Synology HAT5320-24T 24TB Enterprise 3.5-Inch SATA HDD

The Synology HAT5320-24T is a 24TB Enterprise Series 3.5-inch SATA hard drive designed for demanding 24/7 storage in compatible Synology systems, featuring CMR technology, a helium-sealed design, 7,200 RPM speed, 1GB buffer and typical sustained transfer speeds of up to 309MB/s.

Product Description

The Synology HAT5320-24T 24TB Enterprise Series Hard Drive is engineered for demanding, high-capacity storage workloads in compatible Synology NAS and enterprise storage systems.

Designed for continuous 24/7 operation, the drive uses Conventional Magnetic Recording technology to deliver consistent write performance in supported RAID arrays and storage pools.

Its helium-sealed construction supports reliable and efficient operation in high-capacity storage environments.

The HAT5320-24T features a SATA 6Gb/s interface, 7,200 RPM rotational speed, 1GB buffer and a typical maximum sustained data-transfer speed of up to 309MB/s.

With a 550TB per year workload rating and a 2,500,000-hour MTBF rating, the drive is suitable for enterprise file storage, large-scale backups, surveillance recording, multimedia production and demanding multi-user environments.

Persistent Write Cache technology helps reduce the risk of data corruption during unexpected power loss. Synology Enterprise Series drives also undergo more than 500,000 cumulative hours of compatibility and stress testing.

Compatible firmware updates can be installed directly through Synology DiskStation Manager, helping simplify drive maintenance without requiring drive removal or separate firmware tools.

This product is an internal 3.5-inch SATA hard drive. A Synology NAS or storage enclosure is not included.

Specifications

Compatibility Note

Please confirm that the Synology HAT5320-24T 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 HAT5320-24T 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 24TB 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
• Confirm that the system supports 24TB drives
• Back up important existing data
• Use suitable anti-static precautions
• Handle the drive by its sides
• Avoid touching the SATA connector or circuit board
• 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.

What’s in the Box

• 1 × Synology HAT5320-24T 24TB Enterprise Series 3.5-Inch SATA Hard Drive

Sustainability

The Synology HAT5320-24T is RoHS compliant.

Compatible firmware updates can be managed through Synology DSM without removing the drive or connecting it to separate firmware equipment.

The drive should be recycled through an appropriate electronic-waste recycling facility at the end of its usable life.
