Superior Performance for Synology Systems
Through extensive testing and firmware optimisations, the HAT5320-4T has been fine-tuned to deliver exceptional performance in demanding multi-user environments. The drive features a 7200 RPM rotational speed, 512MB cache, and SATA 6 Gb/s interface, ensuring rapid data access and uninterrupted transfers with sustained speeds up to 281 MB/s. When configured in RAID arrays with Synology NAS systems, these drives deliver up to 27% faster RAID recovery speeds compared to similar-class drives from other manufacturers.
Built for 24/7 Enterprise Workloads
The HAT5320-4T is engineered for the most demanding storage environments. With a workload rating of 550TB per year and an industry-leading 2 million hour Mean Time Between Failure (MTBF), this drive is designed to handle continuous operation in enterprise file servers, large-scale video surveillance systems, and multimedia post-production workflows. The air-filled drive design with 512e sector size ensures consistent performance and reliability across a wide range of applications.
Simplified Maintenance with One-Click Firmware Updates
Unlike third-party drives requiring complex command-line operations, the HAT5320-4T features one-click firmware updates directly through Synology's DiskStation Manager (DSM). This user-friendly update process reduces maintenance time from over 50 minutes to just a few minutes per system, with automatic notifications when updates are available. Firmware and DSM updates are delivered together, minimising the need for additional maintenance sessions and reducing the chance of oversights.
Wide Operating Temperature Range
Built to withstand demanding environmental conditions, the HAT5320-4T operates reliably in temperatures from 5°C to 60°C (41°F to 140°F), with non-operating storage tolerance from -40°C to 70°C. The drive's robust design includes shock and vibration resistance, ensuring continuous operation even in challenging deployment environments.
Power Efficiency
Despite its enterprise-grade performance, the HAT5320-4T maintains efficient power consumption with 3.49W idle power and 7.29W average operating power. This efficiency helps reduce operational costs in large-scale deployments while maintaining 24/7 availability.
Perfect for Australian Businesses
Whether you're building a video surveillance system for commercial properties, a media production workflow for creative agencies, or a centralised file server for enterprise environments, the Synology HAT5320-4T delivers the performance, reliability, and seamless integration Australian businesses demand. Compatible with Synology's extensive NAS and IP SAN lineup, this drive ensures your critical data is protected 24/7.
