Overview

Synology DS1825neo+ 8-Bay NAS Storage Solution
The Synology DS1825neo+ is a high-capacity 8-bay NAS designed for businesses, professional users and demanding home environments that need secure, scalable and flexible network storage. Powered by an AMD Ryzen V1500B 4-core processor with 4GB of DDR4 ECC [sic] memory and two memory slots, it provides a solid platform for file storage, backup, collaboration, surveillance and data management. With support for up to 8 internal SATA drives and expansion to 18 drive bays, the DS1825neo+ can grow as storage requirements increase.

Description

The Synology DS1825neo+ combines fast networking, flexible storage options and a broad range of data management applications in a desktop NAS chassis. Two built-in 2.5GbE LAN ports provide high-speed network connectivity, while two M.2 2280 NVMe slots can be used for SSD caching. Users can install 3.5-inch SATA hard drives or 2.5-inch SATA SSDs in the eight hot-swappable drive bays, with expansion units allowing the system to reach up to 18 drive bays.

The NAS is designed to handle demanding business workloads, including centralized file management, automated backups, multi-site synchronization, private cloud services and IP video surveillance. With a compatible expansion card, networking can be upgraded to support speeds of up to 25GbE, making the DS1825neo+ suitable for environments where large files and high transfer rates are important.

Features

High-Capacity 8-Bay NAS With Expansion Support
The DS1825neo+ provides eight internal drive bays for consolidating documents, media, business files, backups and other data in one centralized storage system. Storage capacity can be expanded by connecting compatible Synology expansion units, providing up to 18 drive bays in total.

Using 24TB drives, the platform can provide up to 192TB of raw capacity across the eight internal bays and up to 432TB of raw capacity when expanded to 18 bays.

• 8 internal drive bays
• Up to 18 drive bays with expansion
• Up to 192TB raw capacity across the internal bays
• Up to 432TB raw capacity with expansion using 24TB drives
• Hot-swappable drive design
• Supports 3.5-inch SATA HDDs and 2.5-inch SATA SSDs

Fast 2.5GbE Networking and NVMe Cache
Two built-in RJ-45 2.5GbE ports provide faster network transfers than standard Gigabit Ethernet and can help improve performance when moving large files across a suitable network. The DS1825neo+ also includes two M.2 2280 NVMe SSD slots for cache applications, allowing frequently accessed data to benefit from faster storage response.

With suitable hardware and network infrastructure, the system can achieve sequential read and write performance of up to 2,239 MB/s and 1,573 MB/s respectively. An optional networking expansion card can further increase connectivity to up to 25GbE.

• 2 x RJ-45 2.5GbE LAN ports
• 2 x M.2 2280 NVMe SSD slots for cache
• Up to 2,239 MB/s sequential read performance
• Up to 1,573 MB/s sequential write performance
• Optional networking expansion supporting up to 25GbE

Flexible Storage for Business and Professional Users
The DS1825neo+ supports a combination of SATA hard drives and SSDs, allowing the storage configuration to be matched to the workload. High-capacity HDDs can be used for economical bulk storage, while SATA SSDs and NVMe cache can help improve responsiveness for frequently accessed data.

The hot-swappable drive bays also make storage maintenance and upgrades more convenient, particularly in environments where minimizing downtime is important.

Private Cloud File Storage and Collaboration
Synology's software ecosystem turns the DS1825neo+ into more than a basic network file server. Users can store, synchronize, access and share files across computers, mobile devices and web browsers while maintaining control over business data.

Versioning helps users recover previous versions of files following accidental deletion, unwanted changes or other incidents. The system can also support collaborative document workflows, private communication tools and other productivity applications.

For businesses with multiple offices or remote workers, NAS-to-NAS synchronization can keep selected files and folders updated between locations. Data can also be synchronized with supported public cloud services such as Backblaze B2, Dropbox, Google Drive and Microsoft OneDrive.

Centralized Backup and Data Protection
The DS1825neo+ can act as a central backup destination for PCs, servers, virtual machines, SaaS applications and other devices. Automated backup tasks can be managed from a centralized interface, while recovery tools help restore individual files or complete systems when required.

Synology backup solutions can also be used to protect the NAS itself by backing up data, applications and configurations to local or remote systems, external storage or supported cloud destinations.

Immutable snapshots provide another layer of protection for critical shared folders and LUNs. Retention policies and offsite replication can help strengthen recovery planning and business continuity.

IP Camera Surveillance Storage
The DS1825neo+ can also be used as a centralized video surveillance platform through Synology Surveillance Station. It supports a large range of compatible IP cameras and provides tools for live monitoring, recording, playback and investigation.

The system can be useful for businesses that want to combine file storage and surveillance management on one NAS platform. Compatible cloud backup options can also provide additional protection for important surveillance recordings.

Virtual Machines and Container Applications
Beyond file storage and backup, the DS1825neo+ can provide a flexible environment for testing and running applications. Support for Docker containers and virtual machines makes it possible to create isolated environments for development, testing and other workloads.

Virtual DSM can also be used where an isolated testing environment is required, helping separate applications and workloads from the primary NAS environment.

Centralized NAS Management
For businesses operating several Synology systems, centralized management tools can simplify administration. Synology Central Management System provides a central console for managing servers, applying group policies, delegating tasks and carrying out batch updates.

Active Insight provides cloud-based monitoring of Synology systems, including performance information, backup status and login activity, helping administrators keep track of NAS environments across different locations.

Connectivity and Expansion
The DS1825neo+ provides a useful selection of connectivity options for storage, networking and expansion.

• 2 x 2.5GbE RJ-45 LAN ports
• 3 x USB 3.2 Gen 1 ports
• 2 x USB Type-C expansion ports
• 2 x M.2 2280 NVMe slots
• 8 x internal SATA drive bays
• Expansion support for up to 18 total drive bays
• Optional networking expansion up to 25GbE

AMD Ryzen Processing and Memory
An AMD Ryzen V1500B 4-core processor provides the processing platform for file services, backup applications, synchronization, surveillance and other NAS workloads. The system includes 4GB of DDR4 SO-DIMM memory and provides two memory slots for supported memory configurations.

The combination of Ryzen processing, 2.5GbE networking and NVMe caching makes the DS1825neo+ well suited to users who need more than basic network storage.

Synology Drive Compatibility
The DS1825neo+ can be paired with compatible Synology HDD and SSD storage solutions designed for use in Synology systems. Using compatible drives can provide consistent performance and simplify drive and system management.

For environments where the NAS is expected to operate continuously, choosing drives appropriate for NAS workloads is important.

A Scalable NAS for Growing Storage Requirements
The Synology DS1825neo+ is designed to provide a long-term storage platform that can expand as requirements change. Starting with eight drive bays and supporting expansion to 18 bays, it can accommodate growing collections of business files, backups, surveillance recordings and other data.

The combination of dual 2.5GbE networking, NVMe caching, optional 25GbE connectivity, hot-swappable storage and Synology's backup, collaboration and surveillance applications makes it a versatile choice for businesses and professional users.

The part number / SKU for this model is DS1825neo+, making it easier to identify the correct Synology NAS when ordering or checking compatibility.
