Synology HAT5310 20TB SATA III 3.5" Internal Enterprise HDD, 7200 RPM Speed, 512MB Cache, Up to 268 MB/s Sustained Transfer Rate, 2.5 Million Hours MTTF | HAT5310-20T

The Synology HAT5310-20T is part of the flagship Enterprise Series, designed to deliver unparalleled performance and stability within Synology NAS and IP SAN environments. Unlike generic enterprise drives, the HAT5310 is "Better Together" with Synology hardware, having undergone over 500,000 hours of rigorous validation testing to ensure maximum uptime for enterprise file servers and large-scale surveillance arrays.
 

Performance: Optimized Throughput & Persistent Cache
Equipped with a 512MB cache and a high-speed 7200 RPM spindle, the HAT5310 provides rapid access to data. A standout feature is its Persistent Write Cache Technology, which significantly reduces the risk of data corruption in the event of a sudden power loss. By optimizing the way data is handled between the DSM software and the drive's firmware, Synology enables higher sequential throughput, making it ideal for multi-user environments and high-resolution video post-production.
 

Enterprise Reliability: 550TB Workload Rating
Built to withstand the most punishing workloads, the HAT5310-20T is rated for 550TB of data transfers per year. This enterprise-class durability is supported by a 2.5 million-hour MTTF (Mean Time To Failure). Whether you are managing a petabyte-scale backup or a 24/7 mission-critical database, this drive is engineered to provide unwavering reliability.
 

Maintenance: Effortless DSM Integration
One of the key benefits of choosing Synology-branded drives is the streamlined maintenance. Users can perform one-click firmware updates directly through the DSM interface, eliminating the need to pull drives or use third-party tools. This integration also provides advanced health monitoring, ensuring that any potential issues are flagged before they can lead to downtime.
 

Why the HAT5310-20T Stands Out
Native Synology Optimization: Performance-tuned specifically for Synology NAS/Server ecosystems.

Massive 20TB Capacity: Ideal for dense storage requirements and high-capacity RAID arrays.

Helium-Sealed Design: Reduces friction and power consumption for a cooler, more efficient operation.

5-Year Limited Warranty: Backed by Synology's full enterprise support and service.
