# MinIO Erasure Code Quickstart Guide [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

MinIO protects data against hardware failures and silent data corruption using erasure code and checksums. With the highest level of redundancy, you may lose up to half (N/2) of the total drives and still be able to recover the data.

## What is Erasure Code?

     *
     * <p>Since the last element of the array is actually in the middle of the sorted structure, a
     * childless aunt node could be smaller, which would corrupt the invariant if this element
     * becomes the new parent of the aunt node. In that case, we first switch the last element with
     * its aunt node, before returning.
