The DS1525+ is a versatile 5-bay NAS designed to scale with your needs. Start fast with the integrated 2.5 GbE port and add performance with optional SSD caching. When it's time to grow, attach the DX525 expansion unit (sold separately) to build out to as much as 300 TB of raw capacity. Powered by DiskStation Manager (DSM), DS1525+ delivers an all-in-one solution for file sharing and synchronization, backup and data protection, media organization, virtualization, and private video surveillance. Its strong sequential throughput—up to 1,181 MB/s read and 1,180 MB/s write—keeps transfers responsive, while the streamlined DSM interface makes setup and daily management simple for users of all levels. For IT teams and creators, DS1525+ integrates smoothly into virtualized environments and can be used as VM storage, a lightweight container host, or a small edge server across VMware vSphere, Microsoft Hyper-V, Citrix XenServer, and OpenStack.
