We rank every 3TB drives by real cost per terabyte (£/TB) — the live Amazon.co.uk price divided by capacity — so the best value appears at the top. Prices refresh several times a day from Keepa, with 24-hour movement and all-time-low flags.
What is the cheapest 3TB drives drive right now?
The drive at the top of the table above is the cheapest 3TB drives option by £/TB at the moment. Larger capacities usually cost less per terabyte, so it is worth comparing 3TB drives against the next size up before you buy.
Is a 3TB drives drive good value?
Value depends on £/TB, not the sticker price. Use the ranking above to compare, and open any drive for its full Keepa price history to check whether today's price is genuinely low.
What is a 3TB drives drive good for?
It comes down to how much you store — see our storage sizing guide. As a rule, buy one size up if the £/TB is similar, so you do not run out sooner.
