Should you buy UGREEN NASync or Synology in 2026? Choose UGREEN NASync (such as the 4-bay DXP4800 Plus or 2-bay DXP2800) if you want modern Intel processors with QuickSync hardware video transcoding, built-in 2.5GbE and 10GbE Ethernet, an aluminum chassis, and unrestricted support for third-party NVMe SSDs like the Samsung 990 PRO 2TB. Choose Synology (DS923+ or DS423+) if turnkey DSM 7.2 software, SHR mixed-capacity drive arrays, and native cloud backup suites outweigh raw hardware specs.
| Ecosystem / Component | Processor & Transcoding | Built-In Network Ports | Operating System & RAID | NVMe SSD Policy | Best For |
|---|---|---|---|---|---|
| UGREEN NASync (DXP2800 / DXP4800 Plus) | Intel N100 / Pentium Gold 8505 with QuickSync iGPU | Dual 2.5GbE (DXP4800 Plus adds 10GbE) | UGOS Pro (or bootable TrueNAS / Unraid) | Open third-party M.2 NVMe cache and storage pools | Plex/Jellyfin 4K transcoding, Docker, and multi-gig LAN |
| Synology Plus (DS423+ / DS923+) | Intel Celeron J4125 (DS423+) or AMD Ryzen R1600 (DS923+, no iGPU) | Dual 1GbE (DS923+ supports optional 10GbE module) | Synology DSM 7.2 with Synology Hybrid RAID (SHR) | Storage pools officially locked to Synology-branded NVMe | Turnkey office backups, mixed drive sizes, and non-technical users |
| Samsung 990 PRO 2TB (NVMe Pick) | Samsung Pascal controller with 2 GB LPDDR4 DRAM | PCIe 4.0 x4 M.2 2280 | Works as UGOS Pro NVMe pool or read/write cache | Up to 1,200 TBW endurance rating | Fast Docker appdata, Immich thumbnails, and SMB cache |
| TP-Link Archer BE550 (2.5GbE Router Pick) | Tri-Band Wi-Fi 7 + multi-gig wired backplane | 1x 2.5GbE WAN + 4x 2.5GbE LAN | Standard web UI + EasyMesh | N/A | Eliminating the 115 MB/s 1GbE bottleneck to your NAS |
As a research-based hardware publication without an in-house lab bench, we evaluate NAS enclosures, NVMe cache drives, and multi-gig routers by comparing manufacturer engineering datasheets, PCIe lane allocations, network switch backplanes, and independent storage endurance data from TechPowerUp and StorageReview.
UGREEN NASync enclosures include 2.5GbE or 10GbE Ethernet ports, DDR5 or upgradable DDR4 memory, milled aluminum bodies, and Intel processors with QuickSync video engines as standard equipment. Comparable Synology Plus models still ship with 1GbE ports and older CPUs unless you purchase proprietary add-in network cards.
In addition, UGREEN leaves the BIOS unlocked on its Intel-based models so advanced users can boot TrueNAS Scale, Unraid, or Proxmox from an internal SSD while keeping the stock UGOS Pro system drive intact.
Synology DSM 7.2 remains the gold standard for non-technical households and small offices because Synology Hybrid RAID (SHR) lets you combine different hard drive capacities without wasting space, and packages like Active Backup for Business, Hyper Backup, and Synology Drive work reliably out of the box.
If you do not want to maintain Docker Compose files for photo backups or workstation image recovery, Synology’s software polish saves hours of administration time despite its slower 1GbE default networking.
UGREEN NASync officially supports third-party M.2 2280 NVMe SSDs like the Samsung 990 PRO 2TB and WD_BLACK SN850X for both read/write caching and dedicated all-flash storage pools. Synology DSM 7.2 allows third-party NVMe drives for cache, but restricts native M.2 storage volumes to Synology-branded SSDs without command-line scripts.
Yes, connecting a 2.5GbE NAS to a standard 1GbE router caps your file transfer speeds at roughly 115 MB/s. Upgrading to a multi-gig router such as the TP-Link Archer BE550, which includes five 2.5GbE ports, increases real-world SMB transfer speeds to around 280 MB/s over standard Cat5e or Cat6 cables.
Yes, UGREEN NASync models use Intel processors with integrated QuickSync media engines that support hardware-accelerated 4K HEVC and AV1 transcoding in Plex and Jellyfin. Storing your Docker containers and Immich database on an internal Samsung 990 PRO NVMe pool makes thumbnail scrolling and local AI facial recognition near-instantaneous.
