Product Description
The Synology HAT3320-8T 8TB Plus Series Hard Drive is designed for reliable storage, backup, file sharing and multi-user data workloads in compatible Synology systems.
Built for continuous 24/7 operation, the drive uses Conventional Magnetic Recording technology to provide consistent write performance in supported RAID arrays and storage pools.
Its helium-sealed design helps support efficient operation, reduced internal resistance and dependable performance in compatible Synology storage environments.
The HAT3320-8T features a SATA 6Gb/s interface, 7,200 RPM rotational speed, 512MB cache and a typical maximum sustained data-transfer speed of up to 281MB/s.
With a 300TB per year workload rating and a 1,200,000-hour MTBF rating, the drive is suited to demanding home, small-office and business storage workloads.
Synology Plus Series drives undergo more than 500,000 cumulative hours of compatibility and stress testing. Compatible firmware updates can also be installed directly through Synology DiskStation Manager without removing the drive or using third-party firmware tools.
This product is an internal 3.5-inch SATA hard drive. A Synology NAS enclosure is not included.

Compatibility Note
Please confirm that the Synology HAT3320-8T 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 HAT3320-8T 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 8TB capacity because of storage calculations, formatting, system partitions, RAID configuration and other system requirements.
Actual transfer performance depends on the Synology system, RAID configuration, network connection, workload, other installed drives and 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
