Capacity-scalable NAS with SSD Cache Acceleration Capability

Synology DiskStation DS1520+ is an ideal network-attached storage solution, suitable for small office and IT enthusiasts. Two builtin M.2 SSD slots and Synology SSD Cache technology allow you to boost system I/O and application performance. With scalable storage design, DS1520+ lets you start small and expand storage capacity with the Synology DX517 as your data grows.

Streamline Your Data Management Experience

Synology DS1520+ is a powerful 5-bay desktop NAS that brings you a fast and smooth data management experience. Featuring four 1GbE LAN ports with network failover support, DS1520+ provides 451.28 MB/s sequential read and 451.18 MB/s sequential write throughput with Link Aggregation enabled3.
