Synology HAT5320-24T 24TB 3.5-inch SATA Enterprise NAS HDD

The Synology HAT5320-24T is a 24TB Enterprise Series 3.5-inch SATA hard drive designed for demanding 24/7 storage workloads in compatible Synology systems. It features a helium-sealed CMR design, 7,200 RPM rotational 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 provide consistent write performance. Its helium-sealed construction supports reliable and efficient operation in high-capacity storage arrays.

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 2.5 million-hour MTBF rating, the drive is suitable for enterprise file servers, large-scale backups, video surveillance, 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.

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

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

Compatibility Note

Please confirm that the Synology HAT5320-24T 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 24TB 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.
