Quick answer

The cheapest option on Amazon.co.uk right now is the OWC Express 1M2 Portable SSD NVMe Thunderbolt Enclousure 40Gbps at £89.99 (£5.62/TB). 4TB is for players who never want to uninstall: it holds a huge library and future 150GB+ releases. A 4TB PCIe Gen4 NVMe drive is the pick; the price per terabyte is higher than 2TB, so buy 4TB for the convenience, not the value. The WD_BLACK SN850X 4TB, Crucial T500 4TB and Samsung 990 Pro 4TB are the strong options in the table above.

When 4TB makes sense

  • Large installed libraries: keep 40 to 60 big games ready to play.
  • Content plus gaming: room for game captures, mods and projects.
  • Future-proofing: headroom for the next wave of 150GB+ titles.
  • Not ideal if value per terabyte is your priority: 2TB wins there.

Honest trade-off

4TB is convenience, not value: expect to pay more per terabyte than a 2TB drive. If you can live with occasionally uninstalling a game, a 2TB drive saves money; if you want it all installed, 4TB is worth it.

Frequently asked questions

Is a 4TB SSD worth it for gaming?

Do 4TB gaming SSDs need special cooling?

On a desktop the board heatsink is enough. Some 4TB drives are double-sided and run a little warmer, so ensure your motherboard M.2 heatsink makes good contact.
