Overview

The Synology HAT3310-8T is an 8TB 3.5-inch SATA hard drive from Synology's Plus Series, purpose-built for continuous operation in Synology NAS systems. Unlike generic NAS drives, this model undergoes Synology's own validation process, which includes extensive testing against Synology hardware and DiskStation Manager (DSM) software. The result is a drive designed to integrate seamlessly into Synology environments, minimizing the firmware conflicts and compatibility quirks that can sometimes arise with third-party drives.

Under the hood, the HAT3310-8T uses Conventional Magnetic Recording (CMR) rather than Shingled Magnetic Recording (SMR), which matters for NAS workloads where random writes and RAID rebuilds demand consistent performance. The 7200 RPM spindle speed provides faster sequential and random access compared to slower NAS drives, and the 1.2 million-hour MTBF rating reflects engineering focused on 24/7 uptime. With a 180 TB/year workload rating, this drive is equipped to handle the sustained read/write demands of multi-user file serving, surveillance recording, or media streaming in small to mid-sized NAS deployments.

Frequently Asked Questions

While the HAT3310-8T uses a standard SATA interface and will physically work in other NAS enclosures, it is specifically validated and optimized for Synology systems. Compatibility with other brands is not guaranteed by Synology.
CMR (Conventional Magnetic Recording) writes data tracks without overlapping, which delivers more consistent write performance and better reliability for NAS workloads compared to SMR (Shingled Magnetic Recording) drives.
The 180 TB/year workload rating defines the amount of data that can be read and written annually within warranty terms. For most home and small office NAS use cases, this is more than sufficient.
Synology runs its Plus Series drives through extended compatibility and stress testing on its own hardware and DSM software, aiming to reduce the risk of firmware-level incompatibilities and unexpected drive behavior in Synology NAS units.
The Synology HAT3310-8T includes a 3-year limited warranty from Synology.
