💡 Analysis & Recommendations
Hybrid Architecture Analysis:
✅ Advantages on USB SSD:
• Lower hardware performance → Software optimization more impactful
• USB latency higher → Cache benefits more significant
• HDD-like scenario → Hybrid architecture shines
⚠️ Considerations:
• USB SSD still fast (300-500 MB/sec)
• Extra overhead (cache query) still present
• Need real-world workload testing
🎯 Recommendations:
• Test FUSE hot path (repeated file access)
• Test metadata queries (SQL operations)
• Test HDD scenario (150 MB/sec baseline)
• Compare NVMe vs USB vs HDD
Expected Results:
• USB SSD: Hybrid 20-30% faster than Traditional
• HDD: Hybrid 50-100% faster than Traditional
• Network Storage: Hybrid 2-5x faster
