Secure Mounting Solutions for Storage Drives

Synology caddies are purpose-built trays designed to hold hard drives or SSDs securely within your NAS system. These components ensure each drive aligns properly with backplane connectors and remains physically stable during operation. Whether you're expanding capacity or replacing a disk, having the correct caddy is essential to maintaining performance and data integrity.

HDD and SSD Caddy Options

Synology offers both 3.5-inch HDD and 2.5-inch SSD caddies to support different drive formats. HDD caddies typically feature airflow slots and anti-vibration pads, while SSD caddies may include special brackets for precise mounting. Using the right caddy for your drive type ensures optimal cooling and reliable operation, especially in multi-bay configurations.

These trays are model-specific. Variations in dimensions, rail systems, and locking mechanisms mean caddies from one NAS series may not fit another. Verifying your NAS model ensures compatibility and prevents costly delays or mismatches during upgrades.

Enhanced Functionality with Compatible Accessories

Quality caddies play a key role in airflow, system noise reduction, and quick drive access. In high-availability environments, keeping spare caddies on hand allows for rapid drive swaps with minimal downtime. Refurbished options are also available, offering reliable performance at a lower cost for budget-conscious deployments.

When building or maintaining your NAS infrastructure, supporting accessories like Synology Cable ensure stable drive communication, while a Synology Rack Mount Kit provides secure rack installation for your caddy-equipped system.

Choosing the Right Caddy for Your NAS

Drive trays may seem like minor components, but their role in maintaining performance and physical security is critical. Poor-quality or mismatched caddies can cause misalignment, vibration, or even drive failure. By selecting a tray engineered for your specific NAS model, you preserve the long-term health of your system and the safety of your data.

Whether expanding your NAS or replacing a failed tray, Synology is essential to ensuring a reliable and scalable storage environment.
