UGREEN NASync DXP4800 Plus four-bay NAS review

The NASync DXP4800 Plus is a diskless desktop NAS with four SATA bays, two separate M.2 NVMe positions, and built-in 10GbE plus 2.5GbE. UGREEN's current U.S. product information and model comparison describe a Pentium Gold 8505, 8 GB DDR5 memory, and a listed memory ceiling of 64 GB. This is a documentation-based review of the standalone SKU 35260US, not a hands-on test or a promise about a third-party offer.

Four SATA positions, with M.2 kept separate

Four native SATA trays make the Plus a different scale from a two-bay starter NAS. The model manual has separate drive-installation instructions for 3.5-inch and 2.5-inch devices, while the specifications list two M.2 NVMe slots. Those M.2 connectors are not extra SATA trays. UGREEN describes them for SSD caching, and its 144-TB maximum combines four 32-TB SATA drives with two 8-TB M.2 SSDs. That number is raw installed-capacity arithmetic, not included storage, a single volume, or an amount you should expect from every RAID choice.

The standalone NAS is diskless. UGREEN says data drives are sold separately and directs buyers to a model-specific compatibility reference. Match full drive part numbers and capacities against that list before ordering; a brand name or connector alone does not establish support. Also check whether the actual offer is the base machine or a separately named bundle. UGREEN's product data lists a DXP4800 Plus + UPS3000 option, which is not the standalone SKU reviewed here. Neither the UPS nor any data drive should be inferred from a generic “DXP4800 Plus” offer title.

Two network ports, but one link is the fast path

The model page lists one 10GbE RJ45 port and one separate 2.5GbE RJ45 port. That gives a buyer room to connect a workstation or switch with a 10-gigabit interface while retaining a lower-rate link for another network segment. It does not combine into one 12.5Gbps connection. The link rating also is not expected file-copy speed: the switch or router, client NIC, cabling, drive array, files, and workload all affect the transfer. If 10GbE is the reason to choose the chassis, confirm a compatible port on both ends of the route rather than upgrading only the NAS.

Choose the storage layout before buying drives

UGREEN lists Basic, JBOD, RAID 0, RAID 1, RAID 5, RAID 6, and RAID 10. A buyer-created two-drive RAID 1 arrangement is possible and would leave two of the four trays open, but the machine does not ship with a prepared mirror. UGREEN's RAID guidance describes RAID 1 as requiring at least two drives; exact capacity depends on the smaller member of the pair and on the rest of the storage setup. RAID 5, RAID 6, and RAID 10 have different minimum drive counts and capacity costs, so do not read the 144-TB headline as a useful-capacity promise. A mirror can help with a drive failure, but it is not a second copy against deletion, malware, theft, or enclosure loss.

The two M.2 positions add a separate SSD path; they do not enlarge a SATA RAID group. Before selecting cache or another storage role, check the exact SSD model, capacity, and supported software path. The compatibility reference is model-specific and can change with firmware. Do not assume that a listed memory maximum names a particular upgrade stick: UGREEN asks users to select the exact NAS and module before purchasing.

What the hardware does—and what it cannot promise

The official comparison lists a 5-core/6-thread Intel Pentium Gold 8505, 8 GB of DDR5 and a 64-GB maximum, plus 4K HDMI output and an SD 3.0 card reader. Its listed footprint is about 178 × 178 × 257.5 mm (height × width × depth), so leave space for the chassis and airflow rather than treating it as a tiny router. UGREEN's materials promote media, Docker, and virtual-machine uses, but those capability labels do not establish performance for a particular number of services, users, or transcoding workload. No independent benchmark was used for this assessment.

One source detail is worth checking before setup: the current U.S. product page uses both “UGOS” and “UGOS Pro” in different information sections. That wording does not establish a firmware build or future update policy. Use the exact-model Download Center and instructions for the unit you receive; do not apply an update file intended for a different NAS.

Who should consider it, and the final checks

The DXP4800 Plus is a plausible fit when four internal SATA drives, one 10GbE link, and two distinct M.2 positions solve a real expansion or workflow need. It is less compelling when the buyer needs an all-in-one disk package, a proven sustained transfer rate, or a storage plan whose usable capacity has not been calculated. A 2.5GbE link elsewhere in the path will remain the bottleneck even if the NAS connects at 10GbE.

Before committing, verify the exact standalone SKU 35260US, the contents and warranty route of the seller's package, the drive and memory part numbers in UGREEN's current compatibility list, the intended RAID or pool layout, and the full switch-to-client path. The model page and manual establish a four-bay diskless NAS; they do not establish reseller stock, a seller's included accessories, an initialized volume, or Amazon listing identity. Treat the maker's capacity and speed maxima as conditional specifications, not independent test results.
