Considerations / Limitations

Performance may vary: Real‑world 10 GbE throughput depends on clients, cables, and disk performance.
Software limitations: Some users report that the built‑in TOS OS may be less mature than more mature NAS OS solutions (e.g., TrueNAS, Synology DSM).
Memory expandability variability: Some units are more limited than others, depending on vendor configuration.
