Download Datasheet

CPU

2 x 10-core Intel Xeon Silver

Throughput

Over 6,688/6,662MB/s sequential read/write

Memory

64 GB DDR4 ECC, expandable to 512 GB

Private cloudA private cloud suite for file sharingSynology Drive is a private cloud management and access solution that enables remote data access, synchronization, on-demand file restoration, and backup via desktop and mobile applications. Sync data between different platforms and devices, and access your organization’s files through mobile apps, desktop clients, and a browser-based interface. Set granular file and folder access and sharing permissions. Maintain a full overview of file activities and track file share settings changes with detailed records in the advanced Synology Drive Admin Console. Learn moreCross-site syncingLeverage SMB or NFS shares to provide efficient access to company files over the local network or VPN. Manage data access privileges with access control lists (ACL) though Active Directory/LDAP integration and protect files against tampering or removal with built-in snapshot technology.
Cross-site syncingSecure site-to site file and folder syncingMake sure branches or teams always have up-to-date copies of crucial documents and data available locally by syncing folders one or two-way using Synology Drive ShareSync. Let your Synology systems update files across locations each time there is a change to efficiently keep all stakeholders on the same page. Learn moreEfficient cross-site syncing through the cloudSecurely synchronize files and data from the HD6500 to Synology systems across different sites or offices, and back, by leveraging hybrid cloud technology with Synology Hybrid Share. Synchronize large sets of data to the cloud, and leverage the powerful bandwidth of our data centers to stream requested files to local NAS deployed at branch offices, no matter their size. Frequently used files are kept stored on local NAS to provide users access at LAN speeds and can also be pinned manually to prevent them from being removed from the cache. Learn more
