1TB or 2TB SSD: what capacity for a gaming PC in 2026?

When configuring a gaming PC, the storage question always comes at the end of the list, after the processor and graphics card. However, it is often what determines daily convenience: a saturated SSD forces you to constantly uninstall and reinstall your games. So, 1 TB or 2 TB in 2026? The answer depends on your game library, but also on a very specific market context this year.

How much do games really weigh in 2026?

Game sizes have been climbing steadily in recent years, driven by high-resolution textures and uncompressed audio. Some orders of magnitude observed on current installations:

The math is simple: with Windows 11 and its updates (about 60 to 80 GB to plan for over time), daily software, and a dozen games installed, including a few AAAs, a 1 TB SSD fills up in a few months. You must also keep 10 to 15% free space to preserve SSD performance and leave room for updates.

1 TB: the right starting point for most gamers

A 1 TB NVMe SSD remains the standard for gaming configurations, and for good reasons:

• It comfortably accommodates Windows, your software, and 5 to 8 games, including several AAAs.
• If you play mainly 2 or 3 competitive titles, you are very far from saturating it.
• In 2026, with storage prices rising sharply, it represents the best budget-to-use balance at purchase.

The typical profile: the player who alternates between a few regular multiplayer games and a solo AAA from time to time, even if it means uninstalling the previous one once finished. For this profile, 1 TB is enough without frustration.

2 TB: comfort for large libraries

The move to 2 TB is justified in several scenarios:

• You keep everything installed: if uninstalling a game breaks your heart and your Steam library exceeds twenty active titles, 2 TB will save you from constant space management.
• You play simulators: a single flight simulator with its extensions can occupy the equivalent of three AAAs.
• You create content: video captures, editing, streaming... high-quality recordings fill a disk at high speed.
• You want to plan ahead: with games becoming ever heavier, 2 TB buys you several years of peace of mind.

The 2026 context: storage prices under pressure

It is impossible to talk about capacity without mentioning the current market. Since the end of 2025, the global shortage of NAND memory has caused SSD prices to rise dramatically—some popular models have seen their price double in one year. This situation changes two things in the reasoning:

• The extra cost of 2 TB has increased in absolute value: the gap between 1 TB and 2 TB, once reasonable, now weighs more heavily on a tight budget. On an entry-level configuration, these euros are often better invested in the graphics card.
• Waiting is not necessarily a good strategy: industry analysts do not anticipate a rapid easing of NAND prices. Buying the capacity you need now, no more and no less, is the most rational approach.

The clever strategy: upgradeable 1 TB

Good news: storage is the easiest component to upgrade. Most recent motherboards have two or more NVMe slots. Starting with 1 TB today and adding a second SSD in a year or two, when your needs have grown (and perhaps at better prices), is a strategy with no drawbacks: no reinstallation, no cloning, the new disk is simply added to the first to install games on it.

NVMe or SATA for the second disk?

If you supplement later, prioritize an NVMe if your motherboard has a free slot: recent game loading times benefit from it, and the price gap with SATA has narrowed. The SATA SSD remains relevant only for cold storage (photos, videos, archives) or if all your NVMe slots are occupied. As for the mechanical hard drive, it only has a place for archiving large volumes.

Conclusion: capacity according to your profile

In summary: 1 TB for the majority of players, especially those who play a limited number of titles in parallel or who watch their budget in a tense market. 2 TB for collectors, simulator fans, and content creators who know they will fill the space. And when in doubt, upgradeable 1 TB: your motherboard keeps a free slot for the future.
