Pi 4 vs Pi 5 NAS Battle: 60x Faster? Shocking Benchmark Results

I tested my new Pi 5 NAS against my Pi 4 NAS with comprehensive benchmarks. The results? Absolutely shocking. The Pi 5 is 13x faster for sequential writes and 60x faster under mixed workload. Let me show you the data.

*The Results:*
• Sequential writes: 13.3x faster on Pi 5 (3.6 MB/s → 47.9 MB/s)
• Mixed workload: 60x faster on Pi 5 (21 IOPS → 1,168 IOPS)
• Random 4K operations: 4-5x faster
• Consistency: Pi 5 delivers perfect repeatability vs Pi 4's variability

*Fair Testing:*
• Same 4x 2TB SSDs tested in both systems
• Same RAID 10 configuration
• Same gigabit network
• Multiple test runs for accuracy
• Industry-standard tools (fio, iperf3)

*The Bottom Line:*
If you're building a new NAS, get the Pi 5. If you have a Pi 4 and it's struggling, the upgrade is absolutely worth it. The performance differences aren't incremental - they're transformational.
