Synology neo+ is a lower-entry-memory version of the 2025 Plus platform. The DS725neo+, DS925neo+, DS1525neo+ and DS1825neo+ keep their matching Plus model's CPU, bays, networking, M.2 and expansion features, but start with 4GB non-ECC DDR4 instead of factory ECC. Buy on regional price and memory needs, not an assumed performance downgrade.
Synology neo+ models compared
| Model | Bays | CPU | Networking | Expansion | Factory memory |
|---|---|---|---|---|---|
| DS725neo+ | 2; 7 with DX525 | Ryzen R1600 | 1 × 2.5GbE | 2 M.2 | 4GB non-ECC |
| DS925neo+ | 4; 9 with DX525 | Ryzen V1500B | 2 × 2.5GbE | 2 M.2 | 4GB non-ECC |
| DS1525neo+ | 5; 15 with 2 × DX525 | Ryzen V1500B | 2 × 2.5GbE; 10GbE option | 2 M.2 cache | 4GB non-ECC |
| DS1825neo+ | 8; 18 with 2 × DX525 | Ryzen V1500B | 2 × 2.5GbE; 10/25GbE option | 2 M.2 cache | 4GB non-ECC |
What neo+ means
Synology announced the family on August 5, 2026 as an accessible starting configuration alongside the regular Plus line. It is not a new DSM tier: backup, Drive, Photos, Surveillance Station and the storage features of the corresponding chassis remain available.
The trade-off is memory protection and, on the five- and eight-bay models, factory capacity. All neo+ models can reach 32GB with supported modules, including listed ECC options, but Synology does not support mixing ECC and non-ECC DIMMs.
Which family fits each buyer
| Use case | Best choice | Why |
|---|---|---|
| Home backup and photos | neo+ if cheaper | Same DSM tools and storage platform; factory ECC is less critical for a modest workload. |
| Plex | Either for direct play | The matching AMD CPUs are identical and lack Intel Quick Sync. |
| Photographer | DS925neo+ / DS1525neo+ | Four or five bays balance capacity, snapshots and growth. |
| Small business | Regular Plus | Factory ECC and, on larger models, 8GB installed reduce setup risk. |
| Heavy containers or VMs | Price the RAM first | Both can reach 32GB; starter memory is not the final configuration. |
neo+ or regular Plus?
Choose neo+
- The price saving is verified in your region
- You are building a home backup or photo NAS
- You plan a deliberate matched memory upgrade
- You do not need factory ECC
Choose regular Plus
- You want ECC from first boot
- The unit stores business-critical data
- The Plus model is the only official local listing
- A neo+ memory upgrade erases the saving
Synology third-party drive policy, as of DSM 7.3
DSM 7.3, released October 8, 2025, lets Synology Plus, Value and J models released in 2025 and later install DSM and create storage pools on third-party hard drives and 2.5-inch SATA SSDs. Synology's policy table names those series and does not list the neo+ line separately; the neo+ models is a Plus-platform model released in 2026, and the hard-drive compatibility list Synology publishes for it contains Synology drives only. Check that list before buying third-party drives for it.
M.2 NVMe is the exception. Creating an M.2 storage pool or an SSD cache on the neo+ models still requires a drive on Synology's compatibility list, and that list contains Synology SNV3400, SNV3410 and SNV5420 drives only.
- Hard drives and 2.5-inch SATA SSDs that are not on Synology's compatibility list: supported for a new installation, for creating a storage pool and for migration. Synology still recommends listed drives.
- M.2 NVMe SSDs that are not on the compatibility list: cannot create a storage pool or an SSD cache. They are accepted only when migrated, already in use, from another Synology system.
- Any drive on Synology's incompatibility list: not supported for installation, storage pools or cache.

Can you buy a neo+ model in the United States?
On October 12, 2026 none of the four neo+ models had a product page on Synology's US site, and none could be bought from a US seller on Amazon.com. Amazon.com carries a DS925neo+ listing that is out of stock with no offer, and a DS725neo+ sold and shipped by Amazon Japan as an import at $818.82. We found no Amazon.com listing for the DS1525neo+ or DS1825neo+.
Synology's announcement said the line would sell through its global channels, but an import from another region carries that region's warranty and power cord, so treat the Japanese listing as an import, not a US launch. The regular Plus model is the one with US availability today.
