FAQs
Can I expand the RAM in the Synology DS425+?
Yes. The DS425+ comes with 2GB DDR4 RAM and can be expanded up to 6GB by adding one D4NS01-4G SODIMM module. This upgrade can improve multi-user performance and application responsiveness.
What network speeds does the DS425+ support?
The DS425+ features dual network ports: one 1GbE (1 Gigabit Ethernet) and one 2.5GbE (2.5 Gigabit Ethernet). The 2.5GbE connection provides faster data transfer for time-sensitive operations like backups and large file transfers.
Can I use NVMe SSDs for storage in this NAS?
The DS425+ has built-in M.2 2280 NVMe slots, but these are designed for cache acceleration, not primary storage. Storage bays are for 3.5" SATA drives. Using NVMe as a cache layer improves performance without occupying storage bay capacity.
Does the DS425+ support IP camera surveillance?
Yes. The DS425+ can support up to 25 IP cameras with a total of 750 FPS at 720p (H.264). It includes two free camera licenses; additional cameras require purchasing additional licences.
What is Snapshot Replication and why do I need it?
Snapshot Replication is a backup technology that creates point-in-time copies of your data. It enables rapid recovery from data loss, accidental deletion, or ransomware attacks, significantly reducing downtime and protecting business continuity.
Is the Synology DS425+ diskless, and what drives should I use?
Yes, the DS425+ is diskless—drives are not included. Synology recommends Enterprise Series HAT5300 (3.5") HDD, Plus Series HAT3300 (3.5") HDD, or Enterprise Series SAT5200 (2.5") SSD. Always check Synology's compatibility list for approved drives.
What warranty does the DS425+ come with?
The Synology DS425+ includes a 3-year hardware warranty. This can be extended to 5 years with the optional EW201 warranty extension, available for additional purchase.
