Synology DiskStation DS415+ 4-Bay 3.5" Quad Core 2.4 GHz Diskless 2xGbE NAS SMB 2 GB DDR3

Synology DS415+ 4-Bay

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 225.81 MB/s and 223.86 MB/s respectively1, while encrypted file transfers retain an astoundingly similar level of performance, exceeding 225.84 MB/s reading and 171.82 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. Whether you are a Windows or Mac user, you can back up everything on your computer directly to Synology NAS using Cloud Station. Whenever you modify a file, the changes are backed up to DS415+ automatically. Mac users also enjoy native Apple® Time Machine support. You can also back up data from your DS415+ to another DiskStation, rsync servers, external drives, or even Amazon® S3, Glacier cloud service, Microsoft Azure, SFR, and hicloud. "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.

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 private cloud easily. Cloud Station is the perfect package to sync files across multiple devices. Files can be edited in offline mode and later synced to Cloud Station, which keeps up to 32 historical versions, allowing you to restore a file back to previous version or recover deleted files. With the mobile app DS cloud, any change made to a file is automatically synced to your smartphones and tablets. For distributed enterprises, Synology's 2-way sync between different DiskStations ensures employees at different locations share the same information in real-time. IT administrators can handpick individual folders that they want to sync to different devices, manually or automatically based on file format and size. Folders synced by Cloud Station can be encrypted on DSM — no one will be able to access its content without your private key.

Secure your data

DS415+ offers advanced security measures to protect you from potential security holes. Security Advisor analyzes system settings, password strength, network preferences and removes any possible malware. AppArmor blocks malicious programs from accessing unauthorized system resources. You can also customize the trust level in Package Center to avoid installing packages from untrusted sources, safeguarding your NAS from unknown or tampered files. In addition, DS415+ provides other security add-ons, such as AES encryption, 2-Step verification, IP block & allow list, Antivirus packages, firewall, and DoS attack prevention.

Eco-friendly NAS server

All Synology NAS is designed with energy efficiency in mind. DS415+ only consumes 14.78W in HDD Hibernation and 32.64W 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.
