The Synology HAT5300 3.5 SATA hard drive offers 8 TB of storage capacity and is specifically designed for use in Synology NAS systems. This internal drive, with a 3.5-inch (8.9 cm) form factor and SATA 6 Gb/s interface, provides reliable data storage for home and small business network storage applications. The hard drive operates at 7200 RPM and features a 256 MB cache, enabling consistent performance for multi-user environments and data-intensive tasks. Built for continuous operation, it supports workloads of up to 180 TB per year with an average annual failure rate of 0.44 percent. The HAT5300 includes rotational vibration sensors to maintain stability in multi-drive NAS enclosures, while advanced power management features optimize energy efficiency without sacrificing performance. With support for Synology DSM operating system features such as Data Scrubbing, Bad Sector Scanning, and SMART Monitoring, this hard drive integrates seamlessly into Synology storage solutions. The 8 TB capacity provides ample space for document archives, multimedia collections, backup repositories, and collaborative work environments. Measuring 147 mm in width, 101.6 mm in depth, and 26.1 mm in height, it weighs approximately 670 g. The operating temperature range is between 5 °C and 60 °C, while the non-operating range is between -40 °C and 70 °C. The drive produces 28 dB of idle noise and 32 dB during seek operations, making it suitable for office and home environments. This successor model to earlier Synology hard drives maintains compatibility with most Synology NAS devices and offers enhanced reliability features for continuous operation scenarios.
