This guide covers storage types, features, and best practices.\n\n## Overview\n\nStorage options include:\n\n- **NVMe SSD Storage**: Ultra-fast NVMe storage included with all instances\n- **Block Storage**: Additional persistent storage volumes\n- **Snapshots**: Point-in-time backups of volumes and instances\n- **Database Storage**: Managed database storage with automatic scaling\n- **Backup Storage**: Long-term backup storage\n\n## Storage Types\n\n### NVMe SSD Storage\n\nIncluded with all VPS instances:\n\n- **Performance**: Up to 3,000+ MB/s read, 2,000+ MB/s write\n- **IOPS**: 100,000+ random read IOPS\n- **Latency**: Sub-millisecond latency\n- **Reliability**: Enterprise-grade NVMe SSDs\n- **Included**: Part of instance profile\n\n**Learn More**: [NVMe Storage Documentation](https://docs.danubedata.ro/storage-nvme)\n\n### Block Storage\n\nAdditional persistent volumes — the productized **Volumes** feature:\n\n- **Capacity**: 10–500 GB per volume\n- **Performance**: network-attached SSD storage\n- **Flexibility**: Attach/detach from instances\n- **Snapshots**: Create point-in-time backups\n- **Scaling**: Resize volumes without downtime\n\n**Learn More**: [Volumes Documentation](https://docs.danubedata.ro/volumes)\n\n### Snapshots\n\nBackup volumes and instances:\n\n- **Full Backups**: Complete volume/instance copies\n- **Incremental**: Only changed data after first snapshot\n- **Instant Recovery**: Restore in minutes\n- **Retention**: Keep snapshots as long as needed\n\n**Learn More**: [Snapshots Documentation](https://docs.danubedata.ro/storage-snapshots)\n\n## Storage Performance\n\n### NVMe Performance\n\nTypical performance metrics:\n\n| Metric | Value |\n|--------|-------|\n| Sequential Read | 3,000+ MB/s |\n| Sequential Write | 2,000+ MB/s |\n| Random Read IOPS | 100,000+ |\n| Random Write IOPS | 80,000+ |\n| Latency | < 1ms |\n\n### Block Storage Performance\n\nVolumes are network-attached, with throughput up to ~1 Gbps. For the highest IOPS, use the local NVMe on your VPS root disk.\n\n## Storage Pricing\n\n### Included Storage\n\n- VPS instances include SSD storage in profile\n- Database instances include storage in profile\n- Cache instances include persistence storage\n\n### Additional Storage\n\n**Block Storage (Volumes)**:\n- €0.04/GB/month\n- Billed hourly\n\n**Snapshots**:\n- €0.073/GB/month\n- Incremental storage only\n\n## Best Practices\n\n### Storage Management\n\n1. **Right-Size Volumes**: Start small, scale as needed\n2. **Regular Snapshots**: Backup important data\n3. **Monitor Usage**: Track storage consumption\n4. **Clean Up**: Delete unused volumes and snapshots\n5. **Use Block Storage**: For data that needs to persist independently\n\n### Performance Optimization\n\n1. **Use NVMe**: Fastest performance for OS and applications\n2. **Separate Data**: Use block storage for data volumes\n3. **RAID Not Needed**: Storage already redundant\n4. **Filesystem Tuning**: Use ext4 or xfs for best performance\n5. **Monitor IOPS**: Ensure not hitting limits\n\n### Data Protection\n\n1. **Regular Backups**: Automate snapshot creation\n2. **Test Restores**: Verify backups work\n3. **Multiple Copies**: Export important snapshots for offsite copies\n4. **Encryption**: Enable encryption for sensitive data\n5. **Access Control**: Limit who can delete volumes\n\n## Related Documentation\n\n- [Block Storage](https://docs.danubedata.ro/storage-block)\n- [NVMe Storage](https://docs.danubedata.ro/storage-nvme)\n- [Snapshots](https://docs.danubedata.ro/storage-snapshots)\n- [VPS Managing](https://docs.danubedata.ro/vps-managing)\n- [Database Backups](https://docs.danubedata.ro/databases-backups)\n\n","prev":{"title":"Custom Domains & DNS","slug":"custom-domains","url":"https://docs.danubedata.ro/custom-domains","markdown_url":"https://docs.danubedata.ro/custom-domains.md","json_url":"https://docs.danubedata.ro/custom-domains.json"},"next":{"title":"Object Storage (S3)","slug":"object-storage","url":"https://docs.danubedata.ro/object-storage","markdown_url":"https://docs.danubedata.ro/object-storage.md","json_url":"https://docs.danubedata.ro/object-storage.json"},"index_url":"https://docs.danubedata.ro/index.json"}
