Intuitive management Accelerate storage management tasks through a centralized interface.

Round-the-clock reliability Ensure service continuity with systems designed for dependability.

Store efficiently Reduce cost of ownership with efficient data compression and deduplication.

On-demand scalability Scale up your storage capacity without affecting operations.

Manage efficiently

Clear insights

See at a glance how your storage is organized and how much of it is available through an informative interface.

Simple management

Conduct array repairs and drive replacement, set up hot spares, and more through easy-to-understand wizards and processes.

Multi-level redundancy

Protect your services against downtime with high-availability and data backup solutions built directly into Synology DiskStation Manager (DSM).

Reliability

Actively protect your digital assets against data corruption.

Data scrubbing and file self-healing Rely on data integrity systems to find and prevent file corruption through metadata mirroring.

Fast and efficient snapshots Enable quick and easy point-in-time recovery of shared folders and LUNs.

Maintenance made easy

Auto Replacement

Prevent storage pool degradation by letting Synology DSM automatically clone failing drives to available hot spares.

Fast Repair

Minimize the time needed to bring RAID arrays back to a healthy state by only repairing sectors that are currently in use.

Maximize storage efficiency

Get the most out of your storage with powerful optimization features.

Data compression Reduce average storage consumption in shared folders by up to 30%.

Instant SMB/AFP server-side copy Reference existing data blocks instead of copying them if the source and destination are both on the same Btrfs volume.

Flash volume deduplication Maximize storage efficiency by eliminating identical data blocks with volume-wide deduplication on all-flash arrays.¹

Accelerate data access

Rapid write-back

Faster data write-back speeds up synchronization from SSD cache to HDD and automatically protects cached data.

Btrfs metadata caching

Store all Btrfs metadata to your SSD cache to speed up response and accessing times for all files.

Store securely, stay compliant

Immutable storage

WriteOnce technology prevents modification or deletion of sensitive data. This makes it ideal for archiving and maintaining regulatory compliance.

Protected snapshots

Immutable snapshots can be stored locally or replicated to an off-site Synology NAS, assuring they remain safe from modification and secure against physical disaster.

Securing data against theft and loss

Volume encryption and shared folder encryption are both effective methods of maintaining data security with several important differences between them. Learn more

Volume Encryption vs. Shared Folder Encryption

	Volume Encryption	Shared Folder Encryption
Encryption targets	Volumes (Shared Folders, package data, and LUNs)	Shared Folders
Max. file name length	255 chars.	143 chars.
Automount Key Storage	Local: Host storage	Local: Host storage
Automount Key Storage	Remote: Separate Synology NAS (KMIP)	—

Keeping sensitive data out of reach Encrypt data on specific shared folders or apply volume-wide encryption to all files and LUNs to prevent data leaks resulting from the physical theft of hardware.

Secure key management Encryption Key Vault supports local and KMIP key storage, enabling auto-decryption of encrypted folders or volumes on startup. Admins can adopt different options to balance convenience and threat mitigation.

Expand whenever

On-demand expansion

Add new drives with just a few clicks and without interrupting your services as your storage requirements grow.

Flexible deployment

Combine drives of different capacities to create arrays that take full advantage of each drive's available storage with Synology Hybrid RAID (SHR).²

High-capacity storage

Optimize your storage for data archives or video management systems (VMS) by creating single volumes that reach up to a Petabyte.³

Notes: Flash volume deduplication is available on flash-only volumes comprised of compatible Synology SSDs. Synology measured a data reduction ratio of 5:1 using a consolidated virtual server environment. Synology Hybrid RAID is not supported across all Synology NAS models and cannot be deployed on expansion units. Please check this page for more details. Peta volumes will be available later in 2021 on select models.
