Synology DS925+ Deals Canada – Prime Big Deal Days 2026
By Ryan Fournier · Data checked by Owen Nakamura · Updated Prices checked
The DS925+ launched with Synology's drive lock, and DSM 7.3 relaxed it: third-party hard drives now work for new storage pools, so a cheaper non-Synology drive set is part of the deal maths here, while NVMe still has to come from Synology's list.

Questions about Synology DS925+ deals
Do I need Synology HAT drives in a DS925+?
No, since DSM 7.3 third-party hard drives and 2.5-inch SATA SSDs can create new storage pools. Synology's own drives remain the supported choice.
What NVMe drives can it use?
Only drives on Synology's list, such as its own SNV models, for both cache and storage pools.
Who sells the DS925+ on Amazon.ca?
The seller column names it at each price check. When it reads Amazon US, the unit ships from the United States through Amazon.ca, priced in CAD.
Does the DS925+ need ECC memory?
Yes, it ships with ECC memory and takes up to 32GB.
