Specifications
Pros & Cons
👍 Pros
- Dedicated NPU enables on-device AI processing for surveillance and image recognition without cloud dependency
- Six drive bays offer substantial raw storage capacity in a single desktop unit
- PCIe Gen 3 x2 expansion slot allows adding faster networking or M.2 SSD caching
- Triple network ports (one 2.5GbE plus two 1GbE) provide flexible connectivity and link aggregation options
- Dual 4K HDMI outputs let you connect surveillance monitors or media displays directly
👎 Cons
- 8GB RAM is soldered and cannot be upgraded, which may limit demanding multitasking workloads
- Ships diskless, so the total cost of ownership rises significantly once drives are purchased
- ARM-based processor is less powerful than x86 alternatives for general-purpose NAS applications
- HDMI 1.4b output caps at 4K 30Hz rather than the 60Hz supported by HDMI 2.0
- Only a single PCIe expansion slot limits how many add-on cards you can install
