A fixity report is a snapshot. Decay doesn’t wait for the next one.
Preservation depends on knowing the files 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 archival 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 — or one every day.
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 | ~$75 | $311 | No |
| AWS Glacier Deep Archive | $10 | ~$92 | $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 to authenticate that a file is unchanged. Checks are continuous and built in to storage.
11 nines durability
Distributed, redundant architecture with no single point of failure. Designed to deliver 11 nines of durability, backed by continuous, audit-ready integrity records.
$0 retrieval, $0 egress
Reading the collection back — for an audit, a migration, or a patron request — costs nothing. Accessing 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.
