Synology DS223J vs DiskStation DS124: Which NAS Should You Choose?

Design and Build Quality

The Synology DS223J features a compact 2-bay design, allowing for greater flexibility in storage configurations with support for RAID 0, RAID 1, and JBOD setups. This versatility is particularly beneficial for users seeking redundancy or increased performance. In contrast, the DS124, with its single-bay design, is more limited in configuration but offers a sleeker profile, making it ideal for small spaces. The build quality of both units is solid, with a focus on user-friendly setups, but the DS223J's dual-bay design inherently offers more potential for future expansion.

Performance

In terms of performance, the DS223J is equipped with a dual-core CPU and 2GB of RAM, which is suitable for handling multiple tasks such as file sharing and media streaming simultaneously. It provides a maximum sequential read speed of up to 225 MB/s, making it a robust choice for users with demanding needs. The DS124, however, features a quad-core CPU with the same 2GB of RAM but has a maximum read speed of around 112 MB/s. While the DS124 performs adequately for basic usage such as personal cloud storage, it lags behind the DS223J in more intensive applications like Plex media streaming or running virtual machines.

Storage Capacity and Expandability

With the DS223J supporting two drives, users can create a larger overall storage capacity, especially when using larger drive sizes. This model can support up to 32TB of raw storage using two 16TB drives, making it ideal for users with large media collections. The DS124, on the other hand, supports only one drive, limiting its capacity to 16TB at most. For growing collections or businesses that may require additional storage in the future, the DS223J is clearly the superior choice.

User Experience and Software Integration

Both models run on Synology's DiskStation Manager (DSM), which is widely praised for its intuitive interface and extensive features. However, the DS223J's additional resources enable it to run more applications smoothly, enhancing the overall user experience. Users seeking to leverage Docker or run more complex applications will find the DS223J more capable. Furthermore, the DS223J’s dual-bay design allows for easy data redundancy, ensuring that user data is better protected against drive failures.

Price and Value for Money

The DS223J is priced at £179.97, while the DS124 is available for £134.97. The price difference of £45 reflects the enhanced capabilities of the DS223J. For users who require more than basic functionality, investing in the DS223J is justified by its performance and expandability. However, for those who only need a basic NAS for file storage and light media streaming, the DS124 offers good value for money.

Conclusion

In summary, if your needs include robust performance, greater storage capacity, and the ability to run multiple applications, the Synology DS223J is the clear winner. Its dual-bay design allows for better data protection and future expansion, making it a more versatile choice for both home and small business environments. The DS124, while a solid single-bay NAS, is best suited for users with minimal storage needs and limited usage scenarios. Choosing between these two models ultimately depends on your specific requirements and future growth expectations.
