Ugreen is China, Synology is Taiwan. Something to consider if you're concerned with the privacy of your data.

I have both Synology and Ugreen. If you're going to use the included OS, Synology is the better option. If you're willing to install a different system like TrueNAS or unRAID, go with some other option than Synology. My ugreen unit has been great.

Community Reviews

Synology's 4 bay DiskStation stands out for its polished DSM software, strong backup tools, and solid performance for home storage, Plex, and photo libraries. The DS925 plus brings more RAM headroom, dual 2.5 gigabit Ethernet, faster read and write speeds, and expansion support, while the DS425 plus is attractive for Plex because its Intel Celeron has Quick Sync. The main cautions are Synology's drive and SSD compatibility restrictions, higher total cost once RAM and disks are added, and the fact that the DS925 plus lacks a GPU for transcoding. It is a capable platform, but the value depends heavily on the workload and storage budget.

  • home users who want a big upgrade from an older Synology NAS for everyday file sharing and backups because one commenter said the DS925+ has been "working great" and was a "huge upgrade" from their DS213j.

    CitraNinja

  • people setting up a NAS for photos/videos and basic home file sharing (with optional VPN) who aren't planning to run Plex, Docker, or VMs because one commenter said for that kind of basic use the DS425+ "might be sufficient" and could save about $100 versus the DS925+.

    t588t588

  • Plex users who need hardware transcoding for remote access or slower connections because commenters specifically pointed out the Intel Celeron model's Intel Quick Sync and PlexPass hardware transcoding as a "massive speed increase" for serving content to remote people or bad playback devices.

    dclive

  • buyers who want more network throughput on a 2.5GbE setup because the DS925+ has two 2.5GbE ports (vs the DS425+ having one 2.5GbE plus one 1GbE), which commenters said can matter for SMB multi-channel throughput.

    pilot757

  • people who want to start with a small number of drives and expand later for NVR/Plex because one commenter described starting with 2 drives using mirror sync (no RAID) for access if a drive dies, then adding drives later for additional uses like NVR and Plex.

    Ride_The_Sky

  • buyers who plan to use third-party SSDs for caching/flash because commenters warned that Synology requires Synology-branded M.2 SSDs for caching/flash (and that third-party NVMe SSDs can't be used for caches or storage pools).

    eyeslickimtrusty

  • buyers who are unwilling to deal with Synology's drive/compatibility restrictions (or the extra cost of Synology RAM/SSDs) because multiple commenters said Synology restricts drive compatibility to branded drives and that you'll pay more for RAM and Synology NVMe SSDs.

    LavenderPickle7682imtrusty

  • people who want to use Plex/Jellyfin/Emby hardware transcoding on the DS425+ without workarounds because a commenter said DSM 7.2+ disabled kernel graphics drivers (i915.ko) and that blocks those apps from accessing hardware transcoding.

    MadPup

  • people who need a NAS for critical files without a solid 3-2-1 backup plan because a veteran commenter said this 4-bay Synology is "good for Raid5 (4 drives)" but "not recommended for critical files without a 3-2-1 backup," and warned not to depend on a 4-drive Synology without backup.

    ElatedBorder615

  • people who want to avoid any compromise on speed/reliability when accessing data outside the house because one commenter said if you access data outside your home, it "isn't going to be as fast or reliable" as Google/Apple cloud.

I upgraded to 4x26TB for my DS920+. I need to sell my 4x 14tb. Any suggestions?
Are they NAS drives? If so will you sell just 2 for a reasonable price?

I have seen Seagate IronWolf Pro 12 TB (7200 RPM) at $280 as well. Sucks what has happened to PC parts prices.
Jesus, you aren't kidding. The HD prices are what's stopping me so far from upgrading my old DS916+ to something like a UGreen running TrueNAS or building a DIY NAS. I have 3 Seagate Ironwolf Pro 16TB drives in my DS916+ that I bought for $199 each around BF of 2023. I went to look at current prices and almost blacked out.

