Ugreen NASync DXP8800 Ultra Review: 10GbE Windows Server NAS, 96GB RAM and iSCSI Limits

The latest hardware evaluation from Dave Mitchell at IT Pro puts the flagship 8-bay Ugreen NASync DXP8800 Ultra through its paces. Aimed squarely at growing businesses, creative studios, and Windows power users, this desktop behemoth swaps out the processor of its predecessor, raises the memory ceiling to 96GB, and leans into containerized artificial intelligence.

Does a faster mobile chip and a maturing operating system make this the ultimate desktop storage server for a Windows environment, or are you better off saving upwards of $400 on last year's model? Let’s pop the magnetic dust cover off this beast and examine the facts.

Under the Hood: Changing the Engine, Keeping the Chassis​

If the DXP8800 Ultra looks familiar, that is because Ugreen didn’t fix what wasn’t broken. As TechRadar’s review of the unit aptly noted, Ugreen "changed the engine, not the car". The Ultra uses the exact same dark, rigid aluminum chassis as the older DXP8800 Plus, complete with eight tool-free telescopic drive carriers, an internal 250W power supply, and a rear magnetic dust filter shielding two whisper-quiet 12cm cooling fans.

What changed inside is the silicon driving the bus. Ugreen retired the 12th-generation Intel Core i5-1235U found in the Plus model and dropped in a modern Intel Core 7 150U mobile processor. Here is how the two 8-bay siblings stack up according to Ugreen's official product specifications and IT Pro's testing:

The Core 7 150U brings two multi-threaded performance cores and eight efficient cores to the table, boosting up to 5.4GHz while sipping power at a 15W base TDP. Just as importantly for virtualization and container junkies, the architectural bump increases the maximum DDR5 memory ceiling by 50%, jumping from 64GB on the Plus to 96GB on the Ultra.

Flip the chassis over, release a spring-loaded door on the base, and you get direct access to the two SODIMM slots (one populated with an 8GB stick of DDR5—listed as 5,600MHz in IT Pro's test unit and 4,800MHz on Ugreen's product page) alongside two PCIe 4.0 M.2 NVMe slots for high-speed storage pools or read/write caching. There is also a PCIe Gen4 x4 expansion slot tucked in the rear, though IT Pro warns that while the manual’s instructions are clear, physically reaching and populating that slot requires saintly patience.

Note for rack and shelf planners: There is a slight discrepancy in reported physical dimensions. IT Pro’s spec table lists the chassis at 365 × 272 × 198mm, whereas Ugreen’s official documentation lists 365 × 258 × 189mm (14.4 × 10.2 × 7.4 inches). If you are fitting this into a tight server cabinet, leave an extra centimeter of breathing room.

Section Summary: The DXP8800 Ultra retains the rock-solid aluminum build, dual 10GbE ports, and dual Thunderbolt 4 connectivity of the Plus model, focusing its hardware upgrade entirely on a faster 5.4GHz Intel Core 7 150U CPU and a 96GB RAM limit.

Windows Server 2025 Benchmarks: 10GbE, SMB, and iSCSI Reality Checks​

Specs on a glossy webpage are one thing; pushing terabytes of data across a Windows network is where storage appliances earn their keep. In IT Pro’s lab testing, the DXP8800 Ultra was loaded with four 4TB Seagate IronWolf NAS hard drives configured in a Btrfs RAID 5 array, hooked up to a Zyxel XMG1930-30HP multi-Gig switch, and mapped over a 10GbE link to a Dell PowerEdge host running Windows Server 2025.

Because Ugreen added 9,000-byte Jumbo Frame support to its UGOS operating system earlier this year, raw synthetic throughput over the wire was impressive:

• Iometer Sequential Read / Write: 9.2 Gbits/sec and 8.8 Gbits/sec.
• Iometer Random Read / Write: 9.2 Gbits/sec and 0.7 Gbits/sec.

Of course, synthetic benchmarks mostly prove that the network card and RAM buffer are awake. When copying actual files to and from the Windows Server 2025 host, mechanical hard drive physics re-entered the chat:

• Real-World 25GB Single File Copy: Sustained 3.8 Gbits/sec read and 3.0 Gbits/sec write.
• Small-File Torture Test (22.4GB folder with 10,500 files): Averaged a very solid 2.0 Gbits/sec write speed.

The NVMe Cache Multiplier and SAN Limitations​

Where the DXP8800 Ultra really flexed its muscles was when IT Pro populated those bottom M.2 slots with a pair of Kingston NVMe SSDs configured as a mirrored read/write cache. In random write operations—historically the Achilles' heel of parity RAID arrays like RAID 5—the NVMe cache boosted NAS share speeds by 245% and iSCSI LUN speeds by a massive 290%.

