Synology HAT5310-20T 20TB Enterprise 3.5-Inch SATA HDD
Estimated delivery between August 10 and August 14.
The Synology HAT5310-20T is a 20TB Enterprise Series 3.5-inch SATA hard drive designed for demanding 24/7 storage in compatible Synology systems, featuring a helium-sealed CMR design, 7,200 RPM speed, 512MB buffer and sustained transfer speeds of up to 281MB/s.
Product Description
The Synology HAT5310-20T 20TB Enterprise Series Hard Drive is engineered for high-capacity storage, business backup and demanding multi-user 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 construction supports efficient and dependable operation in high-capacity storage environments.
The HAT5310-20T features a SATA 6Gb/s interface, 7,200 RPM rotational speed, 512MB buffer and a typical maximum sustained data-transfer speed of up to 281MB/s.
With a 550TB per year workload rating and a 2,500,000-hour MTBF rating, the drive is suitable for enterprise file servers, large-scale backups, surveillance recording and demanding business storage environments.
Persistent Write Cache technology helps reduce the risk of data corruption during unexpected power loss.
Synology Enterprise 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 separate firmware tools.
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 HAT5310-20T is officially compatible with your exact Synology DiskStation, RackStation or storage system before ordering.
Compatibility may vary according to the Synology system model, hardware revision, supported drive list, drive firmware and installed DSM version.
The Synology system must specifically support 20TB drives.
The HAT5310-20T 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 20TB 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.
