What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
ASUSTOR Lockerstor 4 Gen3 (AS6804T)
Only one whitelisted tester (TechRadar) published a hands-on review of this exact model. TechRadar rates it 4/5, praising its AMD Ryzen Embedded V3C14 CPU with ECC DDR5 memory, up to 30GbE of network bandwidth and mature ADM 5.0 software, but flags the steep ~$1,300 price (nearly double the Gen 2), the missing GPU, and M.2 slots limited to a single PCIe lane. (1 sourced review, 1 lab-tested.)
Praised: Powerful AMD Ryzen Embedded V3C14 CPU paired with ECC DDR5 memory; Huge network bandwidth: dual 10GbE plus dual 5GbE and USB 4.0 direct connection; Mature, feature-rich ADM 5.0 software with an excellent app selection.
Flagged: Expensive for a four-bay NAS (~$1,300), nearly double the Gen 2 price; No GPU, which hurts Plex/video transcoding; M.2 slots limited to a single PCIe lane; trays require tools (not tool-less).
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).
