UGREEN DXP6800 Pro vs DXP8800 Plus

Choose the DXP6800 Pro when your storage plan fits within six SATA drives with room for growth; choose the DXP8800 Plus when you expect to need more drives or want more empty bays at the same starting capacity. UGREEN specifies the same i5-1235U processor, 8GB DDR5 and dual 10GbE for both, so the extra bays are the clearest reason to move up. Keep your four-bay NAS if its capacity and applications still meet your needs and the upgrade would consume your backup budget.

Compare the exact US models

The UGREEN US comparison contains separate entries for these models. Its embedded specifications also identify the US SKUs below; select the complete model name when using the comparison.

Those maximum-storage figures add SATA and M.2 capacity together. They are raw installed totals, not the data capacity of your protected HDD array. The system SSD is listed separately from the M.2 slots; don't count it as another user drive purchase.

Best when six drives cover your growth: DXP6800 Pro

The six-bay model is our default when the capacity worksheet below leaves a comfortable margin. Its processor, installed RAM and Ethernet specification match the eight-bay Plus, so buy it for the storage configuration you need rather than a suffix that sounds more powerful.

A four-drive start leaves two SATA bays empty. A six-drive start fills it. That difference matters if you prefer adding drives later to replacing a complete set with larger ones. Reserve money for the backup destination before optional SSDs or memory.

Best for more drive capacity: DXP8800 Plus

The eight-bay enclosure makes sense when the six-drive plan falls short or would leave no growth margin. With the same four starting disks, it leaves four SATA bays empty; with six installed, it leaves two. Buying the enclosure does not require buying its entire eventual drive set immediately.

UGREEN explicitly labels the US DXP8800 Plus diskless. Its package illustration lists a power adapter, cables, manual, warranty card, cooling strips, screwdriver and screws. Verify the US power cord and exact cable types in the selected package; the illustration's wording does not establish their specifications.

The Plus is a capacity pick. Its existence does not establish faster application performance, quieter operation or a shorter rebuild time.

Start with equal capacity, then count the empty bays

Use matching 8TB drives for this example. According to UGREEN's storage-mode documentation, RAID 5 allocates one drive's capacity to parity and tolerates one member failure; RAID 6 allocates two and tolerates two. RAID 6 requires at least four drives.

The following are our calculations using UGREEN's formulas: RAID 5 = (drive count − 1) × smallest drive; RAID 6 = (drive count − 2) × smallest drive. Capacities are decimal TB before system and filesystem overhead. An empty bay contributes no capacity, and no row includes a hot spare.

• Four installed drives16TB
• Six installed drives32TB
• Eight installed drives48TB

Source: Calculated from UGREEN's RAID 6 formula; see the capacity table and linked storage documentation above.

Our preference for an important archive is RAID 6 plus an independent backup, provided the resulting capacity fits. RAID 5 is an alternative when its extra capacity matters and you accept its lower failure tolerance. Neither choice replaces backup.

Reserve is separate from parity. Add current files, expected growth, application data and retained versions or snapshots, then leave free space beyond that total. The figures above are ceilings, not fill targets. UGREEN's Storage app documentation explains how to set an insufficient-capacity warning; use it before space becomes urgent.

Expansion: empty bays are useful, but check the pool

UGREEN's storage-mode documentation describes adding drives for RAID 5 and RAID 10, and lists RAID 5/6 as expandable modes. It does not establish every add-drive combination for every firmware release. Before buying future disks, confirm that the installed pool offers the required expansion operation; do not treat the capacity table as an instruction to insert several disks together.

For conversion, the current Change RAID Type document applies to UGOS Pro firmware 1.19.1.0126 or later. It lists Basic to RAID 1 or RAID 5, and RAID 1 to RAID 5. It does not list RAID 5 to RAID 6; JBOD and RAID 0 require backup and recreation for conversion. Create RAID 6 at the start if that is your intended protection level.

