5-Bay Expandable Desktop NAS
Synology DS1525neo+ Network Attached Storage
A versatile five-bay data hub designed to adapt as storage needs grow, with an AMD Ryzen V1500B processor, 4 GB DDR4 non-ECC memory, dual 2.5GbE networking, two M.2 NVMe cache slots, optional 10GbE networking and expansion to 15 drive bays with two DX525 units.
A flexible data hub for storage, protection and collaboration
The Synology DS1525neo+ is a five-bay desktop NAS built for growing storage environments. It combines dual 2.5GbE connectivity, two M.2 NVMe slots for cache, a dedicated network-upgrade slot for optional 10GbE and support for two DX525 expansion units. Synology applications extend the system into a private cloud, backup platform, multi-site synchronisation hub, surveillance system and application-testing environment.
Key features and benefits
Five-bay storage with expansion
Use up to 120 TB of raw storage across five bays, then expand to 15 bays and up to 360 TB of raw capacity with two DX525 expansion units when using 24 TB drives.
Dual built-in 2.5GbE
Two 2.5GbE RJ-45 ports provide fast out-of-the-box connectivity for shared storage, backup and everyday multi-user access.
Optional 10GbE networking
A Gen3 x2 network upgrade slot supports the listed E10G22-T1-Mini module for faster network connectivity when required.
Two M.2 NVMe cache slots

Important information
Performance figure conflict: the supplied product copy contains two different sequential performance claims: 1,181/1,180 MB/s and 696/862 MB/s read/write. The exact figure has therefore not been promoted in the hero or key-specification sections.
SSDs are sold separately. Check compatible drive, SSD, memory and network-upgrade-module requirements before purchase.
Synology only guarantees full functionality, reliability and performance for compatible drives.
The stated performance figures are based on Synology internal testing. Actual performance may be lower due to differences in server configuration, deployment and the number of active operations.
Noise testing was conducted with the Synology system fully installed with Synology SATA HDDs and in an idle state.
Model specifications are subject to change without prior notice.
