Game Storage Calculator (Library Capacity & Space Planner)
Plan game library storage, DLC expansions, shader cache, and SSD free-space provisioning buffers.
TL;DR: Game Storage Calculator sums storage installations across selected AAA, AA, Indie, and Battle Royale titles while budgeting for DLC expansions, shader caches, and SSD provisioning buffers.
How much SSD storage do you need for a modern PC game library?
Direct Answer: For a modern gaming PC, a 1TB SSD is the minimum recommended baseline (fitting the OS plus 4–6 major AAA games). A 2TB NVMe SSD is the recommended sweet spot, allowing 10–15 major titles (such as Call of Duty, Cyberpunk, and Baldur's Gate 3) plus updates and a 15% free-space buffer.

How to Use the Game Storage Calculator
- Select or add the game titles you actively play or plan to install.
- Include estimated DLC expansions and future update buffers.
- Add Windows OS overhead and recommended 15% SSD provisioning free-space buffer.
- View your total required storage in GB/TB and recommended drive capacity.
Pro Tips & Best Practices
- Modern AAA games (like Call of Duty: Warzone, Ark, and Baldur's Gate 3) frequently exceed 120GB to 175GB each.
- Always leave 15% to 20% free space on NVMe SSDs to allow SLC caching algorithms to maintain peak write speeds.
- Shader caches and GPU driver pre-compilations can consume an additional 10GB to 25GB of drive storage over time.

Frequently Asked Questions
- Modern games feature uncompressed 4K texture packs, multi-language uncompressed audio files, complex 3D geometry meshes, and pre-baked lighting maps that require massive storage volumes.
- Filling an SSD above 85–90% exhausts its dynamic SLC write cache and blocks the drive controller's TRIM and garbage collection routines, causing write speeds to drop by up to 80% and increasing drive wear.
- While a single fast 2TB NVMe SSD is fine for most users, having a dedicated OS drive (e.g. 500GB) separate from your Games drive (e.g. 2TB) allows clean Windows reinstalls without redownloading your entire game library.
- A clean Windows 11 installation takes approximately 25GB–35GB of storage, expanding to 50GB–60GB over time with updates, pagefiles, hibernation files, and system restore points.
- Older indie and retro titles run fine on HDDs. However, newer AAA games require an SSD to stream high-resolution textures in real time without severe hitching and stuttering.
- Competitive tactical shooters are well-optimized: Valorant requires ~35GB and CS2 requires ~38GB of drive storage space.
- Steam and other launchers often require temporary drive space equal to the full game installation size to unpack and stage major updates before deleting temporary files.
