This article covers Synology DS225+ 2ベイ ディスクステーション NAS (Intel Celeron J4125 クアッドコア、2GB Non.

Overview

The Synology DS225+ is a 2-bay NAS designed for home and small office data management. Powered by an Intel Celeron J4125 quad-core processor and equipped with 2GB of DDR4 Non-ECC memory (expandable up to 6GB), this bundle includes two 12TB Seagate Ironwolf drives, giving you 24TB of total raw capacity right out of the box. It is manufactured by Synology, sold and fulfilled by Amazon US (ASIN: B0FVG1KJKF).

Key Features

  • Intel Celeron J4125 Quad-Core Processor: Energy-efficient yet capable of handling file sharing, media serving, and light virtualization tasks.
  • 2GB DDR4 Non-ECC Memory (Expandable to 6GB): Smooth operation out of the box, with an open SODIMM slot for future upgrades.
  • Synology Hybrid RAID (SHR) Support: Automatically optimizes RAID levels for mixed-capacity drives, making RAID setup easy for beginners.
  • Btrfs File System with Snapshots: Self-healing file system detects and repairs corruption, while snapshots allow point-in-time data recovery.
  • Dual LAN Ports (2.5GbE + 1GbE): The 2.5GbE port accelerates large file transfers; the 1GbE port can be used for backup or management traffic.

Compatibility & Considerations

  • Drive Support: Two 3.5-inch SATA HDD/SSD bays. The bundle includes Seagate Ironwolf 12TB drives. Third-party drives are compatible with DSM 7.3 or later.
  • Memory Expansion: One DDR4 SODIMM (Non-ECC) slot is available; upgrade to 6GB total (2GB + 4GB) for better multitasking.
  • Network Requirements: For best performance, pair with a 2.5GbE switch or router. Works fine on standard 1GbE networks.
  • OS Compatibility: Windows, macOS, Linux, iOS, and Android. Remote access via Synology mobile apps (DS file, DS photo, DS video).

Who Is This For?

  • Home users wanting centralized photo/video/file storage: Automatically back up devices and access files from anywhere.
  • Small offices needing file sharing and backup: Share documents among team members and schedule PC backups.
  • Media enthusiasts: Stream movies and music to DLNA-compatible TVs and game consoles.
  • NAS beginners concerned about RAID complexity: SHR simplifies RAID setup while still providing data protection.

Setup Tips & Cautions

  • Initial Setup Requires a PC or Smartphone: Use a web browser or the Synology Assistant app to install DSM.
  • RAID Choice: For two bays, SHR (mirroring) is recommended. It protects against a single drive failure but halves usable capacity to ~12TB.
  • Backup Strategy: A NAS is not immune to failure. Consider an additional backup to cloud storage or an external drive for critical data.
  • Noise and Placement: The fan is relatively quiet but may be audible in a silent room. Place in a well-ventilated area.
