Scalable NAS with SSD cache acceleration capability
Suitable for small office and IT enthusiasts, this five-bay network attached storage solution offers a centralized, remotely accessible location to back up, protect and share your data. You can also collaborate with co-workers on the same online document, run and manage multiple virtual machines, and stream media to various devices — computers, smartphones, media players, and TVs — for non-stop, fun watching experience.
Hardware-wise, the DS1520+ is powered by an Intel quad-core processor, and comes with four Gigabit Ethernet ports that support Link Aggregation and Failover. Two built-in M.2 SSD slots and Synology SSD Cache technology allow you to boost system I/O and application performance. It also supports scalable storage design, so you start small and expand storage capacity with optional Synology DX517 as your data grows.
