Free tier	50 GB and 100 files per record by default; 10 GB per file. Quota increase is granted on email request to researchdata@kth.se. Not a hard wall — a record with a 70.4 GB single object exists in the public API, i.e. increases are real and granted. unit objects; metered on unstated
Price	none stated
Per-object cap	10 GB per file (10000000000 bytes)
Retention	not stated
Egress	Free and anonymous. Downloads 302 to presigned.s3.cloud.kth.se with X-Amz-Expires=60 — sixty seconds, so rule 8 applies hard: re-resolve per request or watch every parallel GET return an empty 302.
Identity	institution institution
Limits	per-object-cap 10 GB per file source 100 files per record by default. 'For data governance reasons ... all data must belong to at least one community.' Files immutable after publication; one-month grace period.
Binding	per-object-cap the per-object cap sets the shard size and therefore the object count; it bounds the total more tightly than any headline quota
Interface	rest InvenioRDM REST (/api/records), OAI-PMH, GitHub integration.
Tooling	curl; the InvenioRDM python client.
Composes with	Mountable via any InvenioRDM wrapper; the 60-second presign makes it a poor CDN origin unless fronted by Cloudflare with a re-resolving shim.
Reliability	Login is ORCID / GitHub / KTH SSO — genuinely open — but deposit requires membership of a KTH community, and the quota-increase email asks which 'organisation, project, or grant' the data belongs to.
Notes	50 GB and 100 files per record by default; 10 GB per file. Quota increase is granted on email request to researchdata@kth.se. Not a hard wall — a record with a 70.4 GB single object exists in the public API, i.e. increases are real and granted.

Free tier	Small test allocations on the NAISS Dardel system can be applied for at any time, are handled locally within one to two weeks, and are free of charge to academic researchers at postdoctoral level or above. unit none; metered on wall-clock; exploratory / test allocation
Price	none stated

Interface	unknown inferred from the tooling the provider documents; not probed
Tooling	not stated
Composes with	The out-of-Sweden exception is the only explicit statement found anywhere in this assignment that a person based abroad can hold a Swedish allocation, and it still requires a Swedish group.
Reliability	no reliability event recorded
Notes	Recorded because it is the one national system that states in its own documentation that a person based outside the country can receive an allocation, which is the exact question this assignment asked. The condition is a Swedish research group or supervisor, so the door is a collaboration rather than an application. PDC publishes no size for the small test allocation, so the field is null.
