Compatibility Note
Please confirm that the Synology HAT3300-4T is officially compatible with your exact Synology NAS or storage system before ordering.
Compatibility may vary according to the Synology system model, hardware revision, supported drive list and installed DSM version.
The HAT3300-4T is an internal 3.5-inch SATA hard drive and requires a compatible SATA drive bay.
It is not an external USB hard drive, portable storage device, solid-state drive or complete NAS system.
The available capacity displayed by Synology DSM will be lower than the stated 4TB capacity because of storage calculations, formatting, system partitions, RAID configuration and other system requirements.
Actual transfer performance depends on:
• Synology system model
• RAID configuration
• Network connection
• File size and workload
• Other installed drives
• Active DSM applications
MTBF is a statistical reliability measurement and is not a guarantee or estimate of the operating life of an individual hard drive.
RAID helps protect against selected drive failures but does not replace an independent backup.
Installation Guidance
Before installation:
• Confirm compatibility with the Synology system
• Back up important existing data
• Use suitable anti-static precautions
• Handle the drive by its sides
• Secure the drive correctly in the drive tray
• Follow the Synology hardware-installation guide
After installation:
• Confirm the drive is detected in DSM
• Check the drive-health status
• Apply supported firmware updates
• Configure or expand the storage pool
• Allow initialisation or repair operations to complete
• Maintain an independent backup
Do not remove the drive during RAID repair, storage-pool expansion, data scrubbing, firmware updates or other critical storage operations.
