UGreen or Synology???

[billykris2528]

Hi, I would like to ask your recommendation in buying NAS.
I’m completely new with NAS storage system and doesn’t have any experience in IT fields, so I can say I’m completely blind with all these things  

I currently use Google Drive & Youtube to store my work-related files. 
Now I’m considering to buy UGreen DXP4800 Plus or Synology DS925+

Primarily, I would like to use NAS to:
1. Store my work related things so I can access it anywhere across different devices
2. Allow my team to access work related files anywhere through a shared link (without the need to create account for them), just like a simple link sharing in google drive.
3. Backing up photos & videos from my iphone so I can have more capacity in my phone.
4. Storing & securing my client’s personal data from breach, but I still can access them when I need to.
5. Using Plex/Jellyfin application to store training videos & allowing my team to access it like netflix (but with training video) anywhere & anytime by sharing link (like youtube) -> is it possible?

Please give me insight on those two 4-bay NAS.
And is it possible for a NAS to handle those 5 things?

Thanks in advance.

Short Answer: Go with the Synology DS925+

Here's why:

For Your 5 Requirements:

Remote access - Both can do this, but Synology's QuickConnect makes it dead simple. No port forwarding knowledge needed.

Link sharing without accounts - This is where Synology shines. Their File Station lets you create share links exactly like Google Drive. UGreen's UGOS Pro is improving, but it's not as polished yet for this workflow.

iPhone backup - Synology Photos has excellent iOS integration with automatic upload. Works brilliantly. UGreen can do this too, but the app experience isn't as refined.

Client data security - Synology has mature encryption, 2FA, and granular permissions. They've been doing this for 15+ years. UGreen is newer to the enterprise security game.

Plex/Jellyfin for training videos - YES, absolutely possible! Both NAS can run these. However, Synology also has Video Station as a native alternative that might be simpler for your team access needs.

The Reality Check:

The DXP4800 Plus has better hardware specs and costs less - that's tempting. But for someone without IT experience, Synology's DSM operating system is significantly more user-friendly. Their documentation, community support, and mobile apps are years ahead.

UGreen is great value and improving fast, but you'll hit more "how do I do this?" moments. With your workflow (team sharing, client data, remote access), you want something that just works.

My Recommendation: DS925+ with 2x 4TB drives in RAID 1 to start (mirrored for protection). You can add more drives as you grow.
