Alternatives for benchmarking

AzCopy Bench

Microsoft's official CLI tool for Azure Storage performance benchmarking. Ideal for automated testing, CI/CD pipelines, and high-throughput scenarios where you need precise control over test parameters.

Auto-tuning

Automatically optimizes parallel TCP connections for maximum throughput

Zero disk writes

Downloaded data is discarded, never saved locally

Download benchmark examples

Basic download benchmark:

azcopy bench --mode=Download "https://[account].blob.core.windows.net/[container]?[SAS]"

Rate-limited download test (500 Mbps):

azcopy bench --mode=Download "https://[account].blob.core.windows.net/[container]?[SAS]" \
  --cap-mbps 500

Download mode tests against existing files in your container. Data is streamed but never written to disk.

Frequently asked questions

Does this page measure download speed?

No. This page only generates expiring links to test files. Use the browser-based Azure Download Speed Test for measured progress, elapsed time, Mbps, MiB/s, and region comparisons.

What are these test files for?

Use them for a manual browser download, a download manager, or an external monitoring tool when you need a stable file hosted in a specific Azure region.

How large is each file?

Each file is 100 MiB, or 104,857,600 bytes. The filename remains 100MB.bin for compatibility with the existing Azure Storage test assets.
