10GbE

10GbE network capacity for bandwidth intensive environments

5 Year Warranty

Synology’s 5-year limited warranty provides hardware replacement and technical support via email and telephone services, maximizing your enterprises’ return on investment.

Synology Replacement Services(SRS)

SRS provides free advance replacement units as early as the next business day in selected regions, maximizing the service uptime for your mission-critical storage and ensuring your business continuity.

RAID F1

Due to the peculiarities of SSD and RAID technology, a common challenge lies in how to prevent all of the drives from failing at the same time because of the evenly distributed workload. RAID F1 alleviates this problem with a specially designed algorithm to unevenly distribute workload to drives, enhancing the resilience of the storage pool and ensuring your data remains safe.

Next-generation file system for better data protection

The Btrfs file system introduces advanced storage technologies and optimized snapshots to prevent data corruption and reduce maintenance overhead. While ensuring high-level data integrity, it also offers flexible, efficient data protection and recovery tools.

Flexible Shared Folder / User Quota System provides comprehensive quota control on user accounts and shared folders

Snapshot Replication provides schedulable and storage capacity-saving data protection with 1,024 shared folder backups and 65,000 system-wide snapshots

 
File- or folder-level data restoration accelerates data recovery, providing more flexibility for businesses

 
Automatic file self-healing detects and recovers corrupted files without user intervention

Virtual Machine Manager

Virtual Machine Manager enables you to test new software in sandboxes, isolate your customers’ machines, and increase the flexibilit of your server. You can easily run Windows, linux, and Virtual DSM on your synology NAS by just a few steps.

Snapshots for virtual machines

Perfectly clone and restore a virtual machine within seconds.

Live migration

Seamlessly migrate Virtual DSM instances from a Synology NAS to another.
