Quick Advice: If you don’t plan to use virtualization and are looking for a cost-effective solution, the Intel Celeron-based QNAP TS-864eU could be the right choice. However, for more demanding workloads, consider comparing the CPU benchmark ratings. The QNAP TS-855eU, with its Intel Atom® C5125 CPU and higher benchmark rating, may be a better fit for such scenarios.

Ultimately, the decision should align with your specific workflow and performance expectations. These models offer different combinations of CPU power, RAM capacity, and expansion options, catering to a variety of NAS requirements. Make sure to assess your needs thoroughly before making your selection.
