UGREEN NASync DH2300 + UPS3000 bundle review

The NASync DH2300 + UPS3000 pairs UGREEN's two-bay home NAS with its larger US3000 DC battery accessory. That can be a tidy first NAS package for a home that wants a local shared folder or photo destination and a dedicated power buffer for the NAS. It is not a populated storage kit, and it is not a small rack UPS for the whole network. Most of the actual NAS decision is unchanged from the standalone DH2300; the extra item is the only reason to choose this exact package over that base model.

Identify the UPS variant before comparing bundles

The U.S. product data names the exact selected configuration “UGREEN NASync DH2300 + UPS3000,” variant 45922508996802 and combined manufacturer SKU 95087+45615. UGREEN's page lists the package components as a DH2300 and UPS3000 with 12,000mAh and 120W; it separately says the data drives are not included. The UPS accessory page identifies that component as US3000, with a maximum 120W output, 12,000mAh battery, rated 43.2Wh, zero-second transfer and USB data communication. UGREEN's UPS guide explicitly lists the DH2300 as compatible with US3000.

UGREEN also presents a separate DH2300 + UPS2000 selection. This review is about the UPS3000 variant only; “DH2300 + UPS” is not a complete enough description to verify the contents of a retailer offer. Check the exact suffix and component SKU on the seller's page. The larger accessory's wattage and battery rating are not an independently verified promise of how long a populated NAS will run. UGREEN says its approximate runtime depends on NAS, drives, workload, battery condition and shutdown settings. Set up the USB communication and safe-shutdown policy, then test it with your actual equipment.

Two bays leave little room for a wrong storage plan

The NAS itself is a compact, diskless two-SATA-bay system with one built-in 1GbE RJ45 port, 4GB LPDDR4X memory, Rockchip A72+A53 eight-core processing, HDMI output specified for 4K/60Hz, and no M.2 positions. The 64TB figure on UGREEN's page means two separately purchased 32TB drives at raw capacity, not included or formatted storage. In a possible two-drive RAID 1 setup, both trays are occupied; UGREEN describes about 32TB before formatting with two 32TB drives. Check the exact part numbers and firmware compatibility before buying. The cited U.S. page does not establish an approved memory upgrade, and UGREEN says the DH2300 does not have official Docker or virtual-machine support.

That makes it a more focused appliance than a small general-purpose server. It can fit a basic home-file or photo-backup role where the supported applications, one-gigabit wired link and two bays are enough. It is less appealing if you expect to expand the drive count later, install virtual machines, use official Docker support or move a large working set through a faster-than-gigabit network. HDMI is a listed output, not a promise that every codec, streaming app or conversion workload will behave as needed. Decide on the client devices and software workflow before treating “home media” claims as a match for your specific library.

What a DC UPS protects—and what remains exposed

The US3000 is a dedicated DC unit for a compatible NAS power path, with the NAS communicating its state over USB. Follow the exact setup sequence and use the original NAS power adapter where the maker instructs. The DC unit does not add drive redundancy, improve the DH2300's 1GbE ceiling, create a backup copy or automatically power an Ethernet switch and router. If the NAS depends on the router for remote access or on the switch for communication, keep those network devices on their own suitable battery-backed supply. The NAS should still have an independent data backup even when it has both RAID 1 and a UPS.

Who should pay for this specific configuration?

Compare the bundle when the two-bay DH2300 is already the right scale and you want the US3000 included rather than sourcing it separately. The standalone DH2300 is a more sensible comparison if you already own a tested compatible UPS or prefer an AC unit that can cover several devices. If your priority is a four-bay mirror with room for growth, compare a four-bay model such as the DH4300 Plus instead of expecting an accessory to solve the DH2300's bay limit.

Before checkout, confirm the selected variant is 95087+45615 and that the actual package includes the US3000; do not confuse it with the standalone SKU 95087 or the distinct UPS2000 package. Confirm drives are sold separately, validate your exact drive models, plan how to back up beyond RAID, and decide whether your router and switch also need battery power. After delivery, check that the received unit is recognized in UGOS and test the chosen shutdown settings safely. No personal use, outage test, runtime measurement or seller-package inspection is claimed. The review is a comparison of UGREEN's published model and package evidence, not a report from operating the kit.
