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.
