Sync files and folders between sites
Benefit from two efficient ways to keep files and folders synchronized between different locations — such as your home and your business, or teams in different countries. Sync folders one or two-way between Synology devices using
Synology Drive ShareSync, a free site-to-site solution. Or choose to leverage our secure data centers to store your data in the cloud, while keeping a cache of frequently accessed or manually pinned files on your DS1522+ with
Synology Hybrid Share. Such hybrid cloud storage lets you access data at LAN speeds without being limited by your local storage size or bandwidth.
Boost storage performance
Accelerate HDD arrays with an M.2 NVMe SSD adapter card and SNV3000 series SSDs, or install SAT5200 SATA SSDs in drive bays to increase performance with SSD cache.
Do both with one card
Add both 10GbE connectivity and M.2 NVMe SSD slots for SSD cache with a single combination NIC and adapter card.
