## Long description

Synology HAT3320-20T is a 3.5" internal HDD with 20 TB capacity, 7200 RPM spindle speed and SATA III interface. Designed for NAS and server environments, it provides high-capacity storage for backups, media libraries and virtual machines, and is built for continuous 24/7 operation in multi-bay arrays and RAID configurations.
Advantages
The drive uses 100% conventional magnetic recording (CMR) to deliver consistent write performance over its lifespan. It undergoes extensive compatibility and stress testing for reliable 24/7 operation under multi-user workloads, and Synology integrates firmware and system-level optimizations to improve sequential read performance compared to similar-class third-party drives. Firmware updates can be applied directly through Synology DSM without removing disks.
Suitable for
Network-attached storage (NAS) systems in home or small to medium businesses
Multi-bay arrays and RAID configurations for redundancy and capacity
Large media libraries, backup repositories, and archive storage
Virtual machines and server workloads requiring high-capacity drives
When it may not be suitable
This 3.5" 7200 RPM SATA III drive is intended for NAS and server use and may be impractical for ultra-low-power or compact systems that require 2.5" form factor drives or lower energy consumption. It is not a replacement for SSDs where very low latency or the highest IOPS are required.
Key specifications
Form factor: 3.5 inch
Capacity: 20 TB
Interface: SATA III (6 Gbit/s)
Spin speed: 7200 RPM
Recording technology: Conventional Magnetic Recording (CMR)
Typical use: NAS / server environments with 24/7 operation
Weight: approximately 730 g
How to use
Install the drive into a compatible 3.5" bay in your NAS or server following the device manufacturer's instructions. Configure the drive within the NAS operating system (Synology DSM or other supported OS) to join an existing array or create a new volume. Apply firmware updates via the NAS management interface when available to ensure compatibility and receive performance and reliability patches.
What to consider before purchase
Verify your NAS or server supports 3.5" SATA III drives and 7200 RPM operation
Ensure your enclosure and RAID configuration meet cooling and vibration requirements for multi-bay arrays
Consider whether SSDs are preferable for workloads needing very low latency or high IOPS
Confirm available drive bays and total capacity planning for redundancy and future growth
Usage recommendations
For best long-term reliability, use these drives in NAS systems with proper cooling, maintain RAID redundancy for critical data, and perform firmware updates via DSM to benefit from Synology's optimizations and patches.