When all bays are occupied, UGREEN documents replacing every RAID member with a larger drive. Its procedure is disable one drive, power off to replace it, then repair the pool; wait until repair completes and status returns to Normal before the next replacement. Back up first and maintain stable power. This is why extra empty bays can be valuable even before you need their capacity.

Match the network and applications

Both models specify dual 10GbE. UGREEN's network documentation says these series negotiate lower link speeds, including 2.5Gbps and 1Gbps. For a faster wired path, check the computer adapter, intervening switch and cable as a complete chain.

UGREEN advertises aggregated bandwidth of up to 20Gb for the Plus, but explicitly warns that a single 10GbE client should not expect 20GbE transfers. Neither that aggregate nor Thunderbolt's interface bandwidth is measured file throughput. The maker lists drives, RAID, client, switch, cables and file type among transfer constraints.

Thunderbolt direct connection uses the NAS's Thunderbolt IP address and SMB in UGREEN's instructions. It needs a Thunderbolt-capable host and certified cable; an ordinary USB-C connector does not establish compatibility. UGREEN also documents Windows driver requirements. For containers, virtual machines or media applications, check your actual application requirements before treating either chassis as a performance upgrade.

Count the full kit and the independent backup

For the four-drive RAID 6 start, a second NAS with its own four compatible 8TB drives in RAID 6 would match the primary's theoretical data capacity: eight HDDs across two enclosures, before a spare. This is a planning example, not a certified bundle. Allow additional backup capacity for retained versions and the destination's own overhead.

UGREEN distinguishes backup on independent media from RAID and snapshots. A second pool inside the same enclosure is not our independent-backup plan. Keep the older NAS as a possible destination if its usable capacity and backup method fit; define exactly which folders need protection if you cannot back up everything.

The WD Red Plus WD80EFPX is an 8TB planning example, not a verified enclosure/drive bundle. WD describes Red Plus as CMR NAS storage for up to eight bays. Our fetched UGREEN compatibility page did not expose model-specific drive results, so we cannot certify this exact drive for either NAS. Select the exact enclosure and full drive part number before ordering; do the same for RAM and UPS hardware.

For power planning, UGREEN publishes 70.39W during drive access and 28.99W during drive hibernation for the Plus, while warning that installed drives, load and peripherals affect consumption. These are maker operating figures, not a measured full-kit maximum or a UPS runtime guarantee. Include the backup destination and networking in the load worksheet; our UPS guide covers that buying decision.

Check variants before a holiday offer

The US comparison identifies DXP6800 Ultra with a Core 5 120U and DXP8800 Ultra with a Core 7 150U; both have a published memory maximum of 96GB, versus 64GB for the Pro/Plus pair here. They are separate hardware choices. The support documentation also contains DXP8800 Pro naming; do not silently substitute it for US DXP8800 Plus SKU 35126.

• Yes: Match the complete model suffix and US SKU in the comparison table
• Yes: Confirm installed drives, power accessories and cable types in the selected package
• Partly: Verify each exact HDD, RAM and UPS part number against UGREEN's compatibility results
• No: Treating advertised maximum storage as included drives or protected usable capacity

For the DXP6800 Pro, the captured US comparison confirms the SKU and specifications but does not establish its full packing list. Confirm enclosure-only contents and US power accessories before ordering. Compare the complete enclosure, drives, backup, network and power order; an enclosure promotion alone cannot settle that choice.

How we choose

This is a manufacturer-document comparison with no measured transfer, acoustic or rebuild results. We checked UGREEN's US product data, model-specific support documents and compatibility guidance, plus WD's drive specifications. Recommendations prioritize capacity after RAID, empty bays, a documented expansion route and a separate backup. Calculated capacities are labeled; unresolved compatibility and conflicting maker labels remain explicit. See How we choose.

Verdict

Buy the DXP6800 Pro if the six-drive plan comfortably covers your projected data and reserve while leaving funds for backup. Buy the DXP8800 Plus if you need the eight-drive plan or its extra empty bays at an equal-capacity start. Keep a suitable four-bay NAS until you can identify the capacity or application requirement that justifies replacing it.
