Quick answer

PCIe Gen4 is the right interface for a gaming SSD in 2026: it clears every game and DirectStorage requirement, runs cooler than Gen5 and costs far less. A 2TB Gen4 NVMe drive with DRAM is the pick for most UK builds. The Crucial T500, WD_BLACK SN850X and Samsung 990 Pro lead; buy whichever is cheapest per terabyte above.

Why Gen4 is the gaming default

Gen4 hits the sweet spot of speed, price and heat. It meets Microsoft's DirectStorage bar, loads games as fast as anything you can buy today in practice, and does it without the extra cost and temperature of Gen5. For a gaming PC or a PS5, Gen4 is the sensible choice.

Honest trade-off

The only reason to skip Gen4 for Gen5 is if you do heavy sequential work outside gaming. For pure play, Gen4 is faster value and the money is better spent on capacity or your graphics card.

Frequently asked questions

Is Gen4 fast enough for gaming?

Comfortably. Gen4 NVMe drives reach around 7,000 MB/s and meet every DirectStorage requirement. Games do not saturate that, so a good Gen4 drive games identically to a pricier Gen5 one.

Gen4 or Gen5 SSD for gaming?

Gen4. It is cheaper, cooler and just as fast in games. Gen5 only pays off for heavy sequential workloads like large file transfers or professional content work, not gameplay.

What is the best Gen4 gaming SSD?

A 2TB Gen4 drive with DRAM such as the Crucial T500, WD_BLACK SN850X or Samsung 990 Pro. Sort by price per terabyte to pick the best value.

Do all motherboards support Gen4 SSDs?

Most boards from the last few years do, and Gen4 drives are backward compatible with Gen3 slots (running at Gen3 speed). Check your motherboard M.2 slot specification if unsure.

Does a Gen4 SSD need a heatsink?

The M.2 heatsink included with your motherboard is enough for a Gen4 drive in a desktop. A bare drive under sustained load can benefit from one; a PS5 requires a low-profile heatsink.
