Overview

The Synology HAT3310-12T is a 12TB SATA hard drive engineered specifically for use in Synology NAS systems. Built around Conventional Magnetic Recording (CMR) technology, the drive avoids the write performance inconsistencies associated with SMR drives, making it well-suited for the sustained and random write patterns common in multi-user NAS environments. With a rated mean time between failures (MTBF) of 1.2 million hours and a workload rating of 180 TB per year, the HAT3310-12T is designed to handle continuous 24/7 operation without compromising data integrity or performance over time.

A key differentiator of Synology's Plus Series drives is the depth of validation and integration with Synology's ecosystem. Each drive undergoes up to 500,000 hours of compatibility testing to ensure reliable operation within Synology NAS units, and firmware updates can be deployed directly through Synology's DiskStation Manager (DSM) software — a convenience that eliminates the need for separate firmware utilities. For Synology NAS owners building or expanding their storage, the HAT3310-12T offers a tightly integrated, worry-free option backed by a 3-year warranty.

Frequently Asked Questions

While it is a standard 3.5" SATA HDD that can physically work in other NAS enclosures, it is specifically validated and optimized for Synology systems, and features like seamless DSM firmware updates are exclusive to Synology NAS units.
CMR writes data tracks side by side without overlapping, which provides consistent write performance and makes it better suited for NAS workloads than SMR (Shingled Magnetic Recording) drives, which can slow down during sustained or random write operations.
The drive is rated for 180 TB per year of data transfer, which supports demanding multi-user NAS environments with heavy read and write activity around the clock.
Firmware updates for the HAT3310-12T can be applied directly through Synology DiskStation Manager (DSM), eliminating the need for separate firmware tools or manual update procedures.
