This article covers Synology DS223j 2ベイディスクステーションNAS (Realtek RTD1619B 4コア 1.7 GHz 1GB DDR4 Ram 1xRJ-45 1GbE LAN-Port) 16TB バンドル 8TB Seagate IronWolf 2個付き.

Overview

The Synology DS223j is an entry-level 2-bay NAS designed for home users and small offices. It is powered by a Realtek RTD1619B quad-core processor clocked at 1.7GHz, paired with 1GB of non-ECC DDR4 memory. The metal chassis keeps the unit compact yet sturdy. This model excels at centralizing photos and documents, enabling file sharing across multiple devices, and providing an intuitive experience through Synology's DiskStation Manager (DSM) operating system. It is an ideal choice for anyone looking to build a private cloud without breaking the bank.

Connectivity & Compatibility

The rear panel features one RJ-45 1GbE LAN port and two USB 3.2 Gen 1 ports. You can connect external HDDs or USB flash drives for additional backup destinations. The NAS supports standard 3.5-inch SATA drives, and a bundled model with two 8TB Seagate IronWolf drives (16TB total) is available. Network access works seamlessly with Windows, macOS, and Linux. Synology's mobile apps (DS file, DS photo, etc.) allow you to browse files from smartphones and tablets. The device also supports DLNA media streaming and can act as a VPN server.

Product Info

Released in mid-2023, the DS223j carries a standalone price around ¥30,000–¥35,000. The 16TB bundle reviewed here (8TB Seagate IronWolf ×2) is priced at approximately ¥257,942. The standard warranty is two years. Included accessories are a power adapter, a LAN cable, and a quick installation guide. Market positioning is firmly entry-level. With only two drive bays and a single 1GbE port, it is not suited for heavy multimedia editing or large-scale virtualization. However, it delivers reliable file-serving performance for everyday home use.

Best Use Cases

Family photo and video sharing: DSM's Photo Station automatically backs up smartphone photos and lets you create shared albums. Note that 4K video transcoding is not supported, so this NAS is not ideal for video editing workflows. Remote worker file server: Centralize documents and project files for access from multiple PCs. Snapshot and versioning features protect against accidental deletions. Best suited for small teams of up to five concurrent users; performance degrades with more simultaneous connections. * First-time NAS buyer: Setup is guided by DSM's wizard, and mobile apps are well-designed. Beginners can get started quickly. However, plan your RAID configuration and backup strategy upfront, as changing them later can be cumbersome.

Things to Consider

The most significant limitation is the 1GB of RAM. Running many DSM packages simultaneously can lead to sluggish performance. Docker and Virtual Machine Manager are not supported, so if you need those features, consider the DS224+ or higher. Networking is limited to a single 1GbE port — no 2.5GbE or Link Aggregation. Frequent transfers of large files may become a bottleneck. Also, the bundled Seagate IronWolf drives are CMR but not the Pro series, so their endurance under heavy workloads is moderate. ## FAQ
Q: Can the DS223j run a Plex server? A: Yes, but transcoding is software-based. Real-time 4K HDR transcoding is not feasible; direct play on compatible clients is recommended. Q: Can I replace the bundled HDDs? A: Yes, standard 3.5-inch SATA drives are swappable. The bundle typically comes pre-configured in RAID 1 (mirroring), so back up your data before swapping. Q: Can I use an external USB drive for backup? A: Absolutely. Connect an external HDD via USB 3.2 Gen 1 and use DSM's Hyper Backup to create backups of the internal volume.
