About 280 MB/s per 2.5GbE port is the author’s expected ceiling, not a documented measured file transfer. Thunderbolt is discussed as a faster workstation path.
Test setup, measurements & limitations
TechRadar: IceWhale ZimaCube 2 Personal Cloud NAS review
Tested: ZimaCube 2 Standard at $799: Core i3-1215U, 8 GB RAM, 256 GB NVMe, six SATA bays, four M.2, dual 2.5GbE, dual Thunderbolt 4. Affiliate links disclosed.
Applies to: Qualitative Standard review. Spec table mixes useful ports/RAID list with likely gen-1 leftovers (LPDDR5/32 GB, 19 V 11.58 A 220 W, 7.4 kg) that Cube 2 shop/unboxing/STH contradict — those three fields are not used as Cube 2 facts.

- M.2 expansion is the weak link (reviewer describes Gen 3 x1-class per slot). The single PCIe 4.0 slot is the shared answer for 10GbE, faster NVMe, and GPU.Source location: Performance — Limited M.2 / expansion
- Current shop FAQ says ZimaOS Plus is included. The article’s paid Plus upgrade claim conflicts with that primary statement and is not used as an extra purchase cost.Source location: Software / 30-second review
Limits to keep in mind
- Affiliate disclosure.
- Spec table conflicts with Cube 2 shop JSON on memory type/limit and PSU; those cells discarded.
- 280 MB/s is not a captured benchmark chart.
- Mixed-generation memory/PSU and incorrect all-Gen4 lane description discarded; no local-LLM token benchmark.
- The 800 MB/s per-drive wording conflicts with the official shared-bandwidth FAQ and NASCompares array results.
