Quad-core 4-bay NAS optimized for intensive tasks and encryption
Designed for small and medium-sized businesses, DS415+ delivers outstanding performance, accelerated hardware encryption, and ample storage capacity – satisfying the growing need for both speed and security.

High-speed data transfer and hardware encryption engine
Equipped with a quad-core processor and AES-NI hardware encryption engine, DS415+ delivers blazingly fast file transfer speeds – even when handling encrypted data. With Link Aggregation enabled, DS415+ delivers average reading and writing speeds of 228 MB/s and 233 MB/s respec­tively1, while encrypted file transfers retain an astoundingly similar level of performance, exceeding 232 MB/s reading and 206 MB/s writing. That means you can safeguard data without sacrificing performance.

Dual LAN ports for failover and Link Aggregation support
Equipped with two Ethernet ports featuring failover and Link Aggregation support, DS415+ ensures continual network uptime even if LAN connection malfunction occurs on one port, reducing the chance of service disruption and costly downtime. Link Aggregation improves connection speeds beyond the limits of a single network cable or port.

Easy installation, hassle-free maintenance
Easy installation and hot-swappable hard drive support ensures easy maintenance and continuous service uptime should a hard drive need replacement. In addition, DS415+ incorporates a passive cooling design to reduce dependency on the dedicated processor cooling fan, thus mitigating any critical point of failure. When the system detects a fan failure, the built-in redundancy mechanism ensures continuous operation until the replacement fan arrives.

USB 3.0 and eSATA ensure speedy transfers to external storage
DS415+ boasts USB 3.0, USB 2.0, and eSATA 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. Synology's Package Center lets you download and install useful add-on packages designed specifically for individual or business needs, meaning you can enjoy more entertainment in your life or better productivity at work.

Seamless storage solution for virtualization environments
DS415+ provides seamless storage solutions for virtualization environments, including VMware, Citrix, and Microsoft Hyper-V. With VMware vSphere 5 & VAAI integration, DS415+ helps offload specific storage operations and optimizes computation power in VMware environments. Windows ODX support speeds up data manipulation as the data transfer is offloaded. iSCSI also lets SMB users consolidate storage into data center storage arrays while providing hosts with the illusion of locally-attached disks.

Fit into business environments easily
With the support of Windows AD, LDAP, and Domain Trust, DS415+ enables seamless account integration. The User Home feature can automatically create a “home” folder for every user account to minimize the administrator's ef­fort in repeatedly creating “home” folders for all accounts. Windows ACL support on DS415+ allows IT administrators to fine tune access controls and set up privileges to files and folders on DS415+ through the familiar Windows user interface. With compatibility for major protocols, DS415+ can eliminate server configuration overhead and enhance IT administrators' efficiency.

Optimize storage management
With Synology's Storage Manager, DS415+ allows for flexible storage deployment and utilization. You can optimize RAID configuration with Synology Hybrid RAID (SHR) while providing redundant data protection. Other features such as multiple volumes on single RAID and Global Hot Spare also greatly enhance management efficiency and fit deployment of any kind.

The most compatible sharing
Enjoy seamless files sharing across Windows, Mac, and Linux platforms as DS415+ offers comprehensive network protocol support including FTP, SMB2, AFP, NFS and WebDAV. With Windows AD and LDAP integration, DS415+ 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.

Effective backup solution
Synology DS415+ can serve as a centralized backup target. PC users can back up their data to the DS415+ using Windows Backup, while Mac OS X users enjoy native Apple Time Machine integration. You can also back up data and applications from your DS415+ to another DiskStation, rsync servers, external drives, or even Amazon S3 and Glacier cloud service. “Backup & Replication” allows you to schedule backup tasks and restore the server to any particular point in time, while minimizing storage consumption and processing time by saving only the specific data block that has been changed between versions. With Cloud Station, files on your PC can be backed up to DS415+. Whenever you modify a file, the changes are backed up on DS415+ automatically.

All-in-One server
Offering rich office applications, DS415+ can serve as your multi-function server. With add-on packages Mail Server and Mail Station, DS415+ can become a dedicated mail server, and let you enjoy complete webmail service. DS415+ can become a VPN server or VPN client. The comprehensive VPN service let you access resources remotely while maintaining security protocols. As a printer server, DS415+ minimizes businesses' operating costs by sharing printing resources throughout the office. Administration and network tools, such as DNS Server, Directory Server, RADIUS Server, DHCP Server, and Log Center help you manage IT deployment and policies more efficiently. Maximize resource utilization with DS415+!

Ensuring business continuity
Uninterrupted availability is a critical goal for all businesses. DS415+ supports Synology High Availability (SHA) technology which combines an active and passive server into one cluster, the former always mirrored to the latter. The Heartbeat mechanism detects regular “heartbeats” between the two servers. If the main server encounters unexpected downtime, the passive server immediately takes over. With multiple LAN ports, DS415+ also ensures redundancy in the event of unexpected network failure.

Increase business productivity with cloud solutions
With comprehensive cloud solutions, DS415+ lets you create your own cloud easily. Cloud Station is the perfect package to sync files across multiple devices with the benefit of better privacy for important data. Files can be edited in offline mode and later synced to Cloud Station, which retains up to 32 versions to avoid file overwriting. With mobile app DS cloud, any change made to a file is automatically synced to your smartphones and tablets. For distributed enterprise, Synology's 2-way sync between different DiskStations ensures employees at different locations share the same information in real-time. IT administrators can customize synchronization rules, such as avoiding syncing large files to optimize bandwidth usage.

Secure your data
DS415+ provides share-level AES 256-bit encryption to block off unauthorized access attempts. Once you create and encrypt a shared folder, people without the encryption key will not be able to use the encrypted data even if they remove the hard drives from your DS415+ and mount it on their device. 2-Step verification gives an extra layer of protection as 6-digit one-time code sending to your mobile device is required for login. In addition, DS415+ provides other security add-ons, such as IP block & allow list, Antivirus packages, firewall, and DoS attack prevention. These enhancements ensures a secure DSM environment.

Eco-friendly NAS server
All Synology NAS is designed with energy efficiency in mind. DS415+ only consumes 17.3W in HDD Hibernation and 46.2W in access. The support of Wake on LAN/WAN and scheduled power on and off can further reduce power consumption and operation cost. Synology acknowledges the responsibility as a global citizen, so all Synology products are produced with RoHS compliant parts and packed with recyclable packing materials.
