How does a QNAP 4-bay NAS compare to a Synology NAS?

Comparison between QNAP 4-bay NAS and Synology NAS

Hardware Specifications

Both QNAP and Synology offer a range of 4-bay NAS models with varying hardware specifications. However, on average, QNAP NAS tends to have slightly higher processing power compared to Synology NAS. For example, the QNAP TS-453D offers a quad-core Intel Celeron processor with a clock speed of up to 2.5 GHz, while the Synology DS920+ has a quad-core Intel Celeron processor with a clock speed of up to 2.0 GHz.

Operating System

QNAP NAS devices utilize the QTS operating system, while Synology NAS devices use the DiskStation Manager (DSM) operating system. Both operating systems are user-friendly and offer a wide range of features and applications.

App Ecosystem

In terms of the app ecosystem, Synology NAS has a larger and more established community, with a wide variety of third-party applications available through the Synology Package Center. QNAP NAS also offers a decent selection of apps through the QTS App Center, although it may have fewer options compared to Synology.

Data Protection and RAID Support

QNAP NAS provides flexible RAID configurations, including RAID 0, 1, 5, 6, 10, and JBOD, allowing users to choose the level of data protection they require. Synology NAS, on the other hand, supports RAID 0, 1, 5, 6, and 10, but also offers a more advanced RAID system called SHR (Synology Hybrid RAID), which optimizes storage capacity and simplifies RAID management.


When it comes to performance, QNAP NAS generally offers better sequential read/write speeds. For example, the QNAP TS-453D can achieve sequential read speeds of up to 654 MB/s and sequential write speeds of up to 597 MB/s. The Synology DS920+ has slightly lower sequential read and write speeds, with up to 559 MB/s and 542 MB/s, respectively.


Price points for QNAP and Synology 4-bay NAS models vary depending on the specific hardware configuration and features. However, in general, Synology NAS tends to be slightly more expensive compared to QNAP NAS with similar specifications.


Both QNAP and Synology offer reliable and feature-rich NAS solutions, and the choice ultimately depends on individual requirements and preferences. If high performance and a larger app ecosystem are crucial, QNAP may be the preferred choice. On the other hand, if advanced data protection features and a user-friendly interface are more important, Synology NAS could be the better option.
