Pros & Cons
👍 Pros
- Ships as a complete bundle with six 8TB IronWolf drives, eliminating compatibility guesswork.
- AMD Ryzen quad-core processor handles demanding tasks like virtualization, surveillance, and file indexing.
- Four Gigabit LAN ports with Link Aggregation support provide high aggregate throughput.
- Expandable to 16 bays with two DX517 units for long-term scalability.
- Two M.2 NVMe slots for SSD caching without sacrificing any of the six main drive bays.
👎 Cons
- Base configuration includes only 4GB of RAM, which may require upgrading for heavy multitasking or virtual machine workloads.
- Does not include 10GbE networking out of the box — requires an optional PCIe adapter.
- Six-bay chassis is physically larger than smaller desktop NAS units, requiring dedicated shelf or rack space.
- Fan noise under sustained load can be noticeable in quiet office environments.
- IronWolf drives in this bundle are CMR but top out at 8TB per disk, limiting per-bay density.
