The thing is, DSM really holds up well in terms of functionality, stability, and ease of use. When it comes to hardware, Synology is lagging behind, and it’s clearly moving toward a more closed ecosystem. But no other player has quite managed to match Synology’s level when it comes to software. TrueNAS and Unraid are both very solid, but neither is as user-friendly as DSM. HexOS is still in beta, and even after the 1.0 release, it will take time before it reaches feature parity with DSM.
This video mentions a few alternatives, but if QNAP is off the table for you, things start getting tricky.

Ultimately, what you should do really depends on how much effort you're willing to put into switching systems. If you’re not up for that, there’s nothing wrong with paying the "Synology tax" and accepting that you're tied to Synology drives. In return, you get a DSM system that’ll likely serve you well for years.
I’ve had a Synology running in my network for over 15 years, and it just does what it’s supposed to. My most important data still lives on it. Let me be clear: I’m definitely not happy with their recent direction. I think they’ve abandoned part of their user base with flimsy arguments—no 10GbE, Synology-only drives, EOL hardware. That criticism is everywhere on YouTube right now. But on the flip side, no one’s forcing you to buy Synology. If you want the DSM appliance experience and you're okay with Synology’s quirks, it can still be a solid choice.
Personally, I’m very disappointed with Synology’s 2025 releases. I was hoping for a lot more. But if I’m being honest, I wouldn’t rule out buying another Synology in the future. That would be strictly for NAS and backup functionality. I haven’t used DSM for anything else in a long time. I’m really into the vision behind HexOS. It’s a super promising project. But for now, it’s still a system in development, and it’s not yet a replacement for DSM when it comes to storing my most critical data.
At the end of the day, it’s about figuring out what matters most to you. In short: make your own call.
