For most gaming PCs, buy a good 2TB PCIe 4.0 TLC drive before paying extra for PCIe 5.0. Our default pick is the Samsung 990 Pro; the WD Black SN850X is the best price-sensitive alternative, and the Crucial T500 is the third drive to check when it is discounted.
- 2TB is the sweet spot for your game library
- Your motherboard has a PCIe 4.0 M.2 slot
- You want a mature high-performance drive without Gen5 heat and pricing
- You only need a cheap secondary drive for infrequently played games
- Your platform is limited to PCIe 3.0 and upgrade plans are distant
- A 4TB model offers much better cost per terabyte for your library

Why 2TB is such a useful gaming capacity
Modern game installs can easily run into triple-digit gigabytes. A 1TB system drive can feel cramped once Windows, launchers, captures and a handful of large games share the same space. Two terabytes gives most players enough breathing room without paying the steep price of top-end 4TB models.
Best overall: Samsung 990 Pro 2TB
Samsung's current data sheet rates the 2TB 990 Pro at up to 7,450 MB/s reads and 6,900 MB/s writes, with TLC NAND, DRAM cache and a five-year limited warranty. It remains a mature, fast Gen4 choice and is still Tom's Hardware's overall/gaming SSD pick in 2026.
Why buy it: balanced premium performance, excellent software support and broad PC/PS5 suitability. Why skip it: another quality Gen4 drive can be the better purchase if Samsung pricing jumps.
Best alternative: WD Black SN850X 2TB
The SN850X is close enough in real-world class that price should often decide it. SanDisk lists up to 7,300 MB/s reads and 6,600 MB/s writes for the 2TB model, with 1,200 TBW endurance and a five-year warranty. Heatsink variants also make it an easy PS5 shortlist.
Best third option: Crucial T500 2TB
Crucial rates the 2TB T500 at up to 7,400 MB/s reads and 7,000 MB/s writes with TLC NAND and 1,200 TBW endurance. It is exactly the sort of drive to check when Amazon pricing makes the headline Samsung and WD models look expensive.
Do gamers need PCIe 5.0?
Usually not. Gen5 drives can be spectacular in sequential benchmarks and heavy workstation tasks, but game performance is not doubled just because peak transfer speed is. A mature Gen4 SSD still gives fast loading, strong responsiveness and lower platform demands for most gaming builds.
Heatsink or no heatsink?
On PC, many motherboards already include an M.2 heatsink. Buying a second bulky heatsink can create fit problems, so check the board first. For PS5, make sure the installed drive has appropriate cooling and fits the console's M.2 bay requirements.
How to shop this guide
We deliberately do not publish a fixed Amazon price because SSD pricing moves constantly. Open all three current listings, compare the same 2TB capacity and heatsink configuration, and buy the strongest value that day.
Samsung 990 Pro 2TB
Our default premium Gen4 pick when pricing is competitive.
WD Black SN850X 2TB
Nearly interchangeable for gaming; particularly good when sale pricing or heatsink availability wins.
Crucial T500 2TB
Fast TLC Gen4 drive that can become the value winner when discounted.
Amazon prices and availability change frequently, so we show a current Amazon UK link rather than copying a price that may be stale.
