Synology DiskStation neo+: what you give up for the lower price
Synology has quietly added NEO versions of four Plus NAS models. Same processor and bays, but less memory and no ECC on the bigger ones. Is it a bargain or a trap?

While most of the NAS world waits for Synology's next-generation DiskStation, the company has added a cheaper tier to its current range. The DS725neo+, DS925neo+, DS1525neo+ and DS1825neo+ appeared on product pages and distributor listings in August 2026 without a launch event, and Synology did not mention them at Computex in June.
The difference in one table
| Model | Standard Plus memory | neo+ memory |
|---|---|---|
| DS725+ / DS725neo+ | 4 GB ECC | 4 GB non-ECC |
| DS925+ / DS925neo+ | 4 GB ECC | 4 GB non-ECC |
| DS1525+ / DS1525neo+ | 8 GB ECC | 4 GB non-ECC |
| DS1825+ / DS1825neo+ | 8 GB ECC | 4 GB non-ECC |
The neo+ models keep the same processors, drive bays, networking and three-year warranty as their Plus equivalents. Synology's own page for the DS925neo+ lists four bays, two 2.5GbE ports, expansion to nine drives and built-in M.2 NVMe slots. In other words, this is a cost-reduced version of an existing machine, not a new generation.
Does ECC matter at home?
ECC memory detects and corrects single-bit errors. For a NAS holding family photos, a home server with a few containers, or a backup target, the real-world risk of a memory error is low, and many popular home NAS products have never offered ECC. But it is a genuine reliability feature, and it is the thing the bigger neo+ models lose, along with half their RAM. Four gigabytes is tight if you intend to run Docker containers, Synology Photos with face recognition and a VM together.
Who should consider a neo+
- Simple file storage and backups: a DS725neo+ or DS925neo+ is likely enough.
- Plex or Jellyfin with 4K transcoding, many containers, VMs: the processors in this range are several years old and the memory is limited. Look at the standard Plus range or at a different platform altogether.
- Anyone who values data integrity first: pay the extra for ECC.
The wider picture
Two other things are worth knowing. DSM 7.3 reversed the 2025 restriction that tied volumes to Synology-branded drives, so Seagate IronWolf and WD Red disks are accepted again. M.2 NVMe pools and caches, however, are still limited to Synology-branded SSDs apart from a narrow migration exception. And DSM 7.4 was released on 16 June 2026.
My advice: compare live UK prices for the neo+ against the Plus model, and against any older Plus stock still on shelves, since those often include ECC and more memory for a similar price. If the saving is under about £40, take the Plus.
