1TB or 2TB SSD: What Capacity for a Gaming PC in 2026?

When configuring a gaming PC, storage always comes last on the list, after the processor and graphics card. However, it often dictates daily comfort: a saturated SSD forces you to constantly uninstall and reinstall your games. So, 1TB or 2TB 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?

The size of games has been steadily increasing in recent years, driven by high-resolution textures and uncompressed audio. Here are some typical sizes observed in current installations:

The math is simple: with Windows 11 and its updates (approximately 60 to 80 GB over time), daily software, and a dozen installed games including a few AAA titles, a 1TB SSD fills up in a few months. You also need to keep 10 to 15% free space to maintain SSD performance and allow for updates.

1TB: The Right Starting Point for Most Gamers

A 1TB NVMe SSD remains the standard for gaming setups, and for good reason:

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

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

2TB: Comfort for Large Libraries

Upgrading to 2TB is justified in several scenarios:

• You keep everything installed: If uninstalling a game pains you and your Steam library exceeds twenty active titles, 2TB will save you from constant space management.
• You play simulators: A single flight simulator with its extensions can take up the equivalent of three AAA titles.
• You create content: Video captures, editing, streaming... high-quality recordings fill a disk very quickly.
• You want to be future-proof: With ever-heavier games, 2TB buys you several years of peace of mind.

The 2026 Context: Storage Prices Under Pressure

It's impossible to discuss capacity without mentioning the current market. Since late 2025, the global NAND memory shortage has caused SSD prices to skyrocket—some popular models have seen their prices double in a year. This situation changes two things in the reasoning:

• The extra cost of 2TB has increased in absolute terms: The difference between 1TB and 2TB, 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 Smart Strategy: Expandable 1TB

Good news: storage is the easiest component to upgrade. Most recent motherboards have two or more NVMe slots. Starting with 1TB 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 drive simply adds to the first one for installing games.

NVMe or SATA for the Second Drive?

If you're upgrading later, prioritize an NVMe if your motherboard has a free slot: recent games benefit from faster loading times, and the price difference with SATA has narrowed. A SATA SSD remains relevant only for cold storage (photos, videos, archives) or if all your NVMe slots are occupied. As for mechanical hard drives, they are now only suitable for archiving large volumes.

Conclusion: Capacity According to Your Profile

In summary: 1TB for the majority of gamers, especially those who play a limited number of titles simultaneously or are watching their budget in a tight market. 2TB for collectors, simulator enthusiasts, and content creators who know they will fill the space. And when in doubt, an expandable 1TB: your motherboard keeps a slot free for later.
