## What reviewers say

**TerraMaster F4-424 Pro** — Two whitelisted hands-on reviews of this exact model, both from its early-2024 launch window. Both call the 8-core i3-N300 with 32GB DDR5 genuinely powerful for Docker, VMs and multi-user work, and both flag the high price ($699 / €730) and the near-useless HDMI output, which shows only Linux console text because TOS has no graphical interface. Measured throughput is network-bound: Notebookcheck recorded 210 MB/s write and 296 MB/s read, TechRadar puts the ceiling at around 280MB/s over a single 2.5GbE port. Only Notebookcheck published power and noise figures (23.8 watts idle, 33.7 dB idle). (2 sourced reviews.)

**Ubiquiti UniFi UNAS Pro** — StorageReview is the only whitelisted outlet with a hands-on lab review of the exact 7-bay Ubiquiti UNAS Pro. Their CrystalDiskMark testing over a 10GbE link across RAID 5/6/10 praised the $499 price and consistent, balanced RAID10 throughput but flagged a limited third-party app ecosystem versus rival NAS platforms. (1 sourced review.)
