Overview

The Synology DS923+ is a 4-bay NAS DiskStation built for users who need reliable, centralized storage with room to grow. Powered by an AMD Ryzen R1600 dual-core processor with four threads, it delivers strong throughput for file sharing, multimedia streaming, backup operations, and even lightweight virtualization. Sequential read and write speeds reach up to 625 MB/s and 559 MB/s respectively, ensuring that large file transfers across the network remain fast and efficient. Built-in M.2 NVMe SSD slots allow you to add cache drives that accelerate access to frequently used data without sacrificing any of the four main drive bays.

Scalability is a defining strength of the DS923+. Starting with four bays supporting up to 50TB of raw storage, you can expand to nine drives by attaching Synology DX517 expansion units as your data grows. The compact chassis includes a PCIe expansion slot for upgrading to 10GbE networking, ensuring the unit can keep pace with increasing bandwidth demands. Synology's DiskStation Manager operating system ties everything together with an intuitive browser-based interface, offering tools for automated backups, file synchronization, video surveillance, Docker containers, and more. With hardware encryption, snapshot-based data protection, and support for RAID configurations, the DS923+ is engineered to keep your data safe and accessible around the clock.
