Features

​

Storage class

• Single class today: NVMe SSD — every bucket is backed by NVMe SSDs, tuned for high-performance access (low latency, high IOPS, parallel reads/writes)
• HDD class coming — a cost-effective tier for cold or archival workloads is on the roadmap; pricing and SDK semantics will land here when it ships

​

S3 compatibility

• Endpoint: https://<bucket-name>.s3.raffusercloud.com (virtual-hosted style)
• Signature version: AWS SigV4
• SDK support: any AWS S3 SDK — boto3 (Python), AWS SDK for Go / Java / JavaScript / .NET, the aws-cli, and tools like mc / rclone / s3cmd / Cyberduck
• See S3 compatibility for the full feature matrix

​

Bucket and object operations

• Bucket CRUD, list, ACL (private / public-read)
• Object PUT / GET / DELETE / HEAD
• Multipart upload (automatic for files ≥ 10 MB via dashboard)
• Presigned URLs (SigV4)
• CORS configuration
• Custom metadata on objects

​

Encryption

• Encryption at rest — enabled by default at the platform level

​

Bandwidth

• Free between Raff VMs / Kubernetes and Object Storage in the same region (private network)
• Inbound (uploads) is free, never metered
• Public internet egress — first 1 TB / month free, then $0.01/GB (measured by the Ceph RGW usage API and settled month-end)

​

Pricing

Object Storage uses the same dual-mode billing as VMs and volumes: subscription by default, PAYG on request — both at the same effective per-GB rate.

​

Subscription (default)

A starter package covers most workloads: The first $7/month covers up to 100 GB across all your buckets in the account. As your usage grows past 100 GB, the additional storage is billed at $0.07/GB/month, accruing continuously and settled month-end on the 1st against your account balance.

​

Pay-as-you-go (enterprise / SMB on request)

PAYG is available for enterprise and SMB customers — contact support to enable. PAYG has no monthly minimum — you only pay for what you store, billed at the same per-GB rate as the subscription overage.

​

Subscription vs PAYG

If you reliably store 100+ GB, subscription is cheaper (the first 100 GB costs $7 instead of $7/month at the PAYG per-GB rate, which works out the same — but subscription locks the price). If you store much less than 100 GB on average, PAYG is cheaper (you skip the flat $7). For the wider money flow (balance, cards, credit-on-delete, billing date rotation), see Billing model.

​

Limits

The dashboard upload dialog says “Large files (100 MB+) use multipart upload automatically” — that’s a simplification. The actual switch happens at 10 MB. Anything above that is multipart; anything below is a single signed PUT. For SDK access (boto3, aws-cli, etc.), the standard S3 multipart limits apply — minimum 5 MiB per part except the last, maximum 5 GiB per part, up to 10,000 parts per upload.

​

Bandwidth

The first 1 TB of public-internet egress per month is included free. Beyond 1 TB, egress is billed at $0.01/GB and measured by the Ceph RGW usage API. Inbound and same-region private traffic (between Raff VMs / Kubernetes and Object Storage) are always free. For most workloads — application backups, ML artifacts, internal data lakes — same-region traffic dominates and the public-egress meter never moves. Public-bucket workloads (static sites, CDN origins, asset distribution) consume the 1 TB free tier first, then start paying $0.01/GB. At Raff’s rate, that’s a fraction of major-cloud egress charges; budget for it on heavy public traffic. Egress accrues continuously and settles month-end on the 1st against your account balance, the same way storage does.
