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
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.
Egress	Free and anonymous. 'Anonymous downloads are enabled' over FTP; also HTTPS. No egress meter anywhere in the docs.
Identity	anonymous derived from the record's prose, not from an identity field, and no signup was executed: ount; each accession gets its own directory tree. Read side anonymous per-file HTTP, so it fronts to a CDN trivially. per-object-cap: none stated; Aspera recommended above 10 GiB. Binding c

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.
Binding	per-ip-shaping one stream is shaped, and a user's throughput is the shaped rate times the number of streams
Interface	ftp, nfs ftp
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.
Notes	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.

Sibling records disagree:

verdict: storage/ena says fails-quota, storage/ena-webin says qualifies
identity_kind: storage/ena says email, storage/ena-webin says anonymous

Free tier	No fixed quota. Own fair-use policy: 'We place no absolute limit within the 2-month period on the total volume of user data that may exist in a data upload area at any one time' and 'we ... expect that volumes would not exceed 10 Terabytes under normal circumstances.' unit mixed; metered on unstated
Price	none stated
Per-object cap	not stated
Retention	Retention: transit area purged after 2 months if not submitted; once submitted, ENA is permanent (60 days)
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.
Identity	anonymous derived from the record's prose, not from an identity field, and no signup was executed: ead 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. per-object-cap: none documente
Limits	per-ip-shaping 45 KB/s source per-ip-shaping 430 KB/s source retention-clamped Retention: transit area purged after 2 months source 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).
Binding	retention-clamped a clock, not a quota: bytes leave whether or not the client is finished with them
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'.
Notes	No fixed quota. Own fair-use policy: 'We place no absolute limit within the 2-month period on the total volume of user data that may exist in a data upload area at any one time' and 'we ... expect that volumes would not exceed 10 Terabytes under normal circumstances.'
