Most everyday PC users are well served by 500GB to 1TB of storage, while gamers who install several current large titles should plan for 1TB to 2TB or more, since many modern games individually take up 50 to 150GB or more of space. Content creators working with large video or design files should budget even higher.
- 500GB-1TB covers general use: Windows, browsing, office work, and light gaming.
- Gamers with several large modern titles installed should plan for 1-2TB.
- Individual modern games commonly range from 50-150GB or more each.
- A smaller fast boot drive plus a larger secondary drive is a common approach.
Storage Needs by Use Case
| Use case | Recommended storage |
|---|---|
| General use: browsing, office work, light gaming | 500GB-1TB |
| Regular gaming with several current titles installed | 1-2TB |
| Heavy gaming library or content creation | 2TB+ |
| Video editing, large project files | 2-4TB or more, often across multiple drives |
Why Modern Games Take Up So Much Space
Current AAA games commonly range from 50GB to over 150GB each, driven by high-resolution textures, extensive voice acting, and increasingly large open worlds, a trend tracked by TechPowerUp. Installing just five or six current large titles can easily consume 500GB to 1TB on its own.
Windows and Software Overhead
Windows itself, along with updates, drivers, and commonly used software, typically consumes 30-60GB, leaving less usable space than a drive’s advertised capacity suggests. Factor this in when sizing your primary drive, especially on smaller-capacity SSDs.
Should You Use One Drive or Multiple?
A common and cost-effective approach uses a smaller, faster NVMe SSD, around 500GB-1TB, for Windows and your most-played games, paired with a larger secondary drive, either a bigger SSD or a more affordable HDD, following the comparison in SSD vs HDD, for your broader game library and file storage.
How to Check Your Current Usage
Open Settings, then System, then Storage to see a breakdown of what’s currently using space on your PC, following the same general check described in how to check PC specs. This gives a concrete baseline before deciding how much additional storage to add.
Planning for Future Growth
Since game and file sizes have consistently trended larger over time, buying somewhat more storage than your current immediate need, rather than the exact minimum, avoids needing an upgrade again soon after your initial purchase.
Practical rule of thumb: count your top 5-10 most-played or planned games’ listed install sizes, add Windows overhead, then add reasonable headroom, rather than guessing at a round number.

Frequently Asked Questions
Is 500GB enough storage for a gaming PC?
It can work for a small game library, but most gamers with several current large titles installed will want 1TB or more.
How much space does Windows itself use?
Typically 30-60GB including updates and common drivers, which is worth factoring into your total storage planning.
Should I use one large drive or two smaller ones?
A smaller fast SSD for Windows and top games, paired with a larger secondary drive for the rest, is a common and cost-effective approach.
How do I check how much storage I’m currently using?
Open Settings, then System, then Storage, for a detailed breakdown of what’s using space on your PC.
