Preservation you can verify,
not just trust.
Flat $4.99/TB. Integrity verified approximately every 24 hours, not once a year. No retrieval fees, no egress, 11 nines durability.

A fixity report is a snapshot. Decay happens between snapshots.
Preservation depends on knowing the bits are unchanged. Most storage only tells you once a year — and charges you to find out. Neither the gap nor the bill belongs in a serious preservation program.
A year is a long time to not know.
A once-a-year fixity review confirms integrity on the day it runs. For the other 364 days the collection is unverified. Silent corruption that lands in month two surfaces ten months later — if the review even catches it.
Verifying your archive is a metered read.
On metered tiers, every fixity review is a full-collection read priced per GB in retrieval and egress. The more thoroughly you preserve, the more it costs to prove you did — so teams check less than they should.
Proprietary tiers complicate the future.
Preservation is measured in decades. Storage tiers with restore delays, retrieval classes, and per-request semantics add operational risk to a workload whose entire point is to be simple, readable, and intact far into the future.
10 TB collection. One fixity review a year.
Same preservation workload, four providers. Monthly storage, the cost of reading the collection back to verify it, and whether integrity is actually checked.
| Provider | Storage 10 TB/mo | Retrieval + egress | All-in /mo | Integrity verification |
|---|---|---|---|---|
| AWS S3 Standard | $236 | $0.09/GB | $311 | No |
| AWS Glacier Deep Archive | $10 | $0.02 + $0.09/GB | $102 | No |
| Wasabi | $70 | $0 | $70 | No |
| Fil OneYou | $50 | $0 | $50 | ~24 h |
Scenario: 10 TB collection with one full fixity read per year, amortized monthly. AWS S3 Standard: ≈$236/mo storage ($0.023/GB) + ≈$75/mo amortized fixity (10 TB × $0.09/GB egress per year) ≈ $311/mo. AWS Glacier Deep Archive: ≈$10/mo storage ($0.00099/GB) + ≈$92/mo amortized fixity (10 TB × ($0.02 retrieval + $0.09 egress)/GB per year) ≈ $102/mo. Wasabi: $6.99/TB = $70/mo, no egress. Fil One: $4.99/TB = $50/mo, $0 egress, integrity verified ~24 h. AWS and Wasabi rates from public US price cards, Q2 2026; figures indicative and rounded.
Verification built in. Reading included.
Integrity verification, ~24 h
Every preserved object is re-verified approximately every 24 hours. You do not wait a year for a fixity review to discover that a file changed — the check is continuous and built in.
11 nines durability
Designed for 11 nines of durability. The storage architecture makes bit-loss a detectable, recoverable event rather than a silent one you find at restore time.
$0 retrieval, $0 egress
Reading the collection back — for an audit, a migration, or a patron request — costs nothing. Verifying your archive is no longer a line item you ration.
S3-compatible
Standard GetObject, PutObject, and multipart transfer. Preservation tools, BagIt workflows, and repository software that speak S3 connect without modification.
One rate. $4.99/TB/month.
Storage. That is the whole bill. Integrity verification, 11 nines durability, and free reads are included — verifying the collection never adds a cent.
