What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
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, 2 lab-tested.)
Praised: Powerful 8-core Intel Core i3-N300 with 32GB DDR5 leaves real headroom for Docker, VMs and multi-user office work; Dual 2.5GbE with link aggregation, plus two M.2 NVMe slots usable as ordinary storage or as cache — not locked to cache duty; 10 Gbit/s USB-A and USB-C ports on the rear (TechRadar specifies USB 3.2 Gen 2).
Flagged: High price — $699 in the US / €729.99 in Europe, a flat $200 more than the vanilla F4-424 and far above the F4-423 predecessor (about €336 at the time); HDMI output is nearly useless — no graphical interface in TOS, only Linux console output; TOS trails Synology's DSM in polish and functionality (TechRadar adds that TeraSync, Centralized Backup, Log Center and Surveillance Manager are all still in Beta; Notebookcheck adds there is no terminal package manager such as yum or apt).
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, 1 lab-tested.)
Praised: Affordable $499 price for a 7-bay mid-size NAS; Balanced, consistent performance across RAID configs (RAID10 strongest); User-friendly UniFi Drive interface with 1GbE and 10GbE connectivity.
Flagged: Limited third-party app ecosystem versus rival NAS platforms.
