Storage matters more than most server owners realize. The difference between an NVMe SSD and a spinning hard drive is not just file transfer speed; it directly affects chunk loading times, world saves and how many players your server can handle.
The numbers
| Metric | HDD (7200 RPM) | SATA SSD | NVMe SSD |
|---|---|---|---|
| Sequential read | 100 to 150 MB/s | 500 to 550 MB/s | 3,000 to 7,000 MB/s |
| Sequential write | 100 to 150 MB/s | 400 to 500 MB/s | 2,000 to 5,000 MB/s |
| Random 4K IOPS | 75 to 150 | 50,000 to 100,000 | 500,000 to 1,000,000 |
| Latency | 5 to 10 ms | 0.05 to 0.1 ms | 0.01 to 0.02 ms |
Random IOPS and latency matter most for game servers, because chunk loading, save operations and database queries are random access patterns, not sequential.
Impact on specific games
Minecraft
Chunk loading is IO-intensive. When a player walks into unloaded territory, the server reads chunk data from disk. On an HDD, this causes visible lag (blocks loading slowly, entities popping in). On NVMe, chunks load instantly.
FiveM
FiveM databases (MySQL/MariaDB) benefit enormously from fast storage. Every player action (moving, inventory, saving) triggers database queries. NVMe keeps query times under 1ms.
Rust / ARK / Palworld
World saves are large (100 MB to 1 GB+). On an HDD, saving causes a server freeze of 1 to 5 seconds. On NVMe, the same save completes in under 100 ms with no noticeable impact.
When does storage type not matter?
- Small servers: a 5-player Minecraft server with a small world fits entirely in RAM. Disk speed is irrelevant.
- Factorio: the game runs entirely from RAM after initial load. Storage only matters during saves.
- Idle servers: a server with nobody online does minimal IO regardless of storage type.
Is NVMe worth the extra cost?
Yes, for any server with more than 10 active players. The difference is measurable in chunk loading times, save duration and overall responsiveness. At HostValues, all plans use NVMe storage at no extra cost.
Can a slow disk cause TPS drops?
Yes. In Minecraft, chunk loading on a slow disk blocks the main thread, causing TPS drops. Paper's async chunk loading mitigates this, but the disk still limits throughput.
All plans at HostValues use NVMe SSDs for maximum performance.
