Synology DS425+
The Synology DS425+ NAS serves as a central data storage solution for both home and business environments. The device accommodates up to four hard drives or SSDs, and also supports the installation of two fast M.2 NVMe drives to speed up the system. The integrated Intel Celeron J4125 processor and 2GB of DDR4 RAM ensure the smooth operation of the DiskStation Manager operating system. Users can take advantage of a fast network connection with speeds of up to 2.5Gb/s for instant file transfers. The device supports various RAID array types to protect data against hardware failure.
Key features of the Synology DS425+ NAS
- Four drive bays with a total capacity of up to 80TB
- Integrated 2.5GbE network interface port
- Two motherboard slots for fast M.2 NVMe drives
- Quad-core Intel Celeron J4125 processor
- 2GB DDR4 RAM, expandable to 6GB
- Camera system supports up to 40 IP cameras simultaneously
Fast network interface
The device has two network ports, one of which supports the 2.5GbE standard for fast data transfers on your local network. It delivers a sequential read speed of 278MB/s and a write speed of 281Mb/s. This means users can transfer large volumes of data without unnecessary delays during their daily work. The network interface supports Wake-on-LAN for remote power-up when needed.
Capacity expansion options
The four main bays can be fitted with 3.5" and 2.5" SATA hard drives or fast SSDs. Two additional M.2 NVMe slots are used to set up an SSD cache, which speeds up system response times for repeated file access. The basic 2GB of RAM can be expanded to a total of 6GB DDR4. This gives users enough performance to run more demanding applications and databases.
Efficient backups
The DiskStation Manager operating system includes tools for backing up computers, mobile phones, and cloud services. The system supports the creation of immutable snapshots, which protect stored data from unauthorised tampering or ransomware attacks. Users can set up automatic backup schedules to remote locations or external drives. In the event of a disaster, data recovery is fast and precise, based on the selected versions.
Professional camera system
The storage unit serves as a central hub for monitoring premises with the Surveillance Station application. You can connect up to 40 IP cameras from over 8700 supported models. The system supports dual recording to the cloud in case of physical damage to the local server. Camera management is handled via a clear web interface or mobile app.
Data synchronisation and private cloud
The device facilitates collaboration between branches through automatic one-way or two-way synchronisation between servers. Data can also be synchronised with public cloud providers such as Google Drive, Dropbox, or Microsoft OneDrive. Users share files via secure links with configurable access permissions. Your own private cloud solution maintains full control over sensitive company information.
Virtualisation and management
The model is certified for operation in virtualised environments. Network administrators can use the Central Management System tool to manage multiple Synology servers from a single console. The Active Insight service monitors the overall status of all devices in real time via a cloud interface. This ensures system maintenance and updates are carried out efficiently and without operational downtime.
