OtterVault is critical storage: it ships with versioning and immutability (Object Lock in Compliance mode) to protect data against deletes and ransomware during the retention period.

Q: When should I choose OtterArchive or OtterLake?

OtterArchive is for infrequently accessed historical data at the lowest cost (HDD + lifecycle to cold). OtterLake is for large volumes and AI/dataset workloads that need maximum performance (NVMe/SSD).

They all speak S3 and use the same buckets under the hood. What changes is what you expect from each: disk technology, immutability, versioning, and cost. Choose the one that fits your data.

Comparison

Technical features, side by side.

All four storage services are S3 bucket types: the difference is the recommended configuration and the disk technology.

Price depends on the disk technology chosen per bucket (HDD €8 · SSD €16 · NVMe €45 per TB and month), not on the service itself. Object Lock can only be enabled when the bucket is created. Requests and deletes are never billed. See the full pricing.

Questions to help you choose.

Can I choose the disk technology? +

Yes. Each bucket is created with HDD, SSD, or NVMe based on the service and the zone. It's the factor that determines performance and price; it can't be changed after the bucket is created.

OtterPool is standard general-purpose storage. OtterVault is critical storage: it ships with versioning and immutability (Object Lock in Compliance mode) to protect data against deletes and ransomware during the retention period.

When should I choose OtterArchive or OtterLake? +

OtterArchive is for infrequently accessed historical data at the lowest cost (HDD + lifecycle to cold). OtterLake is for large volumes and AI/dataset workloads that need maximum performance (NVMe/SSD).

Can I switch services later? +

All services are standard S3 buckets, so you can adjust versioning, lifecycle, or policies whenever you want. Immutability (Object Lock) and disk technology are fixed when the bucket is created; to change them, create a new bucket and migrate the objects with OtterBridge.
