When it comes to choosing the right short-depth rack mount NAS from QNAP, it’s essential to consider your specific requirements and use cases. In this article, we’ll compare three popular models: the QNAP TS-873AeU-RP, TS-864eU, and TS-855eU, to help you make an informed decision.
Here’s a detailed comparison of their specifications:
| Specification | QNAP TS-873AeU-RP | QNAP TS-864eU | QNAP TS-855eU |
|---|---|---|---|
| Bays | 8 | 8 | 8 |
| CPU | AMD Ryzen™ Embedded V1500B | Intel® Celeron® N5095 | Intel® Atom® C5125 |
| Benchmark | 4584 | 4036 | 8631 |
| RAM | 4 GB UDIMM DDR4 (expandable) | 4 GB SO-DIMM DDR4 (expandable) | 8 GB non-ECC SODIMM DDR4 (expandable) |
| NVMe Slots | 2 x M.2 2280 (PCIe Gen3 x 1) | Not specified | 2 x M.2 2280 (PCIe Gen3 x 4) |
| PCIe Slots | 1 x PCIe Gen3 x8 | Slot 1: PCIe Gen 3 x2 | 2 x PCIe Gen3 (x4) |

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.
