Compatibility Note

Please confirm that the Synology HAT3300-4T is listed as compatible with your specific 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.

This is an internal 3.5-inch SATA hard drive and requires a compatible SATA drive bay. It is not an external USB hard drive.

The available capacity displayed by your NAS or operating system will be lower than the stated 4TB capacity because of formatting, storage calculations, system files, RAID configuration and other system requirements.

Actual transfer performance depends on the Synology system, RAID configuration, network connection, workload, settings and other installed drives.

MTBF is a statistical reliability value and is not a guarantee or estimate of the operating life of an individual hard drive.
