TerraMaster F4-425 review: 4-bay x86 and 2.5GbE without NVMe

Four bays at the price of a 2-bay Plus. Same N5095 as the F2-425. Still one 2.5GbE. Still no M.2.

This is the “start with two disks, add later” chassis. Official specification: Intel Celeron N5095 (not the Newegg “N95” row), 4 GB DDR4 non-ECC, one slot, official max 16 GB, four SATA bays, one 2.5GbE, HDMI, no M.2, TRAID / TRAID+, RAID 0 / 1 / 5 / 6 / 10, 90 W brick, 21.0 dB(A) standby claim (2 SATA, 1 m). 222 × 179 × 154 mm, 2.1 kg net. One 120 mm fan. 2-year warranty. Max raw on the store page: 120 TB (30 TB × 4).

Same CPU-label caution as the F2-425: official marketing and the spec block say N5095. Newegg spec blocks have said N95. Quote the official store. Aging Jasper Lake, no NVMe — say that before you celebrate the bay count.

TOS vs DSM is the real comparison, not the NIC. Four empty bays and TRAID are why this exists. If you need snapshots-that-restore and a package list that has been boring for a decade, DS423+ is still the DSM 4-bay. If you want four M.2 and dual 2.5GbE, that is AS5404T. If you want 32 GB and a board people re-image, F4-424 Pro.

Disks: CMR in any RAID / TRAID / ZFS. Skip WD Red EFAX, Blue EZAZ, BarraCuda 3.5" 4 / 8 TB SMR. IronWolf 1–6 TB is 5400 RPM; 8 TB ST8000VN004 is 7200. WD Red Plus 8 TB WD80EFPX is CMR and 5640 RPM — fine for media and backups, wrong as the only VM LUN.

Skip

Skip if you need NVMe or dual LAN. Skip if TOS is the thing you do not want to debug. Skip SMR in TRAID. Skip a used DS918+ as the “real” 4-bay alternative — we dropped that SKU.
