Synology has messed up again—in a good way—with the new DiskStation DS925+, a 4-bay NAS that's eager to take on the professional market, but without forgetting those of us who like to have a bomb-proof home cloud. It's no simple "disk drawer": it's dressed up like a serious office, but underneath it's a pair of running-ready sneakers.
This new model joins the family Plus, that range of Synology that already has more than one million installations under its belt, and which has proven to be as popular among independent professionals as it is in offices, branches, and techie setups looking to set up a mini data center at home. The DS925+'s proposition is clear: compact, fast, scalable and reliable. Come on, like the ideal work partner.
Compact on the outside, devastating on the inside
Who said size matters? The DS925+ has a discreet and compact appearance, with that signature sober, minimalist design. But the real meat is inside. This NAS is designed to sustain the pull under demanding workloads, and it's not just a marketing phrase: he backs it up with serious specifications.
Turbocharged performance
Carries dual 2.5GbE ports so you don't drown in network traffic, and it also incorporates two M.2 NVMe slots. Here you can mount cache to speed up reads/writes or even create a all-flash volume If you're all about uncompromising speed. Not bad for a device that falls into the "prosumer" category.
According to Synology data, performance has improved significantly compared to its predecessor:
- + 149 % in downloads via SMB
- + 150 % in loads
- + 131 % in reading
- + 150 % in writing
It almost looks like they've put a rocket inside the chassis.
Scalability for when your data keeps growing
Because we all know that "I'll only save what's important" is a white lie. Today you're saving work documents and phone backups, and tomorrow you're setting up a media server with your ripped Blu-ray collection.
That's where the DS925+'s expandability shines: it comes standard with 4 bays, but if that's not enough for you, you can attach the new expansion unit DX525 and reach the 9 bays y 180 TB raw capacity. Yes, you read it right: 180 terabytesThere are no excuses to delete anything ever again.
Reliability is not negotiable

Behind this decision there are more than 7.000 hours of rigorous testing, and a validation policy designed to ensure long-term, sustained performance. Synology makes it clear: this NAS is designed to last, not to scare you.
DSM: The Soul of the NAS
If the hardware is the body, the DiskStation Manager (DSM) It's the brain. And as Synology has accustomed us to, this browser-based interface is a joy.

It's not just for businesses (although it's perfect for them)

And those who want to tinker more?
There's room for geeks here too. DSM allows you to install packages like Docker, to run self-hosted containers and services, or set up a virtual machine with another operating system inside the NAS. If you're into the world of home servers, The DS925+ is a very serious toy with which you can spend hours and hours.
