Asustor AS5404T review: 4-bay, dual 2.5GbE, four M.2
Same N5105 board as the 2-bay, plus RAID 5 / 6 / 10 and a hot spare. Not Synology 1GbE. Not UGREEN 10G.
Nimbustor 4 Gen2. Official datasheet: Intel Celeron N5105, 4 GB DDR4-2933 (max 16 GB, 8 GB × 2), four 2.5" / 3.5" SATA, four M.2 2280 NVMe, dual 2.5GbE, three USB 3.2 Gen 2, HDMI 2.0b. 170 × 174 × 230 mm, 2.26 kg. 90 W brick. 3-year warranty. Volume types: Single, JBOD, RAID 0 / 1 / 5 / 6 / 10, RAID 1 / 5 + hot spare.
Power table: 38.3 W operation, 17.7 W hibernation, 0.81 W S3. That is the 4-bay tax versus the AS5402T 22.9 / 12.7 / 0.71 W. Still an S3 story. Still maker lab numbers. We have not measured wall watts.
The job this box is for: a few VMs on NVMe, media and backups on CMR HDD, 2.5G to a closet switch. ADM App Central and virtualization are real; they are not DSM. If the restore is the product, DS423+ is still the Plus 4-bay — and still gigabit. If you want 10G and Docker as a first-NAS pick, that remains the DXP4800 Plus slot. If you want 32 GB and an x86 board people re-image, F4-424 Pro.
CMR in the SATA bays. Skip WD Red EFAX, Blue EZAZ, BarraCuda 3.5" 4 / 8 TB SMR. IronWolf 1–6 TB is 5400 RPM; ST8000VN004 8 TB is 7200. WD Red Plus WD80EFPX is CMR and 5640 RPM — backups yes, VM LUN no, unless the VMs live on M.2. Guide: 2026 CMR picks.

Skip
Skip if you only need two bays — the 2-bay sibling is the same NIC and M.2 story for less power. Skip if you need 10G. Skip SMR. Skip filling four bays with 5400 RPM disks and calling it a hypervisor datastore.
