Overview

DS925neo+: Versatile 4-bay storage with expansion options

The Synology DS925neo+ is a 4-bay 2.5"/3.5" NAS designed for advanced users looking for an advanced, expandable storage solution, with the option to add 5 additional bays using the DX525 expansion unit. Overall responsiveness can be improved by installing 2 NVMe SSDs for read and write caching. For external connectivity, the Synology DS925neo+ offers 2 2.5 GbE LAN ports to ensure smooth transfers to and from the NAS. Powered by Synology DiskStation Manager (DSM), the DS925neo+ offers a flexible all-in-one solution for data sharing, synchronization, backup, and surveillance.
 

Versatile storage for every use

  • Sequential read speeds of up to 522 MB/s and sequential write speeds of up to 565 MB/s enable fast file sharing, synchronization, streaming, and backup for multiple users.
  • Supports 4 2.5"/3.5" SATA HDDs/SSDs, expandable to 9 drives with a Synology DX525 expansion unit.
  • Up to 32 GB of non-ECC DDR4 memory to protect against potential crashes and accidental data changes through automatic data error correction.
  • Two RJ45 2.5 GbE ports can be linked using link aggregation to provide automatic network failover and load balancing.
  • Upgrade your storage platform to meet the most demanding needs with two built-in M.2 2280 NVMe SSD slots.

Private cloud

Access files from all your devices and protect them with intelligent version management. Manage, share, and synchronize your data across multiple sites.

  • Create your own personal cloud with Synology's private cloud solution. Simplify file access and consolidate data management to make file sharing and collaboration easier.
  • Back up and organize your photos and videos efficiently with management tools for hobbyists and professionals. Automatically organize your content into albums and create secure sharing links for your family, friends, or clients.
  • File synchronization between sites lets collaborators synchronize individual files or folders between Synology devices, whether at home, in the office, or around the world. Combine convenient access with complete data ownership.
  • Reduce the footprint of your on-site storage and benefit from the network throughput offered by data centers with hybrid cloud technology. Configure Hybrid Share folders to store your cold data efficiently in the cloud, while keeping frequently used files cached locally on your DS925neo+ and accessible at LAN speeds.

Multi-layer backup

Back up files, folders, physical devices, virtual machines, and SaaS applications using free solutions, and protect your NAS with built-in technologies.
  • Consolidate and automate backup tasks for PCs, file servers, virtual machines, SaaS applications, and more with Active Backup Suite. Manage device backups remotely through a centralized portal and quickly restore specific files or entire devices to keep your business running smoothly. Built-in remote backup solutions make it easy to set up 3-2-1 backups.
  • Protect all data, applications, and configurations on your Synology systems with scheduled full backups to local and remote servers, external drives, or cloud storage destinations, including Synology C2 Storage.
  • Set up efficient snapshots of shared folders and LUNs at a specific point in time, at intervals as short as five minutes. Let users easily restore previous file versions without assistance, quickly recover virtual machines, and copy snapshots to another server for rapid storage failover.

Intelligent surveillance

Turn your Synology device into a complete video management system for a wide range of compatible IP cameras.

  • Protecting your business has never been easier, thanks to centralized management, support for more than 8,300 IP camera models, and remote monitoring and playback. Synology's video management system provides all the tools you need for live surveillance, investigation, management, and backup.
  • C2 Surveillance lets you continue accessing surveillance footage if your recording server is disabled by recording it on both your local server and C2 Cloud. End-to-end encryption protects streams from unauthorized access, while low-latency recording lets you view the crucial last few seconds recorded before losing connection to the server.
