This article covers Synology NASキット 4ベイ DS423＋ クアッドコアCPU 2GBメモリ搭載 スタンダードユーザー向け 国内正規代理店品 電話サポート対応品 DiskStation.

Overview

The Synology DiskStation DS423+ is a 4-bay NAS kit designed for home users and small offices. Powered by an Intel Celeron quad-core CPU and 2GB of RAM, this standard model lets you build a private cloud for storing photos, videos, and documents while keeping full data ownership. It supports up to 72TB of raw storage (4× 18TB drives) and delivers sequential read/write speeds of 226/224 MB/s. The compact metal chassis (223×199×166 mm) fits neatly on a desk or in a network rack. Synology's DiskStation Manager (DSM) provides a polished web-based interface with dozens of first-party apps—file sharing, backup, multimedia server, surveillance station, and more. The DS423+ strikes a practical balance between cost and capability, making it a popular entry-to-mid-range NAS for anyone who values data privacy over cloud subscription services.

Connectivity & Compatibility

Drive support: 3.5-inch SATA HDD / 2.5-inch SATA SSD (sold separately) Network: Dual 1GbE LAN ports (Link Aggregation supported) USB: 2× USB 3.2 Gen 1 ports (one front, one rear) Client OS: Windows, macOS, Linux, iOS, Android * File systems: Btrfs, EXT4 The front USB port can be used with the USB Copy button for one-touch backups from external drives. The dual Gigabit LAN ports allow link aggregation to combine bandwidth up to 2 Gbps, though real-world throughput depends on switch support and workload.

Product Info

Launched in March 2023, the DS423+ is Synology's current-gen 4-bay standard NAS. Retail price is around ¥60,000 (without drives) in Japan. The package includes a power adapter, two RJ-45 cables, and a quick-start guide. Warranty is 3 years through authorized Japanese distributors, with phone and email support available. Market positioning: solidly mid-range. The Celeron CPU and 2GB non-expandable RAM keep costs down, but DSM's advanced features—Snapshots, Hyper Backup, Surveillance Station (2 free licenses)—are fully available. If you need virtualization (VMM) or Docker containers, consider the DS723+ or DS923+ with more RAM and a faster CPU.

Best Use Cases

Family photo & video hub — Use Synology Photos to auto-backup smartphones, apply AI facial recognition, and create shared albums with per-user permissions. Works great for multi-device households. Central backup target — Active Backup for Business can back up Windows PCs, Macs, and even Hyper-V/VMware hosts. Snapshot technology protects against ransomware by retaining point-in-time copies. Small-office file server — Manage user quotas, Windows ACLs, and protocol access (SMB, AFP, FTP, WebDAV). Reliable for 20–30 concurrent users in a typical office environment. Lightweight media server — Stream photos and music to DLNA devices or use Plex Media Server (limited; 4K transcoding may struggle). Best suited for direct-play scenarios. Not recommended for heavy Docker users, 4K Plex transcoding, or virtual machine hosts—for those, step up to a plus-series model with expandable RAM and a more powerful CPU.