However, Windows administrators planning to use the DXP8800 Ultra as a back-end SAN for Hyper-V or Windows Server failover clusters need to read the fine print. While a 500GB iSCSI target created in Ugreen’s SAN Manager matched the SMB share's raw speeds and supports clustering (allowing multiple clients to connect to the same LUN), IT Pro revealed two significant enterprise omissions:

1. No MPIO Support: Multipath I/O (MPIO) for redundant, load-balanced iSCSI links across those dual 10GbE ports is currently not supported.
2. No iSCSI Snapshots: While choosing a Btrfs volume unlocks storage quotas and snapshots, the snapshot engine currently only protects standard NAS shares, leaving iSCSI LUNs out in the cold.

Section Summary: Over 10GbE to a Windows Server 2025 host, the DXP8800 Ultra delivers standout file-transfer speeds and massive random-write gains when paired with NVMe caching, but the lack of MPIO and iSCSI LUN snapshots limits its appeal as a mission-critical virtualization SAN.

UGOS, Docker 29.6.2, and the Local AI Push​

Hardware has never been Ugreen’s problem; software maturity has always been the main battlefield against entrenched veterans like Synology and Qnap. Ugreen’s Linux-based UGOS is getting sharper, offering a clean web console that guides admins through RAID selection (supporting JBOD, Basic, and RAID 0, 1, 5, 6, and 10), folder setup, and encrypted remote access via a Ugreenlink ID.

Currently, the UGOS App Center offers 35 applications for the DXP8800 Ultra. That is still a smaller catalog than Qnap or Synology, though the essentials for a Windows-centric office are present:

• Desktop & Cloud Sync: Dedicated Windows and macOS desktop client tools run real-time sync tasks to shared folders, while the Cloud Drives app syncs with ten cloud providers, including Microsoft OneDrive, Google Drive, and Dropbox.
• Sync & Backup: Handles local-to-remote Ugreen replication and standard Rsync server jobs.
• Quirky HDMI Playback: Despite sporting an 8K-capable HDMI 2.1 port wired to the CPU’s Intel Iris Xe 96EU graphics, you cannot use it as a local desktop console. It only activates when you open the Theatre app inside Ugreen’s mobile app and project a video stream via "HDMI Play" mode.

The AI Angle: What You Get (and What You Don't)​

Ugreen is heavily marketing AI capabilities across its portfolio, so buyers need to know exactly where the lines are drawn. Ugreen’s standalone AI Console, Uliya, and Voice Memos apps are restricted exclusively to its iDX series appliances and do not run on the DXP8800 Ultra.

Instead, the DXP8800 Ultra gets the Model Manager app, which acts as a control hub for authorizing local AI models inside two specific packages: the Photos app (enabling local people, text, and object recognition) and the Surveillance Center app (powering facial recognition and general detection).

For power users who want true agentic AI, UGOS includes the OpenClaw agent app running atop Docker. Notably, the latest UGOS release updates its underlying Docker Engine to version 29.6.2—a critical July 2026 release from Docker that patches multiple security vulnerabilities. Having a patched, modern Docker engine coupled with a 10-core Intel CPU and up to 96GB of DDR5 RAM means whatever missing business apps aren't in Ugreen's 35-app store can easily be spun up in containers.

Section Summary: UGOS covers core Windows file syncing, OneDrive integration, and local AI photo/surveillance indexing while updating its Docker Engine to 29.6.2 for secure container and OpenClaw deployments—even if native app counts still trail Synology and Qnap.

The Verdict: Should You Buy the Ultra, the Plus, or a Competitor?​

At a diskless price of $1,779.99 on Ugreen’s official US storefront (and quoted at $1,799 in IT Pro's review), the NASync DXP8800 Ultra sits in serious prosumer and SMB territory.

Its closest rival in the traditional NAS space, as highlighted by IT Pro, is Qnap’s TX-h966TX, a 9-bay hybrid appliance that brings dual Thunderbolt 4 ports and support for four U.2 PCIe NVMe SSDs, but steps down to a 6-core Intel Core i3 processor and only a single 10GbE network port. If dual 10GbE links and a 10-core CPU matter to your workflow, Ugreen wins the spec-sheet battle hands down.

The real competition actually comes from inside Ugreen’s own house. With the older DXP8800 Plus frequently selling for $1,369.99 diskless—roughly $410 less than the Ultra—buyers have a clear fork in the road:

• Buy the DXP8800 Plus if your primary workload is straight SMB file sharing, media streaming, and automated Windows PC backups. You get the exact same 272TB capacity ceiling, dual 10GbE ports, and dual Thunderbolt 4 ports for significantly less cash.
• Buy the DXP8800 Ultra if you plan to treat your NAS like a compact edge server. If you are loading up OpenClaw agents, running heavy Docker stacks, hosting virtual machines, and planning to ditch the base 8GB RAM stick for a 64GB or 96GB DDR5 kit, the faster 5.4GHz Core 7 150U processor and expanded memory ceiling will earn back that price premium over a multi-year deployment.
