| Free tier | Free deposit, no published cap. 'Is there a cost to deposit data in BioStudies? No, both deposition of data to BioStudies and data access are free of charge.' Docs discuss 'larger data volumes (hundreds of GiB)' as routine. unit unlimited; metered on unstated |
|---|---|
| Price | none stated |
| Limits | per-object-cap: none stated; Aspera recommended above 10 GiB. Binding constraint on read is per-ip-shaping — 1 stream 7 KB/s, 16 parallel 25 KB/s against the EBI FTP edge. Retention: permanent, DOI auto-assigned; files can sit 'hold until published' indefinitely before release. |
| Identity | email depositing needs a BioStudies submission-tool account, created with a name, an email address and a password; the ORCID field is optional. No card and no phone number is asked for. Reading published data needs no account at all. |
| Egress | Free and anonymous. 'Anonymous downloads are enabled' over FTP; also HTTPS. No egress meter anywhere in the docs. |
| Per-object cap | not stated |
| Retention | Binding constraint on read is per-ip-shaping — 1 stream 7 KB/s, 16 parallel 25 KB/s against the EBI FTP edge. Retention: permanent, DOI auto-assigned; files can sit 'hold until published' indefinitely before release. |
| Interface | ftp, nfs part of the text of Limits, above |
| Tooling | Submission Tool + FTP + Aspera (ascp) in; anonymous FTP/HTTPS out. Path is predictable: /biostudies/<mode>/<COLL>/<COLL0-99>/<ACC>/Files/ where mode is fire or nfs. |
| Composes with | ArrayExpress is a BioStudies collection, so one account covers both. Unlimited accessions per account; each accession gets its own directory tree. Read side anonymous per-file HTTP, so it fronts to a CDN trivially. |
| Reliability | Read edge is slow per connection and stalls connections under parallel load (one of 16 timed out with 0 bytes). Fetches from the same EBI edge as ENA/PRIDE, so they are one throughput pool, not three. |

per-object-cap: none documented per file; per-request volume soft-capped at ~10 TB per 2-month window per upload area, and upload areas are not backed up. Retention: transit area purged after 2 months if not submitted; once submitted, ENA is permanent. Binding constraint on READ is per-ip-shaping: single stream 45 KB/s, 8 parallel ranged GETs 430 KB/s (9.6x). |
| Identity | anonymous (inferred, not read) not published |
| Egress | Unmetered and anonymous. ftp.sra.ebi.ac.uk is CORS-open (Access-Control-Allow-Origin: *) and already served through Cloudflare (Server: cloudflare), so CF is in front by default. |
| Per-object cap | not stated |
| Retention | Retention: transit area purged after 2 months if not submitted; once submitted, ENA is permanent (60 days) |
| Interface | sftp, ftp, rclone, cli sftp |
| Tooling | Webin-CLI (github.com/enasequence/webin-cli), plus plain FTP/Aspera. Read side is plain HTTPS/FTP with HTTP range support — works with rclone's http/sftp remotes and curl. |
| Composes with | One Webin account = unlimited studies. The upload area is a transit buffer (10 TB documented expectation), while published accessions are permanent and unmetered on the read side. Multiply across accounts/centres; read side needs no account at all, so the fetch workload is uncapped regardless of how many deposit accounts exist. |
| Reliability | Upload path is the weak side — FTP sessions drop out, Aspera recommended; upload area is explicitly 'not backed up'. |
