Overview

The Synology DS423 4-Bay NAS bundle takes the guesswork out of building a network-attached storage system by pairing a proven 4-bay DiskStation enclosure with four Synology HAT3300-6T hard drives. Together, the package delivers 24TB of raw storage capacity right out of the box—enough for centralized file sharing, automated backups, media streaming, or surveillance recording. Because the drives are Synology's own Plus Series SATA HDDs, they're validated for compatibility with DiskStation hardware, reducing the risk of firmware or performance mismatches that can occur with third-party drives.

Once assembled, the DS423 runs Synology's DiskStation Manager operating system, which provides an intuitive browser-based interface for creating storage pools, managing user permissions, installing packages like Synology Drive or Hyper Backup, and monitoring system health. The four bays support a range of RAID configurations—RAID 5 being the most popular choice here, offering roughly 18TB of usable space while tolerating a single drive failure. For users who prioritize raw capacity over redundancy, RAID 0 or JBOD are also available. The bundle is best suited for home power users, small offices, or creative professionals who need a dependable, always-on storage appliance without sourcing components individually.

Pros & Cons

👍 Pros

All four drives are matched Synology-brand units, ensuring compatibility and consistent performance
24TB raw capacity out of the box with no additional drive purchases needed
Synology's DSM operating system provides a polished, full-featured management interface
Bundle pricing simplifies purchasing versus buying the NAS and drives separately
4-bay design supports RAID 5 for a good balance of capacity and data protection

👎 Cons

16GB of RAM is not mentioned, and the base DS423 may require a memory upgrade for heavier workloads
6TB per drive is modest; users needing more total capacity may outgrow this configuration quickly
The NAS and drives ship unassembled, requiring initial setup and RAID configuration
No SSD cache drives are included, which would improve random read/write performance

Frequently Asked Questions

Does the DS423 bundle come with the drives already installed?

No, the four HAT3300-6T drives are included but not pre-installed. You'll need to insert them into the drive bays and configure your storage pool through Synology's DiskStation Manager (DSM) software.

What RAID configurations does the DS423 support with four drives?

The DS423 supports SHR (Synology Hybrid RAID), RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, and JBOD. With four 6TB drives, RAID 5 gives you roughly 18TB of usable space with single-drive fault tolerance.

Are the included HAT3300 drives designed for NAS use?

Yes, the Synology HAT3300 Plus Series drives are specifically engineered for always-on NAS environments, with workload ratings and reliability features suited for continuous operation.

Can I expand storage beyond the four included bays?

The DS423 is a 4-bay unit, so the internal bays are filled with this bundle. However, Synology NAS units support expansion via compatible DX expansion units connected over eSATA, if the model supports it.

Does this bundle include a warranty?

The Synology DS423 NAS typically carries Synology's standard hardware warranty, and the HAT3300 drives carry their own separate warranty. Check with the seller for specific coverage details.
