UGREEN NASync vs Synology

UGREEN is the phone-charger and dock company that walked into the NAS market in 2024 with the NASync series, and the hardware is genuinely good. Synology has been building NAS boxes for two decades and its software shows it. If you line the two up spec for spec at the same price, UGREEN wins the hardware fight by a wide margin. If you line them up feature for feature in the OS, Synology wins the software fight almost as decisively. Your decision is really about which of those two things you value more for the job you have.

The wrinkle in 2026 is that Synology made its own case harder. Its 2025 Plus-series models restrict some storage features to Synology's own branded drives, which raises the real cost and annoys anyone who wanted to bring their own disks. That single policy is why a lot of people who would have bought Synology on autopilot are now actually reading a comparison like this one. For the mature-appliance side of the argument, it is worth reading QNAP vs Synology and Synology vs TrueNAS alongside this.

Take the two direct competitors. UGREEN's DXP4800 Plus runs an Intel Pentium Gold 8505, a five-core chip with an integrated GPU, ships with 8GB of DDR5 that you can take to 64GB, and gives you two M.2 NVMe slots and dual 2.5GbE. Synology's 4-bay Plus boxes run AMD Ryzen chips (the R1600 in the DS923+, the V1500B in the 2025 DS925+) with 4GB of ECC DDR4, no integrated graphics, and, on the DS923+, still only gigabit networking unless you add a 10GbE card. For the same money, or less, UGREEN gives you more cores, more and faster memory, and faster networking out of the box.

The integrated GPU is the part that actually changes what the box can do. Intel Quick Sync means the UGREEN can hardware-transcode video for Plex or Jellyfin, so it can reshape a 4K stream for a weak client without pinning the CPU. Synology dropped Intel iGPUs from its Plus line, so the current AMD-based models do software transcoding only, which is slow and limited. If a media server is anywhere in your plan, that gap is decisive. It is the same transcoding question that decides Jellyfin vs Plex, except here it is baked into the silicon.

The other quiet advantage is memory and cache headroom. DDR5 to 64GB and two NVMe slots means the UGREEN has room to run a stack of Docker containers, a couple of VMs, and an NVMe read cache without feeling starved. Synology's 4GB ECC baseline and 32GB ceiling are fine for a file server and light apps, and ECC is a real plus for data integrity, but the ceiling is lower and you feel it faster once you start piling services on.

DSM is the best NAS operating system on the market, and it is not particularly close either. It is stable, the interface is coherent, and the first-party apps are the real draw. Active Backup for Business backs up Windows machines, servers, and VMware or Hyper-V hosts for free with no per-agent license, and it is excellent. Surveillance Station is a capable NVR with two free camera licenses. Synology Photos and Synology Drive cover the Google Photos and Dropbox replacement itch cleanly. Btrfs with scheduled snapshots and Snapshot Replication is built in and reliable. When something breaks, twenty years of forum threads and a large community mean the answer already exists somewhere.

UGOS Pro, UGREEN's operating system, launched in 2024 and is improving quickly, but it is a toddler next to DSM. You get a clean file manager, a Photos app with on-device AI recognition, backup and sync tools, an App Center, Docker, and virtual machine support, which covers the basics well. What you do not get is a decade of polish or anything close to Active Backup for Business or Surveillance Station in maturity. The community is small, so when you hit an edge case you are often the first person writing about it. For a NAS you expect to run untouched for years, the newness of the software is a real, not theoretical, risk.

There is also the trust question, because it comes up in every UGREEN thread. UGREEN is new to storage and new to shipping an operating system that holds your data and, in most homes, faces the internet in some way. Its update cadence so far has been good, but it does not have Synology's track record on security response. If that bothers you, the answer is not to talk yourself into it. It is the third option below.

On Synology's 2025 Plus-series models, creating a storage pool and getting full drive health monitoring, deduplication, and firmware updates now expects Synology-branded (or explicitly certified) drives. Put a plain WD Red or Seagate IronWolf in one of those bays and you get warnings and reduced functionality, where the same drive worked fine on a 2023 model. Synology-branded drives are rebadged and carry a premium, so this raises the true cost of a new Synology and takes away the flexibility of shopping for whatever NAS drive is on sale that week.

This matters more than it first looks, because the drives are usually the bigger line item than the box. If you are filling four bays with 8TB or larger disks, a per-drive premium adds up fast, and it recurs every time you expand or replace a disk. UGREEN puts no such restriction on you: buy whatever reputable SATA or NVMe drives you like, and plan the array in a RAID calculator without a brand tax on the shopping list. If you specifically want to stay with Synology, the way around the policy is to buy a pre-2025 model like the DS923+, which still takes third-party drives freely.

Because the NASync boxes are standard x86 machines, you are not stuck with UGOS Pro. You can wipe it and install TrueNAS Scale, Unraid, or even Proxmox, which turns the UGREEN into a bare-metal host for whatever storage OS you actually trust. That is the escape hatch for the software-maturity and trust concerns: you keep the strong Intel hardware and the Quick Sync iGPU, and you run an operating system with a long track record and a big community. Synology gives you no equivalent option, since DSM is locked to Synology hardware.

This is the route I would point most tinkerers toward. Pair a DXP4800 Plus with TrueNAS Scale for a ZFS-first build, or with Unraid if you want mixed drive sizes and simple app management, and you get better hardware than Synology sells at that price with an OS that will still be supported and documented in five years. If you go this way, read TrueNAS vs Unraid to pick the OS and skim the best NAS operating systems roundup first. The catch is honesty about effort: this is a build-it-yourself project, not the plug-in-and-forget experience that makes Synology worth its premium for a lot of people.
