Modern games are storage monsters. A single AAA title can demand 100-200GB, and a handful of them plus Windows can fill a 1TB drive before you have installed your backlog. Planning capacity up front, rather than uninstalling favorites every time something new drops, saves money and frustration. Here is how to size your storage sensibly.
Start With Real Numbers
Budget for Windows and apps first, then games. Windows 11 plus common software realistically uses 60-90GB. From there, estimate your library by how you actually play.
| Item | Typical Footprint |
|---|---|
| Windows 11 + apps | 60-90GB |
| Large AAA game | 100-200GB |
| Mid-size game | 30-70GB |
| Indie / esports title | 2-30GB |
| Recommended free headroom | 15-20% of drive |
Match Capacity to Player Type
The Focused Player (1TB)
If you play one or two big games at a time and finish before moving on, 1TB is workable: roughly 80GB for the OS and 4-6 AAA titles. You will occasionally uninstall, but it is affordable.
The Broad Library (2TB)
The current sweet spot for most gamers. 2TB comfortably holds Windows plus 10-15 games of mixed size with room to breathe, and NVMe pricing at 2TB is excellent. This is the size to buy if you are unsure.
The Collector or Creator (4TB+)
If you keep a big rotating library installed, record gameplay, or edit video, 4TB (or a fast 2TB plus a large secondary drive) prevents constant management. Capture and editing footage alone can consume terabytes.
Leave Headroom, Always
Never plan to fill a drive to the brim. SSDs slow down markedly past 80-90% capacity because the SLC cache shrinks and the controller has less room to work. Sizing so you routinely keep 15-20% free is not wasted space, it is what keeps the drive fast.
Tiering: Fast Drive Plus Bulk Drive
A smart layout is a fast NVMe for the OS and games you are actively playing, paired with a larger, cheaper drive (a big SATA SSD or hard drive) for a game archive, recordings, and backups. You move titles to the fast drive when you play them. This delivers speed where it counts and cheap capacity where it does not.
Frequently Asked Questions
Is one 2TB drive better than two 1TB drives?
For simplicity, a single 2TB drive is cleaner and often cheaper per gigabyte than two 1TB drives, and it avoids splitting your library. Two drives make sense mainly for separating OS from games or adding capacity later without replacing anything.
How much will game sizes keep growing?
They trend upward as textures and audio get richer, though technologies that compress and stream assets help. Planning for the next couple of years, buying 2TB when 1TB feels “enough today” ages far better.
Accounting for Updates, Shaders, and Overhead
The install size a store lists is not the full story. Games download day-one patches that can add tens of gigabytes, compile shader caches that occupy several more, and some launchers keep the compressed installer temporarily during updates, briefly needing extra free space. Budget an extra 10-20% beyond raw install sizes to absorb this churn. A drive planned with zero slack will hit “not enough space” errors mid-update at the worst possible moment.
Future-Proofing Without Overspending
Storage prices per gigabyte fall over time, so there is a balance between buying enough now and overbuying for a future you cannot predict. A sensible rule is to buy the capacity that comfortably covers your current library plus a year of growth, and leave a free M.2 slot or drive bay so you can add cheap capacity later when prices drop, rather than paying a premium today for space you will not use for two years.
Bottom Line
Size storage for how you play, not just today’s installs. Budget ~80GB for Windows, 100-200GB per AAA game, and keep 15-20% free for speed. 2TB is the current sweet spot for most; tier a fast NVMe with a cheap bulk drive if your library or captures run large. Plan ahead and you stop playing storage Tetris.
