DiskStation DS3018xs

Powerful 6-bay NAS designed for work-intensive businesses

 

High-performance NAS server with scaling flexibility

Powered by a dual-core processor with AES-NI hardware encryption engine, Synology DiskStation DS3018xs is a brand new 6-bay NAS that comes with a PCIe slot and can be installed with a 10GbE network interface card or a dual M.2 SSD adapter card. SSD cache support enhances network speeds and boosts performance, allowing DS3018xs to meet data-intensive requirements.

 

 

Supercharge your storage with speedy performance

Equipped with dual-channel memory and a PCIe slot, DS3018xs supports installing the dual M.2 SSD adapter card, M2D17, or the 10GbE NIC, for high-IOPS system cache and ultra-fast data transmission respectively.

 

 

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 all 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 makes data recovery fast and flexible

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

 

Fully certified storage virtualization solutions

Synology iSCSI storage fully supports most virtualization solutions to enhance work efficiency with easy management interface. VMware vSphere 6 and VAAI integration helps offload storage operations and optimizes computation efficiency. Windows Offloaded Data Transfer (ODX) speeds up data transfer and migration rate. OpenStack Cinder support turns your Synology NAS into a block-based storage component.
