Synology DiskStation DS1525+ 5-Bay Plus Series NAS

The Synology DiskStation DS1525+ is a scalable 5-bay desktop NAS powered by an AMD Ryzen processor with 8GB ECC memory, dual 2.5GbE networking, two M.2 NVMe slots and expansion support for up to 15 drives.

Product Description

The Synology DiskStation DS1525+ is a versatile 5-bay network attached storage system designed for centralised file storage, business backup, collaboration, virtualisation and surveillance.

It is powered by an AMD Ryzen V1500B processor with four cores, eight threads and a 2.2GHz operating frequency.

The system includes 8GB of DDR4 ECC SODIMM memory and supports expansion to a maximum of 32GB using compatible Synology memory modules.

Five hot-swappable drive bays support compatible 3.5-inch SATA hard drives and 2.5-inch SATA solid-state drives.

Two built-in M.2 2280 NVMe slots can be used for compatible SSD caching or supported M.2 storage pools without occupying the front drive bays.

Storage capacity can be expanded to a maximum of 15 drives by connecting up to two optional Synology DX525 Expansion Units.

Dual built-in 2.5GbE network ports provide faster connectivity than standard Gigabit Ethernet and support Link Aggregation, failover and load balancing with compatible network equipment.

An optional Synology E10G22-T1-Mini Network Upgrade Module can add one 10GbE RJ-45 network port.

Synology lists sequential performance of up to 1,181MB/s read and 1,180MB/s write in supported test configurations using upgraded networking.

Synology DiskStation Manager provides tools for file sharing, backup, private-cloud storage, photo management, collaboration, virtualisation and surveillance.

Synology Drive supports file access, synchronisation, sharing and computer backup, while Synology Photos provides private photo and video organisation.

Active Backup Suite supports compatible computers, servers, virtual machines and selected cloud applications. Hyper Backup can protect data to compatible local, remote and cloud destinations.

Surveillance Station includes two default device licences and supports up to 40 compatible IP cameras, depending on the recording configuration and other active workloads.

The DS1525+ is supplied without storage drives, M.2 SSDs, expansion units or the optional 10GbE module.

Specifications

Compatibility Note

Please confirm that all storage drives, M.2 SSDs, memory modules and optional accessories are officially compatible with the Synology DS1525+ before ordering.

The DS1525+ supports:

• Up to five compatible 3.5-inch SATA hard drives
• Up to five compatible 2.5-inch SATA solid-state drives
• Up to two compatible M.2 2280 NVMe SSDs
• Up to two Synology DX525 Expansion Units
• Synology D4ES03-8G and D4ES03-16G memory modules
• Synology E10G22-T1-Mini 10GbE Network Upgrade Module

M.2 SSD support is model-dependent. Compatible M.2 SSDs may be used for caching or supported storage pools, but only Synology-verified SSDs should be used where required.

The front SATA drive bays support hot-swapping when permitted by the current RAID and storage-pool condition. The M.2 SSD slots do not support hot-swapping.

All memory modules in a multi-module configuration must be identical and use the same model number.

A maximum single volume size above 108TB requires at least 32GB of installed memory and a supported storage configuration.

The available storage capacity will be lower than the total manufacturer-rated drive capacity because of RAID, formatting, system partitions and file-system data.

Actual performance depends on the installed drives, RAID configuration, network equipment, client hardware, memory configuration and active applications.

RAID helps protect against selected drive failures but does not replace an independent backup.
