Best value storage and memory in the UK

Storage and memory sit in separate tabs and are never ranked against each other, because pounds per terabyte and pounds per gigabyte are different scales and a combined table would produce an ordering that means nothing.

The 90-day low is the lowest price we recorded for that exact product in the last 90 days. A product appears only once we hold at least 10 observations for it in that window, because a low drawn from three data points describes our sampling rather than the product.

Only new, in-stock items are included. A used or renewed drive at half price would sit at the top of a per-terabyte table and quietly make the whole ranking misleading.

Limitations. These are Amazon UK listing prices for the products we track, not the whole UK market, and they exclude discounts applied at checkout. Being at a 90-day low says a product is cheap against its own recent past, which in a rising market is not the same as cheap.

For the direction of the market as a whole rather than individual products, see the UK PC component price index.
