SuperSpeed USB 3.0 accelerates transfer rates

DS215j comes with USB 3.0 ports to connect to various kinds of external storage devices, while ensuring fast and efficient file transfer speeds. Support for USB 3.0 offers transfer speeds of up to 5 Gbps (about 10 times faster than USB 2.0), meaning it takes less time to transfer data to external hard drives, while also consuming less power.

Award winning OS - DiskStation Manager

Synology DiskStation Manager (DSM) is a sleek, browser-based operating system running on every DiskStation and RackStation, which makes managing your Synology NAS a breeze. Featuring an intuitive user interface, DSM makes accessing and sharing your data smarter and simpler.

Your files anywhere with cloud service

DS215j brings you comprehensive cloud service. Cloud Station lets you sync files among DiskStations and multiple devices, including Windows PC, Mac, Linux, iOS, Android, as well as Windows mobile devices, whereas 2-way sync allows file synchronization among different DiskStations. You can even sync files between Google Drive, Dropbox, Baidu and DiskStation - establish your hybrid cloud to enjoy more storage flexibility and prevent data loss.

Backup data in multiple ways

No worries about data loss. DS215j is the perfect backup destination for your data, as it supports Windows Backup for Windows users, whereas Mac users enjoy native Time Machine support. You can choose your backup destination to not only be local hard disks, but also connected USB storage devices. Additionally, Backup & Replication allows you to schedule backup tasks and restore the server to any particular point in time, while still minimizing storage consumption and processing time by saving only the specific data block that has been changed between versions.

The most compatible sharing

Enjoy seamless files sharing across Windows®, Mac®, and Linux® platforms as DS215j offers comprehensive network protocol support including FTP, SMB2, AFP, NFS and WebDAV. With Windows AD and LDAP integration, DS215j can fit effortlessly into any existing network environment - there is no need for IT administrators to maintain two sets of credentials. You also won't worry about missing files with the Recycle Bin feature which is supported on AFP, CIFS, File Station, and WebDAV. All files deleted in a shared folder will be automatically moved into the Recycle Bin.
