What to compare closely
This table starts with model specifications. Choose a configuration to compare included memory, storage and captured prices. Adding a PC keeps your selection in a shareable comparison.
- The K8 Plus lists two USB4 ports and two 2.5GbE ports; the UM880 Plus lists one USB4 port and one 2.5GbE port. Match these counts to the dock and network layout you intend to use.
- The UM880 Plus OCuLink adapter occupies a shared M.2 slot. The K8 Plus lists an OCuLink connector alongside two M.2 slots; check enclosure compatibility before planning external graphics.
- Both offer a 32GB RAM and 1TB SSD package as well as a barebone. Select equivalent included capacities before using the displayed US price snapshots to compare purchase cost.
