How we work these numbers out
TerabytePrices records the price of every one of the 1,321 storage drives we track on Amazon UK once a day and keeps the result. That gives us 233 days of price history to compare against, so a "drop" here means the price is genuinely lower than what we recorded earlier — not a discount calculated from an inflated list price. Prices change constantly; the figures below were correct on 23 July 2026 and we relink to Amazon so you can check the live price.
Prices and availability are taken from the Amazon UK Product Advertising API and were accurate at the time of writing. As an Amazon Associate we earn from qualifying purchases — this never affects which products we rank or how we rank them, which is decided entirely by the price data.
