# NVMe Storage

All DanubeData VPS instances include ultra-fast NVMe SSD storage for optimal performance. This guide covers NVMe features, performance, and best practices.

## Overview

NVMe (Non-Volatile Memory Express) provides:

- **Ultra-Fast**: 3,000+ MB/s sequential reads
- **Low Latency**: Sub-millisecond response times
- **High IOPS**: 100,000+ random read IOPS
- **Included**: Part of every VPS profile
- **Enterprise-Grade**: Reliable, durable storage

## Performance Characteristics

### Sequential Performance

| Operation | Performance |
|-----------|-------------|
| Sequential Read | 3,000+ MB/s |
| Sequential Write | 2,000+ MB/s |

### Random Performance

| Operation | IOPS |
|-----------|------|
| Random Read (4K) | 100,000+ |
| Random Write (4K) | 80,000+ |

### Latency

- **Read**: < 0.1ms
- **Write**: < 0.2ms

## Storage Allocation

NVMe storage included per profile:

**Shared plans:**

| Profile | NVMe Storage |
|---------|--------------|
| Nano | 20 GB |
| Micro | 40 GB |
| Small | 80 GB |
| Medium | 160 GB |
| Large | 320 GB |

**Dedicated plans:**

| Profile | NVMe Storage |
|---------|--------------|
| Nano | 40 GB |
| Micro | 80 GB |
| Small | 160 GB |
| Medium | 320 GB |
| Large | 640 GB |

## Best Practices

### Performance Optimization

1. **Use Modern Filesystem**: ext4 or xfs
2. **Enable TRIM**: Maintain performance
3. **Align Partitions**: Ensure proper alignment
4. **No RAID Needed**: Already redundant

### Monitoring

Monitor storage usage:

```bash
# Check disk usage
df -h

# Check I/O statistics
iostat -x 1

# Monitor real-time I/O
iotop
```
