Synology HAT3320 20 TB Plus Series 3.5-Inch SATA Hard Drive

Bring 20 TB of internal storage capacity to systems built around 3.5-inch SATA drive bays. This Synology Plus Series hard drive provides a large-capacity mechanical storage option for file shares, backup repositories, archive volumes, and other workloads that require substantial local disk capacity. Its standard 3.5-inch format fits the physical drive-bay format used by many NAS and storage appliances. The SATA interface places the drive in conventional internal hard-drive deployments rather than external USB storage workflows. Administrators can use the capacity for new storage pools or as part of an expansion plan where available drive bays are limited. A 20 TB drive can reduce the number of disks required to reach a target capacity, while still allowing the storage platform to determine its own redundancy, filesystem, and volume configuration. HAT3320-20T identifies the 20 TB configuration in Synology's Plus Series hard-drive range. The combination of 20 TB capacity, a 3.5-inch internal form factor, and SATA connectivity distinguishes it as a high-capacity disk option for installations that need to maximize storage density per bay. Verify that the target enclosure accepts 3.5-inch SATA hard drives and that its supported-drive policy accommodates the required capacity before installation.
