Key Features
Five-Bay Storage with Dual Expansion Support
Five hot-swappable SATA bays offer a practical starting point for capacity and RAID flexibility. Two optional DX525 units expand the system to 15 total drives and up to 360 TB of raw storage using 24 TB drives.
Built-In 2.5GbE with a 10GbE Upgrade Path
Dual 2.5GbE ports support link aggregation and failover out of the box. A supported E10G22-T1-Mini module can add 10GbE connectivity, with Synology test performance reaching up to 1,181 MB/s read and 1,180 MB/s write in a supported configuration.
M.2 NVMe Acceleration and Storage
Two M.2 2280 NVMe slots support compatible SSDs for cache and supported SSD storage pool configurations. SSDs and the optional network module are sold separately.
Private Cloud and Team Collaboration
Synology Drive, Synology Office and Hybrid Share provide controlled file access, synchronisation and collaboration across computers, mobile devices and multiple sites.
Centralised Backup and Recovery
Active Backup Suite, Hyper Backup and Snapshot Replication protect endpoints, servers, virtual machines, Microsoft 365, Google Workspace and NAS data. Selected services and advanced capabilities may require separate licences or subscriptions.
Surveillance and Virtualisation
Surveillance Station supports up to 40 IP cameras and includes two device licences. Virtual Machine Manager supports up to eight virtual machines and includes one Virtual DSM licence; extra licences are sold separately.
Neo+ Memory Choice
DS1525neo+ includes 4 GB DDR4 non-ECC SODIMM memory and can be expanded to 32 GB. The standard DS1525+ ships with 8 GB ECC memory, so buyers needing ECC protection or more memory out of the box should choose that model.
Compatibility and Support
Check Synology's current compatibility list for hard drives, SSDs, memory, network modules and expansion units. Drives, SSDs, optional modules and expansion units are not included.
Summary
DS1525neo+ suits businesses and creators that need more capacity than a 4-bay system, with room to scale through dual expansion units and optional 10GbE. Its 5-bay design, NVMe flexibility and broad DSM software suite make it a capable central data hub at a lower entry cost than the ECC-equipped DS1525+.
Synology DS1525neo+ DiskStation 5-Bay 2.5GbE Tower NAS
The Synology DS1525neo+ is an adaptable 5-bay desktop NAS for centralised storage, backup, collaboration and surveillance. It combines a 4-core AMD Ryzen V1500B processor, 4 GB DDR4 non-ECC memory, dual 2.5GbE networking, two M.2 NVMe slots and an optional 10GbE upgrade. Two DX525 expansion units can increase capacity to 15 drives and 360 TB raw. The neo+ configuration offers a lower entry cost than the 8 GB ECC-equipped DS1525+ while retaining the same core platform.
