# 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?

- **SMB 3.1.1**: Windows 10/Server 2016+ (0x0311) - AES-128-GCM + Pre-Auth Integrity

**Protocol Selection:**
- Default Range: SMB1 to SMB 3.1.1
- Automatic Negotiation: Client offers all supported dialects, server selects highest common version
- Configurable: Min/max versions can be set via configuration properties

### SMB3 Encryption Support
- **SMB2 Transform Header**: Encrypted message wrapping
