The Synology DiskStation DS225+ is a desktop NAS server of the Home & Home Office category, designed for central storage, management, and backup of data. The device features two drive bays for 8,9 cm ( 3,5 inch )- or 6,3 cm ( 2,5 inch )-SATA hard drives and is delivered without pre-installed drives. It is based on the Synology DiskStation Manager (DSM) operating system, which enables central management of files, applications, and backup functions. The platform is suitable for use in private households, small offices, or for managing surveillance cameras, with integrated support for cloud backups and central management of multiple Synology devices simplifying system control.

Applications

The DS225+ is designed for use in home applications and small work environments. It serves as a central storage solution for documents, images, videos, and other files. The integrated support for video surveillance enables management of surveillance cameras, with data stored on internal drives. The platform is also suitable for backing up local devices and applications, with cloud backup functions available. Central management of multiple Synology devices supports usage in small networks.

Functions and Equipment in Detail

The device features an Intel® Celeron® J4125 processor with a clock speed of 2 GHz, responsible for processing file operations, network connections, and applications. The integrated memory capacity is 2 GB DDR4 RAM, with additional memory available via a free RAM slot, up to a maximum of 6 GB. The hardware supports RAID-0, RAID-1, and JBOD modes to optimize performance, redundancy, or total drive capacity. The hard drives must be SATA-compatible, with sources specifying that only Synology hard drives are supported to ensure reliability and consistent performance.

Technology Explained Simply

The DS225+ uses an active cooling system to stabilize internal components under load. Network connection is via two RJ-45 ports: one 2.5 GbE and one 1 GbE port, enabling fast data transfer within the local network. Storage is via SATA technology, with drives mounted directly in the device. Management is performed via the DSM operating system, accessible through a web interface, enabling configuration of users, shares, backups, and applications.

Compatibility and Accessories

The platform is compatible with SATA 8,9 cm ( 3,5 inch )- and 6,3 cm ( 2,5 inch )-hard drives. Sources emphasize that only Synology hard drives are supported to ensure optimal reliability and system stability. The use of other hard drives is not explicitly confirmed. Network connection is via the two RJ-45 ports, with the 2.5 GbE interface providing higher transfer rates. The two USB-3.0 ports enable connection of external storage devices or printers.

Installation and Mounting

Installation involves mounting the hard drives in the two bays, with SATA cabling and power supply handled by the integrated power supply. System configuration is performed via the web interface of the DSM operating system, accessible through a browser. Setup includes selecting the RAID mode, configuring users and shares, and activating backup functions. Management of multiple devices is performed via the central DSM interface.

Advantages in Operation

The DS225+ offers a central storage solution with high reliability through support for RAID modes. The integrated video surveillance function enables management of surveillance cameras, with data stored locally. Cloud backup functions provide additional backup options. Central management of multiple Synology devices simplifies system control. The 2.5 GbE network interface ensures fast data transfer within the local network. RAM expandability up to 6 GB allows adaptation to growing requirements.

Hard Drive Compatibility

The use of other hard drives is not explicitly confirmed, so compatibility with non-Synology drives is not guaranteed. The hard drives must be SATA-compatible, with sizes of either 8,9 cm ( 3,5 inch ) or 6,3 cm ( 2,5 inch ).

Operating System and Software

The device runs on the Synology DiskStation Manager (DSM), a proprietary operating system controlled via a web interface. DSM enables management of files, users, shares, backups, and applications. The software supports management of video surveillance cameras, cloud backups, and central control of multiple Synology devices. The software is designed for managing small networks and offers a user interface accessible via a standard web browser.

Network and Interface Connections

The DS225+ features two RJ-45 network ports: one 2.5 GbE and one 1 GbE port, used for connecting to the local network. The two USB-3.0 ports enable connection of external storage devices or printers. Network connection is via Ethernet, with the 2.5 GbE interface enabling higher transfer rates. Power supply is via the integrated power supply, with PoE (Power over Ethernet) not supported.

Expandability and Scalability

RAM capacity is expandable, with one free RAM slot available. Maximum memory capacity is 6 GB. Hard drives can be individually selected, with sources recommending the use of Synology hard drives. RAID modes (0, 1, JBOD) allow adaptation to requirements for performance, redundancy, or total capacity. The platform is designed for use in small networks, with central management of multiple devices supported via DSM.

Central Management and Monitoring

The platform enables central monitoring and management of Synology devices, with configuration performed via a central interface. Management is performed via the DSM operating system, accessible through a web browser. Functions include management of users, shares, backups, applications, and video surveillance cameras. The central interface enables control of multiple devices, with management possible on-site or in the cloud.

Security and Backup

The platform offers backup functions enabling data backup to cloud services. Integrated support for RAID modes (0, 1, JBOD) provides options for data protection and redundancy. The video surveillance function enables storage of surveillance data on internal drives. Management of users and shares enables control over data access. Security functions are integrated into the DSM operating system and can be configured via the web interface.

Hardware-Software Integration

The platform uses hardware-software integration, with Synology hard drives specifically optimized for use with DSM. This ensures reliability, consistent performance, and simplified system management. The use of other hard drives is not explicitly confirmed, so compatibility is not guaranteed. The integration ensures optimal coordination between hardware and operating system.
