How to install Synology HAT5300-16T

Installing a 3.5-inch internal HDD in a Synology NAS is straightforward and designed for quick upgrades with minimal downtime. Follow these steps to add the HAT5300-16T to a supported Synology system:

• Power down the NAS and unplug it from the power source. If the device supports hot-swapping, refer to the user manual for hot-swap guidance.
• Open the drive bay or remove the existing drive tray according to the NAS model’s instructions. Ensure the system is safely powered down before touching internal components.
• Attach the HAT5300-16T to the drive tray using the provided screws or tool-less mounting mechanism. Align the SATA data and power connectors with the backplane, and secure the drive firmly in place.
• Slide the drive tray back into the NAS until it clicks into the backplane, then reseat any latching mechanisms to secure the tray.
• Reconnect power and network cables, then power on the NAS. The DSM software will detect the new drive and prompt you to initialize it.
• Open DSM, go to Storage Manager, and create a new storage pool or extend an existing one. Choose your preferred RAID or SHR configuration, allocate the volume, and set up data protection options such as snapshots and replication as needed.
• Run a SMART check and monitor the drive health through DSM’s storage health tools. Consider performing a quick format if prompted, and verify data accessibility by creating a test file.

Frequently asked questions

• Is the HAT5300-16T compatible with all Synology NAS models? The HAT5300-16T is designed for compatibility with a broad range of Synology NAS systems that support 3.5-inch internal drives and standard SATA interfaces. Always verify support for hot-swapping, drive tray, and RAID features with your specific NAS model and DSM version.
• What kind of workloads is this drive best suited for? The drive excels in NAS-centric workloads such as large-scale backups, media libraries, virtualization staging, file sharing for teams, and archival storage. Its 16 TB capacity and enterprise-grade design help sustain steady performance under continuous operation.
• Can I mix HAT5300-16T with other drives in the same array? You can mix drives in a RAID/SHR configuration, but for optimal performance and reliability, Synology recommends using drives of the same model and capacity within a given storage pool. This minimizes rebuild times and ensures uniform performance.
• What warranty and support are included? The HAT5300-16T carries a lengthy warranty typical of enterprise HDDs (commonly 5 years) with access to Synology and drive manufacturer support channels for hardware replacement and diagnostics.
• How does this drive affect NAS energy use? With efficient thermal management and a design tuned for continuous operation, the drive helps maintain steady performance while keeping power consumption manageable in always-on NAS deployments.
• Is data integrity maintained during drive failures? Synology DSM leverages redundancy schemes (RAID/SHR) and snapshot-based protection to minimize data loss during drive failures, and the HAT5300-16T is built to sustain reliability during long-term operation.
