SYNOLOGY – DISKSTATION 4-BAY NAS – AMD RYZEN V1500B – 4GB NON-ECC RAM – 2.5GbE – DS925NEO+

High-Performance Processing and Memory

The Synology DiskStation DS925neo+ 4-Bay NAS offers a premium storage platform centered around the AMD Ryzen Embedded V1500B quad-core processor. Operating at 2.2 GHz with an 8-thread architecture, this 64-bit powerhouse is fully optimized to tackle demanding multitasking environments, high-volume file sharing, and rigorous business workloads effortlessly. To guarantee swift application responses and seamless data accessibility, the DS925neo+ is pre-installed with a 4 GB DDR4 Non-ECC SODIMM memory module. As your data needs escalate, the system is designed to grow with you. Utilizing the dual SODIMM memory slots, administrators can expand the system memory up to a remarkable 32 GB (via two 16 GB modules), paving the way for intensive virtual machine deployments and extensive database operations. For those needing advanced error-checking, the motherboard fully supports Synology’s DDR4 ECC SODIMM memory upgrades as well.

Exceptional Storage Expandability and SSD Caching

Out of the box, the DiskStation DS925neo+ provides four lockable, hot-swappable drive bays ready to accept high-capacity 3.5-inch SATA HDDs or lightning-fast 2.5-inch SATA SSDs. Whether you are building an expansive media vault or a high-speed editing server, the flexibility of Synology Hybrid RAID, RAID 5, or RAID 10 allows you to finely tune your balance between performance and redundancy. For environments that quickly outgrow the internal storage pool, the DS925neo+ includes a dedicated USB Type-C expansion port, supporting seamless integration with the Synology DX525 5-bay expansion unit. This allows scaling up to a massive 9 total drive bays, supporting an internal volume size of up to 108 TB natively, or 200 TB if memory is expanded to 32 GB.

To further accelerate performance without sacrificing crucial primary storage bays, this NAS integrates two dedicated M.2 2280 NVMe SSD slots. By populating these slots with compatible NVMe drives (such as the Synology Enterprise Series SNV3410 or SNV5420), you can effortlessly create ultra-fast read/write cache pools or distinct high-speed storage volumes. This substantially reduces input/output latency, allowing random operations to execute near instantaneously.

Next-Generation 2.5GbE Networking and Accessibility

Network bottlenecks are effectively eliminated with the inclusion of dual 2.5 Gigabit Ethernet (2.5GbE) RJ-45 ports. These ports dramatically enhance the bandwidth available compared to traditional Gigabit hardware, enabling sequential read speeds of up to 536 MB/s and write speeds of up to 557 MB/s. Furthermore, these dual ports support Link Aggregation, allowing you to bond the connections for failover protection and advanced load balancing. Should one network line fail, the system instantly switches to the secondary connection, ensuring that your enterprise data or collaborative projects remain online and accessible. Additional external device connectivity is provided via two high-speed USB 3.2 Gen 1 (USB-A) ports, perfect for external backup drives or peripheral devices.

Advanced File Management, Virtualization, and Protection

Running on the universally praised Synology DiskStation Manager (DSM) operating system, the DS925neo+ delivers a comprehensive suite of tools for professional data management. The system supports a wide range of networking protocols—including SMB, AFP, NFS, FTP, and WebDAV—ensuring cross-platform harmony whether you operate in a Windows, macOS, or Linux environment. For enterprise virtualization, it is officially certified for VMware vSphere, Microsoft Hyper-V (including Windows Server 2025), Citrix XenServer, and OpenStack, and supports up to 64 iSCSI LUNs.

Security is deeply integrated at every level. Your data is protected by the powerful Btrfs file system, which offers advanced snapshot technology and self-healing data capabilities to prevent bit rot. Paired with a dedicated hardware encryption engine, your sensitive files can be heavily protected with minimal performance impact. Additionally, centralized data backups are managed through Synology’s ecosystem, allowing you to back up PCs, VMs, and SaaS applications securely to the NAS, while syncing to major cloud providers if offsite redundancy is required.

Efficient Design and Silent Operation

Despite its powerful internal specifications, the DS925neo+ is remarkably compact, measuring just 166 × 199 × 223 mm and weighing a lightweight 2.26 kg. This sleek, black desktop chassis blends effortlessly into any office or home studio environment. Thermal management is handled by two intelligent 92 mm system fans located on the rear panel. These fans feature customizable profiles (Full-Speed, Cool, and Quiet Modes) to ensure the system runs at optimal temperatures ranging between 0–40°C. In Quiet Mode, the NAS produces a whisper-quiet 20.5 dB(A) noise level, ensuring it never disrupts your creative or professional workflow. Power efficiency is equally impressive; the device draws only 37.91 W during active data access, dropping to a mere 12.33 W when the hard drives enter hibernation mode.
