Installing the NVMe and Wi-Fi Card
The Opi 6 board includes two M.2 2280 NVMe slots and an M.2 2230 Key E slot for installing a Wi-Fi/Bluetooth card. In our setup, we installed an XrayDisk 1TB Pro PCIe Gen3 X4 NVMe drive. If you are running low on NVMe storage and intend to use the device as a NAS, you can connect an external HDD to one of the two available USB 3.0 ports on the board. In this less-than-ideal configuration, we used basic wire-type antennas, which should deliver decent performance.

Fio Benchmarking
This test measures true sequential read throughput from the NVMe device, bypassing Linux caching. It tells you the real maximum read speed your SBC’s PCIe link and NVMe controller can sustain.

Key Benchmark Metrics
| Metric | Measured Value | Notes |
| Sequential Read Throughput | ~2,724 MiB/s (~2,856 MB/s) | Exceptionally stable across the 18+ second capture period |
| IOPS | ~2,724 IOPS | Expected for large 1MB block transfers ($2724 \text{ MiB/s} \approx 2724 \text{ IOPS} \times 1\text{ MiB}$) |
Average Latency (clat) | ~5.81 ms (5,816 $\mu$s) | Typical completion latency for 1MB transfers at QD16 |
| p90 / p99 Latency | ~8.85 ms / ~13.17 ms | Tight distribution with very few high-tail outliers |
Disk Utilization (util) | ~90.5% | Drive is running near maximum interface/controller capability. |
| CPU Overhead | ~15.7% total (14.9% sys, 0.8% usr) | Extremely efficient IO via io_uring kernel submission |
Analysis & Key Takeaways
- PCIe Bus Bottleneck: The throughput peaking precisely around 2,850 MB/s strongly indicates a PCIe 3.0 x4 interface boundary (or a PCIe 4.0 x2 lane configuration). The controller is fully saturated and delivers the maximum achievable real-world payload bandwidth for this link speed.
- Workload Optimization: Using 1024KiB blocks at Queue Depth 16 allows
io_uringto keep the NVMe controller pipeline completely filled while keeping host CPU utilization minimal (~15%). - Latency Profile: 73.2% of all completed I/O requests landed between the 4ms to 10ms window, which is extremely consistent for 1MB block sizes without severe tail-latency spikes (p99.99 caps at ~17.7ms).

Analysis & Key Takeaways
- Sustained NAND Write Limits: Achieving ~2,339 MB/s continuous sequential write over 65.4 GiB written shows strong flash write performance. This speed is typical for direct TLC NAND execution or high-capacity SLC caching before thermal or cache exhaustion throttling hits.
- Tight Bandwidth Deviation: Throughput stayed tightly bound between 2,122 MiB/s and 2,270 MiB/s with a standard deviation of only 20.79 MiB/s, indicating no active thermal throttling or controller stalling occurred during the 30-second window.
- Latency Uniformity: 98.59% of all write completions fell cleanly into the 4ms–10ms window, demonstrating solid queue management under sustained high-throughput write saturation.

Analysis & Key Takeaways
- Read/Write Ratio Alignment: The workload successfully maintained the target ~70/30 split (~70% read throughput at 974 MiB/s vs. ~30% write throughput at 418 MiB/s).
- Block Size Scaling: Switching from 1MB blocks to 64KB blocks increased overall transaction frequency to ~22.3k total IOPS while reducing read latency from ~5.8ms down to ~2.01ms.
- Asymmetric Write Latency: Write completion latency (
clatavg of 75.5 microseconds) is dramatically lower than read latency (2.01 milliseconds). This indicates the NVMe controller is immediately committing incoming writes directly into its high-speed DRAM cache / SLC buffer, while read operations require physical flash NAND cell lookups. - Disk Headroom: Overall drive utilization measured at 80.25%, showing that while the controller is working hard, it is not completely saturated under this mixed queue structure.

Analysis & Key Takeaways
- Zero SLC Cache Failure / Thermal Throttling: Maintaining an average ~2,213 MiB/s across 648 GiB written in 5 minutes indicates that either the drive uses a massive dynamic SLC cache allocation that didn’t exhaust, or its direct-to-TLC raw NAND write performance is natively capable of holding ~2.2 GiB/s sustained without falling back to a slow folding state.
- Stable Bandwidth Range: Across 599 time-series samples over 300 seconds, standard deviation remained low (23.20 MiB/s). The minimum bandwidth dip stayed at 1,948 MiB/s, showing no mid-run controller lockups or aggressive thermal step-downs.
- Controlled Latency Spectrum: 98.68% of writes completed cleanly between 4ms and 10ms, nearly matching the shorter 30-second run (98.59%). Maximum latency actually decreased from 34.5ms (Test 2) to 19.8ms (p99.99), demonstrating remarkable controller stability under prolonged thermal load.

Key Technical Conclusions
- Interface Saturation: Sequential reads peaked at 2,724 MiB/s (~2,856 MB/s), saturating the physical PCIe 3.0 x4 bus limits.
- Sustained NAND Integrity: In Test 4, writing 648 GiB continuously over 5 minutes resulted in a minimal 0.7% throughput delta (2,213 MiB/s vs. 2,230 MiB/s in 30s), proving the drive does not suffer from thermal throttling or severe cache exhaustion under high-volume transfers.
- Queue & Controller Optimization: The
io_uringengine kept host CPU overhead low (~13–18% sys) while keeping 98%+ of completion latencies tightly bounded under 10 ms across all queue depth configurations.