The Celeron has Quick Sync so it's good for transcoding. I don't know if the Ryzen has any hardware transcoding.
Didn't Synology nerf Quick Sync on the 425+? There are workarounds, but it's not native.

4 drive NAS is also good for Raid 1 and Raid 10
I specifically mentioned mirror and striped mirror in the first paragraph. Most think 4 bay NAS and don't want to take the hit on space using a mirorr. Do you not know what mirror means?

However, this four-bay NAS only comes with one multi-gig LAN port, and if you want to utilize M.2 SSDs for caching or flash storage, you must use Synology-branded ones. If you require more high-speed connectivity options and the ability to use third-party M.2 SSDs, our top pick for four-bay NAS devices, the Asustor Lockerstor 4 Gen 3 (AS6804T), is a better—albeit more expensive—choice.

i've loved synology for awhile and was looking for a replacement, but recent posts shows they're getitng more anti-consumer by the day - is it just me?

it feels like they don't care about the regular people who helped make them popular in the first place. first, they were going to hard lock their drives[1], get rid of video station[2], and now pushing more monthly subscriptions.

the OS is great, but i don't want to risk having my data hoarding stuff potentially held hostage. i'm thinking UGREEN, but how far is it off from DSM?

Synology lock hard drive is too exacerbated. They did the same with memory but gradually expanding their compatibility memory list. Video Station is dead for a while since it didn't support 4k and no longer retrieve meta from online media database. Ugreen OS is still inferior to Synology in term of open OS for third party applications. The aggressive Ugreen are pushing for many high end products make a lot of doubt about their motivation.

Ugh! What a shitty move.

"The DS425+ uses an Intel Celeron J4125 processor with integrated Quick Sync Video support, capable of H.264 and HEVC transcoding in hardware. However, Synology deliberately disabled the kernel graphics drivers (i915.ko) in DSM 7.2+ updates, blocking apps like Plex, Jellyfin, and Emby from accessing it."

This! Their "No third party hard drives" decision that they then had to walk back after sales plummeted was nothing more than a cash grab that blew up in their face. Damage has been done. For the money, I would rather buy a Ugreen or any of the many other units out there now and run Xpenology (DSM straight rip off) or TrueNAS, etc. on the device.
Interesting, I didn't realize they stopped enforcing that requirement. I bought a Qnap instead during the holidays for that very reason. I had a couple 14TB WD shucked drives and was waiting on a NAS sale. Oh well, they lost my business because of their greed.

Is this pretty much the lowest it goes?
yeah, it's lowest price, but you will pay more on RAM, and their own synology nvme ssd. you cannot use 3rd party nvme ssd for caches or storage pool.

Long gone are the days when a second-hand Toshiba 12TB server HDD was sold for $75. Neither a NAS nor a HDD purchase right now is considered a good investment unless I desperately need more storage. Good thing is that this has forced me to take time to rescan all old files on my three TerraMaster NAS and deleted 10+ TB worthless data (Windows 7 ISOs, outdated driver installation files for my retired PCs, etc.)

Be careful. Synology has restricted their drive compatibility list so that you can only use their branded drives. And they weren't cheap before the price increases. Now? Who knows.

The price difference between the DS425+ and DS925+ is about $100, and I understand that the DS925+ is the more capable unit. For basic home use — such as backing up photos and videos from phones and cameras, file sharing and backups for home PCs, and possibly using VPN for remote access — it sounds like the DS425+ might be sufficient. I won't be using Plex (or would use another player to handle decoding), and I won't be running any Docker containers or VMs.Given this use case, is the DS425+ good enough? It would be great to save the extra $100 for disks if the performance difference isn't worth it for my situation.
You'll be all in for $1,000-$1,500+ with either plus disks. IMHO, spend the extra $100 up front so this stays relevant for twice as long (double the ram, double the speed).
