Quick answer

The cheapest option on Amazon.co.uk right now is the Ediloca EN760 SSD with Heatsink 4TB PCIe Gen4, NVMe M.2 2280, 3D at £279.99 (£70.00/TB). For gaming, buy Gen4. A good Gen4 NVMe drive loads games as fast as a Gen5 one in practice, costs less and runs cooler, because games and DirectStorage do not use Gen5 bandwidth. Choose Gen5 only if you also do heavy file or content work. The live prices below show today's Gen4 and Gen5 options so you can weigh the premium.

Choose Gen4 if / Choose Gen5 if

  • Choose Gen4 if you mainly game, want the best value, or run a PS5.
  • Choose Gen4 if your motherboard lacks a Gen5 M.2 slot.
  • Choose Gen5 if you edit video or move very large files regularly.
  • Choose Gen5 if you want maximum future-proof headroom and can cool it.

The verdict

For a gaming build, Gen4 wins on value and loses nothing you can feel. Gen5 is a genuine upgrade only for bandwidth-heavy work. Compare the live prices above: if the Gen5 premium is large, a Gen4 drive plus more capacity is the better buy.

Frequently asked questions

Is Gen5 faster than Gen4 for gaming?

On paper yes, in games barely. Gen5 doubles peak bandwidth, but games do not read that fast, so real load times are almost identical. The extra speed helps large file transfers, not gameplay.

Should I buy Gen4 or Gen5 for a gaming PC?

Gen4 for almost everyone. It is cheaper, cooler and just as fast in games. Buy Gen5 only if you edit video or move large files, or specifically want future-proof headroom.

Does Gen5 improve DirectStorage load times?

Not meaningfully over Gen4. DirectStorage is designed around fast NVMe in general; a quality Gen4 drive already meets its needs, and Gen5 adds little in real games.

Is a Gen5 SSD worth the extra cost for gaming?

Usually not. The price premium and extra heat buy speed you will not notice while playing. Put the saving toward more capacity or a better GPU.

Will Gen5 matter more in future games?

Possibly, but slowly. Consoles set the pace and they use Gen4-class speeds, so Gen4 will remain plenty for gaming for years. Buying Gen5 now is optional insurance, not a requirement.
