Ideal Companion for Your Own Cloud

Synology DS418j is a powerful entry-level 4-bay network attached storage solution equipped with a 64-bit dual-core 1.4 GHz processor and 1GB RAM, delivering sequential reading throughput at over 112 MB/s and writing throughput at over 108 MB/s, and an encrypted sequential data transmission at over 112 MB/s reading and 87 MB/s writing1. The great combination of the 64-bit hardware and DiskStation Manager (DSM) allows DS418j to take advantage of large-capacity HDDs for flexible storage volume management as well as efficient file sharing and data backup.

Cross-Platform File Sharing and Data Synchronization

Synology DS418j supports comprehensive network protocols, ensuring a seamless file sharing experience across Windows, Mac, and Linux platforms. Windows AD and LDAP integration allows DS418j to fit quickly and effortlessly into any existing network environment without the necessity to recreate user accounts. Cloud Sync keeps your Dropbox, Google Drive, Microsoft OneDrive, Baidu Cloud, and Box storages in sync with your personal DiskStation at home. The Cloud Station Suite enables you to sync files among multiple devices — Windows PC, Mac, Linux, iOS or Android tablets/ phones — easily keeping everything up-to-date. All the seamless file sharing over the Internet is protected at a high security level with the HTTPS, firewall, and IP auto-block mechanisms supported by DS418j.

Easy Backup Solutions

With block-level incremental backup and cross-version deduplication, Synology Hyper Backup provides multi-version backup with optimized storage utilization and allows data backup to multiple destinations - local shared folders, external hard drives, network shared folders, rsync servers, and public cloud services.

24/7 Security Solution

Synology Surveillance Station offers a centralized interface to manage IP cameras deployed in your workplace, allowing users traveling miles away to safeguard their environments by watching live views, recording events, and taking snapshots with computers or mobile devices. DS418j is an ideal surveillance solution as it is capable of hosting up to 16 IP cameras (480FPS at 720p). In addition to its intuitive setup and hassle-free interface, Surveillance Station features an optimized live view experience with on-screen operations, smart analytic tools like motion detection, and an alert system that sends instant notification through DS cam, SMS, and e-mail.

Synology provides mobile applications that allow you to enjoy the full variety of your multimedia library over the Internet on the go. Available on iOS, Android and Windows Phone platforms, DS photo, DS audio, DS video and DS file mobilize your Photo Station, Audio Station, Video Station and File Station by placing terabytes of multimedia content at your fingertips. What’s more, DS get makes it possible for you to manage and monitor your download tasks remotely anywhere, anytime.

Energy Efficient with Cool and Quiet Design

Synology DS418j is designed with energy efficiency in mind. Compared with its average PC counterpart, Synology DS418j consumes relatively little power at 21.22 watts while accessing and 8.97 watts when hard drive hibernation is enabled. The scheduled power on/off feature further reduces power consumption and operation cost.

Features:

Synology Hybrid RAID (SHR) technology

Storage management is easy with Synology Hybrid RAID (SHR) technology. SHR is an automated RAID management system allowing you to easily create and expand storage volumes and migrate RAID types without requiring details on RAID. SHR provides 1 to 2-disk redundancy to safeguard your data during drive failures.

• Cost-effective
  SHR maximizes the data capacity of your RAID when different sizes of HDDs are used.
• Easy Management
  For novice users who have no technical background and still want to protect their data using RAID technology, a convenient installation wizard will guide you through all the steps during your first installation.
• Scalability
  You can add new disks on the fly in Storage Manager with a simple click.
• Flexibility
  While creating a volume, you can plan ahead and leave empty and unallocated space for future usage.

Easy file access with QuickConnect

Access files on your Synology NAS over the Internet without the hassle of setting up port forwarding rules, DDNS, or other complicated network settings. QuickConnect allows you to connect via a simple customizable address (e.g. https://customID.quickconnect.to), so that you can instantly access media and work files on any Windows/Mac/Linux computer, laptop, or mobile device without additional charge.

Seamless integration with your devices

Synology mobile applications are designed to allow quick and secure access to your data wherever you are.
