Storage is the most overlooked resource in game server hosting. Everyone worries about CPU clock speed and RAM, but when your Minecraft world hits 25 GB and auto-save freezes the server for 8 seconds, storage speed becomes the bottleneck. Here is a practical guide to sizing NVMe storage for game servers, managing world saves, and building a backup strategy that does not fill your drive.
How Big Do Game Worlds Actually Get?
World sizes vary dramatically by game and playstyle. A vanilla Minecraft world with 10 active players exploring regularly grows by 500 MB to 1 GB per month. Modded Minecraft packs like All The Mods 9 can reach 15-25 GB within 60 days due to custom dimensions, chunkloaders, and machinery data. Valheim worlds are modest at 100-500 MB, but Palworld saves can balloon to 2-5 GB because the game saves every Pal’s state and every base structure individually. ARK: Survival Ascended maps easily exceed 30 GB with mods and extensive building.
Plan your storage based on the game and expected playtime. A dedicated server running three different game worlds needs at least 500 GB of NVMe storage to have breathing room. Our comparison table shows dedicated server plans with NVMe storage options so you can match capacity to your game library.
NVMe vs SATA SSD: The Real-World Difference
NVMe drives are not just faster on paper — they matter for specific game server operations. World saves in Minecraft and ARK are sequential writes; an NVMe drive at 3,500 MB/s finishes a 10 GB world save in under 3 seconds, while a SATA SSD at 550 MB/s takes 18 seconds. During that 18-second window, the server thread is blocked, and every player experiences lag. For games with frequent auto-saves (ARK saves every 15 minutes by default), NVMe is not a luxury — it is the difference between smooth gameplay and constant micro-stutters.
Random read performance matters too. When players teleport or chunks load, the server issues hundreds of small random reads. NVMe handles these at 500K+ IOPS, while SATA SSDs cap around 100K IOPS. The result: faster chunk loading, smoother exploration, and fewer complaints about terrain pop-in.
The Backup Math Nobody Does
Here is the storage trap most server owners fall into: you have a 500 GB NVMe drive. Your game worlds take 80 GB. You configure daily backups, keeping 7 days of retention. That is 80 × 7 = 560 GB of backups alone — more than your drive can hold. The solution is simple but often overlooked:
- Local backups: Keep only 2-3 days of recent backups on the NVMe drive. Use restic or borg to deduplicate and compress — you will typically save 60-70% space.
- Offsite backups: Push older backups to S3-compatible storage or a separate backup server. Automate this with a cron job that runs after the local backup completes.
- Snapshot strategy: Take a full backup once a week, then daily incrementals. This keeps your local footprint small while still giving you point-in-time recovery.
Storage Sizing Cheat Sheet
- 1-2 vanilla Minecraft servers: 250 GB NVMe (worlds + 3 days of backups)
- 1-2 modded Minecraft servers: 500 GB NVMe
- 3-5 game servers (mixed games): 1 TB NVMe
- 5+ servers with heavy mods: 2 TB NVMe or dual-drive setup (OS on 250 GB, game data on 1-2 TB)
Storage is cheap compared to the cost of losing a world your community has built for months. Size your NVMe correctly, automate your backups, and test your restore process before you need it. Compare dedicated server storage options on our table to find the right balance of speed and capacity.
