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

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
