Which Amazon stores do the prices on Disk Prices (US) come from?

Disk Prices (US) pulls its listings from Amazon marketplaces, not from a single store. The site's data-source line names amazon.com, amazon.co.uk, amazon.de, amazon.es, amazon.fr, amazon.it, amazon.ca, amazon.com.au, amazon.in, amazon.se and amazon.ie. So a row you see can originate from the US site or from a European, Canadian, Australian, Indian or Irish Amazon storefront. Treat every figure as a snapshot taken when the data was collected, and confirm the live price on the linked Amazon listing before you buy.

What the marketplace list means for a given row

The site presents one combined table rather than separate tables per country. Each row carries an affiliate link out to the Amazon listing, and the price shown is whatever that listing displayed at collection time.

Two consequences follow:

• Currency is not normalized in the display. A listing sourced from amazon.co.uk, amazon.de or amazon.fr is priced in that marketplace's currency, while amazon.com and amazon.ca listings use theirs. A low number in the price column is not automatically a cheaper drive — check which store the row links to.
• Availability is regional. A drive offered on amazon.de may not ship to a US address, and the same model on amazon.com may carry a different price or be out of stock. The comparison is useful for spotting models and price-per-TB outliers, not for assuming you can buy any row from any country.

A concrete example

Suppose you filter to internal 3.5" drives and sort by price per TB. The cheapest rows might include a high-capacity tape cartridge (the excerpt shows LTO-9 18 TB cartridges at roughly $5 per TB) alongside flash media and SSDs. Before acting on the top row, open its affiliate link: if it resolves to amazon.co.uk, the total is in pounds and delivery to your location may differ from the US listing of the same product.

How to use the marketplace mix when comparing

1. Set your filters first — condition (new/used), capacity range, and the technology or form factor you actually need. The site's category list is broad: rotational drives, internal and external SSDs, M.2 SATA and NVMe, U.2/U.3, plus memory (DDR4/DDR5 in UDIMM, SODIMM and RDIMM), removable flash, optical and tape.
2. Read the price-per-TB column, then check the source store behind the affiliate link.
3. Verify on Amazon — confirm the current price, the seller, the warranty term shown in the row, and whether the item ships to you.
4. Re-check before buying. Prices on Amazon change; the site's figures are historical snapshots, not live quotes.

Common sticking points

• Mixing currencies in one sort. Because rows from different marketplaces sit in the same table, a straight sort by price can put a foreign-currency bargain at the top. Convert before you conclude it is cheaper.
• Warranty and condition fields vary by listing. The table shows warranty where the listing provides it (for example "2 years" on some tape packs) and marks condition as New or Used. Do not assume these carry over between the same product on different Amazon stores.
• Affiliate links. The site states it is supported by paid affiliate links, so the outbound link is how you reach the actual Amazon page — use it to confirm details rather than relying on the table alone.
