About harddisc.net
An independent, reader-supported tracker that ranks every kind of digital storage by the one number that decides value: real cost per terabyte.
Our mission
Storage is one of the few purchases where the headline price actively lies to you. A drive with a bigger sticker is frequently far cheaper storage than a small, ‘affordable’ one — because what you are really buying is capacity, and capacity is measured in terabytes, not in dollars on a shelf edge. harddisc.net exists to make that comparison effortless: we translate every product into its real cost per terabyte and rank the entire market by it, so you stop overpaying for the storage you need.
What this site does
We continuously track more than 3,200 storage products across 11 categories — from internal hard drives and SSDs to NVMe, enterprise & SAS, LTO tape, optical media, memory cards, USB flash and RAM. Every product is normalised to its real cost per terabyte and ranked cheapest-first. You can browse a single category, put two to four products head-to-head in our comparison tool, size a build with the capacity calculator, or jump straight to the master $/TB rankings that span every category at once.
We are not a store. We hold no inventory, set no prices and ship nothing. We are a comparison layer that points you at whichever retailer currently offers the cheapest terabyte for what you actually want to buy.
Editorial independence
The ranking is the product, so its integrity is non-negotiable. Products are ordered by their real cost per terabyte and by editorial judgement about whether a drive is fit for its job — never by what a retailer pays us. A used enterprise drive that beats a brand-name consumer model on $/TB sits above it, full stop, even if the cheaper drive earns us nothing. We explain exactly how the figures are produced on our how we test page, so you can check our working rather than take our word for it.
How the site makes money
harddisc.net is free to use and carries no paywall, no account and no newsletter wall. When you follow a link to a retailer and buy something, we may earn an affiliate commission at no extra cost to you. That commission is how the site stays online — and it has zero influence on rankings, because the ordering is computed from price and capacity before any commission is ever considered. Not every outbound link is even an affiliate link. The full details, written plainly, live in our affiliate disclosure.
Who it is for
If you are building a NAS, archiving a media library, planning a backup strategy, upgrading an old laptop or just trying not to overpay for a USB drive, this site is built for you. We assume you would rather see the cheapest honest terabyte than the loudest banner. If you spot an error in our data, we genuinely want to hear it — contact us and we read every correction.
