- **MinIO creates erasure-coding sets of _2_ to _16_ drives per set.  The number of drives you provide in total must be a multiple of one of those numbers.**
- **MinIO chooses the largest EC set size which divides into the total number of drives or total number of nodes given - making sure to keep the uniform distribution i.e each node participates equal number of drives per set**.
- **Each object is written to a single EC set, and therefore is spread over no more than 16 drives.**

- Less than `STANDARD` Parity, if it is set.

Default value for `REDUCED_REDUNDANCY` storage class is `1`.

### Set storage class

The format to set storage class environment variables is as follows

`MINIO_STORAGE_CLASS_STANDARD=EC:parity`
`MINIO_STORAGE_CLASS_RRS=EC:parity`
