The data displayed on storj.io is the free capacity estimation and is coming from https://stats.storjshare.io/data.json

**"storage_free_capacity_estimate_bytes"** attribute.

We get the maximum value across satellites and convert it to Petabytes.

`6004403070856310`

bytes to Petabytes **~ 5.3Pb** (current value on storj.io at the time I write this response)

We do use a conservative approach to calculate **storage_free_capacity_estimate_bytes** since it is an estimation we do calculations based on the actual free disk distribution removing the extremes.

We also offer the **median** value in the same endpoint: **"median_available_bytes"**

Iâ€™ll ask to replace â€śCapacityâ€ť with â€śFree Capacityâ€ť on the storj.io homepage to avoid confusion.
