Best Practices
Performance Optimization
- Use Modern Filesystem: ext4 or xfs
- Enable TRIM: Maintain performance
- Align Partitions: Ensure proper alignment
- 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
