This article covers Synology NASキット 2ベイ DS223 クアッドコアCPU 2GBメモリ搭載 ミドルライトユーザー向け 国内正規代理店品 電話サポート対応品 DiskStation.

Overview

The Synology DS223 is a 2-bay NAS kit positioned at the entry-to-mid level, designed for home users and small offices looking to build a private cloud. Powered by a Realtek RTD1619B quad-core Cortex-A55 processor (1.7 GHz) and 2 GB of DDR4 non-expandable memory, it delivers solid file-sharing and backup performance for basic workloads. The unit ships without drives, so you'll need to purchase one or two 3.5-inch or 2.5-inch SATA HDD/SSDs separately — giving you full flexibility over capacity and redundancy. With support for up to 32 TB raw capacity (2× 16 TB drives), the DS223 runs Synology's DiskStation Manager (DSM) operating system, offering a polished web-based interface for file management, multimedia streaming, snapshot protection, and cross-platform backup. Its compact footprint (108 mm wide × 233 mm deep × 165 mm high) fits neatly on a desk or in a media cabinet.

Connectivity & Compatibility

Networking is handled by a single Gigabit Ethernet port, which is adequate for typical home/SOHO file transfers but lacks link aggregation or 2.5 GbE options. Two USB 3.2 Gen 1 ports allow connection of external storage drives or a UPS unit for safe shutdown. The drive bays support both 3.5-inch and 2.5-inch SATA drives (HDD or SSD), though hot-swap is not supported — you'll need to power off the NAS when replacing drives. File system choices include Btrfs and ext4, enabling advanced integrity checks and snapshot-based data protection. Client access is available from Windows, macOS, Linux, iOS, and Android via SMB, AFP, NFS, and Synology's mobile apps.

Product Info

The Synology DS223 launched in early 2023 as a mid-range 2-bay NAS. It sits between the entry-level DS123j and the higher-performance DS224+, offering a good balance of ease-of-use and core features without the cost of a Plus-series model. The current street price in Japan is around ¥53,800 — competitive against rivals like the QNAP TS-233. The unit comes with a 3-year warranty, and authorized Japanese distributors provide phone support. In the box you'll find the NAS, an external power adapter, a Gigabit Ethernet cable, and a quick-installation guide. Drives are not included.

Best Use Cases

Family media sharing and photo backup: With Synology Photos, you can automatically back up photos from smartphones and create shared albums for family members. It's ideal for households that want a private cloud alternative to Google Photos. The DS223 can handle basic photo thumbnailing, but don't expect real-time 4K video transcoding — that requires a Plus-series unit. Centralized file storage for multiple devices: Use the DS223 as a file server to consolidate data from PCs, Macs, and laptops. It supports Time Machine backups for macOS and File History for Windows. If you plan to store large media libraries or run daily backups, choose large-capacity drives (8 TB or more) and consider RAID 1 for redundancy — though that halves usable space. * Light SOHO file sharing: For a small team of up to 5 people, the DS223 provides reliable file serving with granular user permissions and Active Directory integration. However, its fixed 2 GB RAM and low-power CPU limit multitasking; avoid running Docker containers, VMs, or heavy surveillance station workloads on this model. If you anticipate growth, step up to the DS224+ which offers expandable memory and a more powerful processor.
