Azure Files uses file shares as the unit of performance. Unlike Blob/Table storage, partitioning isn't controlled via naming — performance depends on share size, tier, protocol, and IOPS/throughput limits. This simulator helps you model whether your share configuration meets workload needs.
Files, IOPS, and throughput allocated per share
| Tier | Baseline IOPS | IOPS Formula | Max Throughput | Max Share Size |
|---|---|---|---|---|
| Premium (SSD) | 3,000 | 3,000 + 1 × provisioned GiB | ~100 MiB/s + 0.04 × GiB | 100 TiB |
| Transaction Optimized | 10,000 | Up to 10,000 | Up to 300 MiB/s | 100 TiB |
| Cool | 10,000 | Up to 10,000 | Up to 300 MiB/s | 100 TiB |
