UGREEN NASync DH4300 Plus review

The DH4300 Plus is a four-bay SATA NAS from UGREEN. It ships diskless, so you supply the drives. It runs UGOS Pro on a Rockchip RK3588 with eight cores, a mix of Cortex-A76 and A55. Memory is 8GB of LPDDR4X, and it is fixed. There is one 2.5GbE port. Those specifications point to a file server with a few containers rather than a virtualisation box.

The four bays take SATA drives. UGREEN gives a maximum of 128TB, from four 32TB drives. The Gadgeteer review gives 120TB, from four 30TB drives. The gap is small, but check the drive size you plan to buy against both figures.

There are no M.2 slots, so there is no NVMe cache or pool inside the chassis. There is also no PCIe expansion. The front panel has one USB-C port and two USB-A ports. With four bays and no M.2, all the capacity sits on the SATA drives you install.

The RK3588 has eight cores, split between Cortex-A76 and Cortex-A55 designs. That is enough core count to run file sharing and a modest set of containers. For media work, UGREEN's buying guide says the model lacks Intel Quick Sync. No other hardware transcoding feature is listed, and no transcoding figures are given. If you stream media that needs transcoding, confirm how it will be handled before you buy.

Memory is the clearest limit. The 8GB is fixed and cannot be expanded, and owners raise this as a complaint. The NAS supports Docker but does not support virtual machines. With fixed 8GB and containers only, it suits a handful of lightweight services. If your workload grows, the memory cannot grow with it.

There is a single 2.5GbE RJ45 port. No second network port is listed. Everything you move on or off the NAS goes over that one connection.

The NAS runs UGOS Pro, UGREEN's operating system. Docker support gives you a route to software that the built-in app list does not cover. Owners do report a limited number of easily installable apps, so expect to lean on containers for anything beyond the basics. No update history is given for the platform, so you have no track record to judge it by.

Owner feedback is split cleanly. Low power consumption and quiet operation get praise. The complaints are the fixed 8GB of RAM and the small selection of easily installed apps. Both complaints match the specifications: the memory is fixed at 8GB and not expandable, and the app library is described as limited.

This is a NAS for backups, shared folders and a few Docker services in a space where noise and electricity use matter. It works for buyers who are content with one 2.5GbE port and who do not need to grow the memory later. It is a weaker choice for virtual machines, NVMe caching, Intel Quick Sync or any plan that depends on adding a PCIe card.
