NAS watts and dB(A): DS224+ vs DXP2800 vs F2-425 vs AS5402T
Maker lab numbers only. A 24/7 box in a bedroom is a different SKU than a closet next to a GPU workstation.
Same disclaimer as the first-NAS note: we have not burned these units in and we do not have a Labthrift wall-watt log. The table is what the makers published, plus one named third-party measurement on the F2-425. Drive mix changes the number. Treat every watt as “in their lab, with their disks.”
| Box | Access | Hibernation | Sleep / noise | Brick |
|---|---|---|---|---|
| DS224+ | 14.69 W | 4.41 W | 22 dB(A) idle with Synology HDDs, 1 m. Scheduled on/off. | 60 W |
| DXP2800 | 16.38 W | 5.24 W | UGREEN lab, Seagate 2 TB. Quiet mode 29–34 dB on the product page. | — |
| F2-425 | 22 W (Neowin + official comparison table) | 11 W | Official 19.0 dB(A) standby, 2 SATA, 1 m. Neowin used 2× ST4000VN008. | 48 W |
| AS5402T | 22.9 W | 12.7 W | 0.71 W S3. Datasheet table. | 65 W |
| DXP4800 Plus (skip-for-bedroom) | 42.36 W | 18.12 W | Quiet mode 29–34 dB (UGREEN). Already the 10G pick on first-nas.html. | — |
A bedroom first box is the DS224+ if you want scheduled power and the lowest published access watts, or the AS5402T if you will actually use S3. A closet next to a workstation can eat the DXP4800 Plus numbers. Do not put the 10G 4-bay on the nightstand and then complain about 42 W and two fans.
If you are chasing dB, a 5400 / 5640 RPM Red Plus is the quieter spinning class — and it is still the wrong only disk for iSCSI VMs. IronWolf 1–6 TB is 5400; ST8000VN004 is 7200. Skip SMR (EFAX, EZAZ, BarraCuda 3.5" 4 / 8 TB) even if someone sold it as “quiet.”
Diskless paths: DS224+ B0C6927XPX / B&H 1781611-REG. DXP2800 B0D22HBFK1 / UGREEN store $369.99 on 22 Aug 2026. F2-425 $254.99 official, out of stock at fetch. AS5402T B0C5MB5MTS / B&H $369.00 at research fetch.
Skip
Skip treating maker dB(A) as what you will hear with two cheap desktop disks and the fan on high. Skip a 10G 4-bay for a bedroom. Skip inventing a yearly kWh bill from these numbers — we did not measure your utility rate or your spin-down schedule.
