This article covers Synology NASキット 2ベイ DS223j クアッドコアCPU搭載 1GBメモリ搭載 ライトユーザー向け 国内正規代理店フィールドレイク取扱品 電話サポート対応品 DiskStation.

Overview

The Synology DS223j is a 2-bay NAS designed for home users and small offices looking to set up a private cloud easily. It's an entry-level model that excels at centralizing data from multiple devices and providing remote access. Powered by a Realtek RTD1619B quad-core processor and 1GB of RAM, the DS223j supports up to 36TB of raw storage (two 18TB drives). It runs Synology's mature DiskStation Manager (DSM) operating system, offering a polished experience for file sharing, backup, and media streaming.

Connectivity & Compatibility

On the back panel, you get a single Gigabit Ethernet port (1Gbps) and two USB 3.2 Gen1 ports for attaching external drives. The front has a USB copy button for quick imports. The DS223j accepts 3.5-inch and 2.5-inch SATA HDDs/SSDs (6Gbps). With two drive bays, you can set up RAID 1 (mirroring) for data redundancy, RAID 0 for speed, or JBOD/RAID 0 for maximum capacity. QuickConnect allows remote access without complex router configuration.

Product Info

Released in June 2023, the DS223j sits at the entry-level tier of Synology's NAS lineup. Pricing is around ¥35,000–¥40,000 in Japan, making it competitive with other budget 2-bay NAS from QNAP (TS-233) and Asustor (AS1102T). Warranty is 2 years when purchased from an authorized Japanese distributor (Fieldlake), and phone support is included. The box contains only the power adapter, a LAN cable, and a quick start guide; you must purchase HDDs separately.

Best Use Cases

Home users wanting a central file repository: If you have photos, documents, and videos scattered across phones, laptops, and tablets, the DS223j brings them together. DSM apps let you access everything on the go. Not suitable for heavy database workloads. Users seeking automated backups: Back up Windows/Mac folders to the NAS automatically via Synology Drive. The Hyper Backup utility can then back up the NAS itself to another location. RAID 1 protects against single HDD failure. * Light media server enthusiasts: With DLNA and Plex (via DSM package), you can stream music and videos to smart TVs or mobile devices. But the processor lacks hardware transcoding for 4K video, so avoid real-time transcoding. The DS223j consumes only about 10W idle, making it cost-effective for 24/7 operation. However, it lacks ECC RAM, PCIe expansion, and 10GbE networking. If you need those features, consider the DS224+ or DS723+ instead.
