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. This never affects rankings — every table is sorted purely by price per TB, with 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?

Every 4 hours, automatically. See our Methodology page for details on how we collect and calculate prices.

What does "price per TB" mean?

Total price divided by usable capacity, so drives of very different sizes can be compared fairly. 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.
