$7 / month flat (included in the base subscription)
Above 100 GB
$0.07 / GB / month (pro-rated)
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.
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.
10 MB — files at or above this size automatically use multipart upload
Default multipart part size (dashboard)
16 MB (AWS SDK v3 default)
Max parts per multipart upload
10,000 (Ceph RGW / S3 standard)
Max object size
5 TiB (Ceph RGW limit)
Max upload via dashboard
Up to 5 TiB in theory — the dashboard auto-scales chunk size as fileSize / 10000 to stay under the 10,000-part cap; practical browser memory limits will hit before this
Max single PUT (under the multipart threshold)
~10 MB — anything larger is automatically chunked
Concurrent file uploads (dashboard)
3 files at a time
Concurrent chunks per file (dashboard)
10 in parallel
Buckets per account
No hard cap published; subject to overall account capacity
Bucket name length
3 - 54 characters (lowercase letters / digits / - / .; must start and end with a letter or digit; globally unique across all Raff accounts)
Region scope
Each bucket lives in one region — us-east is the only region today
Access keys
Two scopes: Full Access (every bucket) or Limited (specific buckets via auto-generated bucket policy) — see Generate access keys
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.
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.
