UGREEN NASync DXP4800 Plus

UGREEN spent years as a power-accessory brand before jumping into storage in 2024, and the NASync DXP4800 Plus is the clearest statement of intent in that first six-device lineup. It's a four-bay desktop NAS built on a 12th Gen Intel Pentium Gold 8505 — five cores, six threads, integrated graphics with Quick Sync — paired with 8GB of DDR5 and two SO-DIMM slots that take it to 64GB. That's a configuration that looks a lot more like a small-form-factor PC than the anaemic Celeron-and-4GB formula most four-bay boxes have shipped with for years.

The networking is what genuinely sets it apart: a 10GbE port alongside a 2.5GbE port, bondable for failover or extra throughput, and at launch the only model in UGREEN's range mixing two Ethernet speeds. Add two PCIe 4.0 M.2 slots usable as a flash pool or as read/write cache, a proper 128GB SSD for the system disk rather than eMMC-style flash, 4K HDMI out, and a front-panel USB-C/USB-A/SD combo, and you have a machine aimed squarely at content creators offloading cards, home labbers who want to run things locally, and small businesses that have outgrown a single share.

Who's it for? Anyone whose bottleneck is the network rather than the CPU, and anyone comfortable being an early adopter on a platform that hasn't had a decade to mature.

On hardware, this is one of the more convincingly specified four-bay units we've assessed. The Pentium Gold 8505 is a meaningful step up from the Intel Processor N in the standard DXP4800 — more memory headroom, PCIe Gen 4, 20 lanes — and it's the difference between a NAS that just serves files and one that can plausibly host containers, VMs or Quick Sync-accelerated transcoding. DDR5 expandable to 64GB is generous headroom for that kind of work, and the inclusion of Btrfs alongside ext4, full RAID 0/1/5/6/10 and 88TB of raw capacity means the storage fundamentals are not an afterthought. The dedicated SSD system disk and front-mounted SD slot are the kind of details that suggest UGREEN actually talked to photographers and videographers.

The caveats are real, though, and they cluster in two places. First, UGOS Pro. Every review of this machine lands on the same point: it is a young operating system with a smaller native app catalogue and a much shorter track record than Synology's DSM or QNAP's QTS. For a device you trust with irreplaceable data over a five-to-ten year life, platform maturity and update cadence matter as much as silicon, and UGREEN simply hasn't had time to prove either. The 2-year warranty is adequate rather than reassuring in that context.

Second, the 10GbE port is only as good as the rest of your network. Extracting its benefit requires a compatible switch and client NIC, which is an additional and not-trivial cost that prospective buyers should budget for up front. It's a strength of the product, but a conditional one.

A note on pricing: no price was supplied to us, and since the entire value proposition of a NAS like this rests on how it's costed against a comparable Synology or QNAP, we're withholding judgement there. Our rating reflects the hardware and platform on their own merits. On that basis it's a strong, well-equipped machine with one significant asterisk — buy it for the connectivity and the CPU, go in with open eyes about the software.
