Introduction
The Synology DS718 NAS is designed for users seeking a powerful, scalable, and feature-rich network-attached storage solution. As a two-bay NAS with the potential for expansion, the DS718 offers a reliable option for small to medium-sized businesses, as well as advanced home users who need ample storage space, strong data protection, and efficient management tools. Synology is well-regarded for its intuitive DiskStation Manager (DSM) operating system, and the DS718 leverages this platform to provide a user-friendly yet sophisticated experience for data storage and management. I bought this NAS a few years ago on Amazon and there are new products such as DS723.
With a quad-core processor, real-time 4K video transcoding, and Btrfs file system for advanced data protection, the DS718 is equipped to handle a wide array of tasks, from file sharing and media streaming to data backup and even light virtualization. This review will explore the main features, advantages, and drawbacks of the Synology DS718, helping potential buyers determine if this NAS device meets their needs.
Features
Powerful Quad-Core Processor and Expandable RAM: The DS718 is powered by an Intel Celeron J3455 quad-core processor, which runs at up to 2.3 GHz, providing robust performance for multitasking and media streaming. It comes with 2GB of DDR3L RAM, expandable up to 6GB, allowing for enhanced performance in environments with heavy workloads or when running multiple applications simultaneously.
Two-Bay Setup with Expansion Capability: The DS718 has two drive bays that can accommodate up to 20TB of storage (10TB per drive). For users who need more storage in the future, it’s compatible with the DX517 expansion unit, allowing for a total of seven bays and up to 70TB of storage. This flexibility makes the DS718 suitable for growing businesses and evolving data needs.
DiskStation Manager (DSM) OS: Synology’s proprietary DSM OS is one of the most advanced NAS operating systems on the market. It provides a graphical, web-based interface for managing all aspects of the NAS, from setting up users and permissions to installing applications. DSM’s Package Center offers a broad selection of add-ons and tools, including multimedia, productivity, backup, and cloud synchronization applications.
Advanced Data Protection with Btrfs: The DS718 uses the Btrfs file system, which provides multiple layers of data protection, including snapshot and replication capabilities, data integrity checking, and file self-healing. Btrfs makes data recovery easier and offers additional security for users who store critical information on their NAS.
Real-Time 4K Video Transcoding: For media enthusiasts, the DS718 supports real-time 4K video transcoding, making it ideal for streaming high-definition media across various devices. This feature allows users to enjoy smooth playback of high-quality videos, even on devices that don’t support 4K natively.
RAID and Data Redundancy Options: The DS718 supports multiple RAID configurations, including RAID 0 and RAID 1, as well as Synology Hybrid RAID (SHR), providing flexibility in terms of performance and data protection. SHR is particularly useful for users who want the benefits of RAID without needing a deep understanding of RAID configurations.
AES-NI Hardware Encryption: Security is paramount in a NAS device, and the DS718 includes hardware-based AES-NI encryption, which helps protect data without compromising system performance. This feature is especially important for businesses that need to comply with data security regulations.
Comprehensive Backup Solutions: Synology offers a wide range of backup options for the DS718, including support for various cloud services, external drives, and network backup. DSM’s Hyper Backup and Cloud Sync applications provide flexible options for backing up and restoring data, giving users peace of mind.
Pros
Exceptional Performance: Thanks to the quad-core processor and expandable RAM, the DS718 offers fast and reliable performance, capable of handling multiple users and applications without significant slowdowns.
User-Friendly Interface: DSM is widely regarded as one of the most intuitive NAS operating systems, suitable for both novices and advanced users. The graphical interface and extensive documentation make it easy to get started.
Scalable Storage: The compatibility with the DX517 expansion unit allows the DS718 to grow with your storage needs, making it a good choice for users who want long-term scalability.
Ideal for Media Streaming: With real-time 4K video transcoding, the DS718 is an excellent media server for households or businesses that need to stream high-definition video across devices.
Data Protection and Security: Btrfs, RAID support, and AES-NI encryption provide strong data protection, making the DS718 a secure choice for sensitive information.
Rich App Ecosystem: DSM’s Package Center provides a variety of applications for backup, media streaming, file sharing, productivity, and more, making the DS718 versatile and customizable.
Cons
Higher Price Point: The DS718 is priced on the higher side for a two-bay NAS, which might be overkill for users with basic storage needs.
Limited Drive Bays in Base Model: While the expansion option adds flexibility, the two-bay design may be restrictive for users who require a high number of bays from the start.
No HDMI Output: The absence of an HDMI port limits its use as a direct media player for TVs or monitors, which may be a drawback for users looking for a fully integrated media solution.
