With the new DS425+, Synology expands its portfolio of powerful NAS systems with a compact 4-bay model that is suitable for both demanding home users and small businesses. Equipped with the latest hardware and comprehensive software features, the DS425+ provides a solid foundation for data backup, media management, private cloud applications and more. The combination of compact design and strong performance makes the system an interesting option for anyone looking for a reliable and versatile NAS.
- 4 bays for up to 72 TB total capacity (with 18 TB HDDs)
- Quad-core processor with hardware encryption
- Dual 1GbE LAN with link aggregation
- Supports Synology DSM 7.2 and numerous apps for backup, media streaming and virtualization
Powerful NAS in a compact housing
The DS425+ is based on an Intel Celeron J4125 quad-core processor with 2.0 GHz (burst up to 2.7 GHz), which is particularly suitable for simultaneous services such as file sharing, media streaming and backup. The CPU is supported by 2 GB DDR4 RAM, which can be expanded to up to 6 GB. This allows the device to handle multiple parallel tasks without any noticeable loss of performance – such as simultaneous use as a media server, cloud storage and backup destination.
The NAS offers four drive bays that can be equipped with 3.5″ or 2.5″ HDDs/SSDs. With the currently available 18 TB hard disks, this results in a potential total storage capacity of up to 72 TB, which is perfectly sufficient for use in small workgroups, content creation projects or as a central family backup. Hot-swappable bays facilitate the replacement of drives during operation.
Two 1 Gigabit Ethernet ports are available for connection to the network, which can be bundled via link aggregation to a combined bandwidth of 2 Gbps. This means that even large amounts of data can be transferred quickly – a plus point for regular access by multiple users or for synchronization with cloud services.
Software and functions for a wide range of application scenarios
he central highlight of the DS425+ is the DiskStation Manager (DSM) 7.2 operating system, which offers a wide range of functions – from a simple file explorer and comprehensive backup solutions to virtualization and Docker support. For example, you can set up a private cloud with Synology Drive, manage complete PC or server backups with Active Backup or integrate a video surveillance system with Surveillance Station.
Multimedia functions are not neglected either: Audio Station, Video Station and Photos enable clear management, conversion and sharing of media files – whether locally, via DLNA or over the Internet. Support for Plex servers offers additional flexibility for streaming.
Especially for users with high security requirements, Synology offers integrated functions such as two-factor authentication, file-level encryption and snapshot technology for restoring previous data statuses. Thanks to the Virtual Machine Manager app, virtual machines can even be operated directly on the NAS – for example for test environments or isolated applications.
Conclusion
The Synology DS425+ combines powerful hardware with a sophisticated software ecosystem in a compact 4-bay NAS. It offers reliable performance for everyday use, whether in the home office, in creative studios or in the family network. With a recommended retail price of around €470 (housing without hard disks), it is not the cheapest solution on the market, but justifies the price with high flexibility, data security and user-friendliness. The model is available immediately from specialist retailers and selected online stores. Further details can be found on the official website.
