Frequently Asked Questions
Is Disk Scout affiliated with Amazon?
No. Disk Scout is an independent, third-party price tracker. We are not owned by, operated by,
or affiliated with Amazon.com, Inc. or its affiliates.
How does Disk Scout make money?
As an Amazon Associate, Disk Scout earns from qualifying purchases when you click through and buy
on Amazon. Comparison tables default to price per TB and can be filtered or sorted. There is no paid placement.
Why do prices differ between regions?
Amazon sets independent pricing, tax, and currency for each marketplace, so the same drive can
cost meaningfully different amounts by region. We show each region separately rather than
converting to one currency, since live exchange rates would make the comparison misleading.
How often are prices updated?
US price refresh jobs run every six hours. Check the timestamp on each offer; not every listing updates in every run. See our Methodology page for details on how we collect and calculate prices.
What does "price per TB" mean?
Price divided by the listed decimal capacity (1TB = 1,000GB), before formatting and RAID overhead. Compare compatible drives in the same condition.
Full explanation in our price-per-TB guide.
Can I save listings to compare later?
Yes — click the heart icon on any listing to save it locally in your browser (no account needed),
then filter to "Saved" to compare your shortlist.
