Storage Comparison

Find the Best Storage Prices

Live prices from Amazon across all regions. Compare SSDs, HDDs, NVMe drives, RAM, and more.

How It Works

Filter by type, region & condition

Narrow down by drive type — HDD, SSD, NVMe, RAM, and more — plus Amazon region and new vs. used condition.

Sort by price per TB

We rank every listing by price per terabyte, not sticker price, so a $400 8TB drive and a $90 2TB drive can be compared honestly.

Buy directly on Amazon

Every listing links straight to the product page on Amazon. We don't sell anything ourselves — we just track prices.

What We Track

Disk Scout tracks internal & external hard drives, SATA/NVMe SSDs, RAM, memory cards, optical media, and LTO tape — pulled directly from Amazon's live listings and refreshed automatically throughout the day, so the table above reflects real, current prices rather than a stale snapshot.

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.
