## Performance scaling

Scaleway File Storage architecture follows a "pay-as-you-grow" model where IOPS and throughput scale linearly as you provision more capacity for a file system. This guarantees consistent and predictable performance that you can adjust according to your needs.

The performance of a file system may vary due to factors such as the number of attached Instances, the attached Instance type, and the workload. Refer to the [dedicated guidelines](/file-storage/reference-content/file-system-instance-selection/) for more information.

Both IOPS and throughput reach their maximum values at 2 TB of provisioned capacity. Provisioning beyond 2 TB increases available storage, but does not further increase performance.

### IOPS

Baseline
: 1,000 IOPS at 25 GB

Scaling rate
: +12 IOPS per provisioned GB

Maximum
: 25,000 IOPS at 2 TB

IOPS scale linearly between the baseline and the maximum. Beyond 2 TB of provisioned capacity, IOPS remain capped at 25,000.

**Example:** A file system provisioned with 100 GB delivers approximately 1,900 IOPS (1,000 + 75 * 12).

### Throughput

Baseline
: 4 MB/s at 25 GB

Scaling rate
: +0.1 MB/s per provisioned GB

Maximum
: 200 MB/s at 2 TB

Throughput scales linearly between the baseline and the maximum. Beyond 2 TB of provisioned capacity, throughput remains capped at 200 MB/s.

**Example:** A file system provisioned with 100 GB delivers approximately 11.5 MB/s (4 + 75 * 0.1).
