The HAT3310‑16T is a 16 TB, 3.5‑inch NAS / Plus‑Series hard drive from Synology. It belongs to the “Plus” line of drives, aimed at home, SOHO (small office/home office), and small/medium business NAS deployments. It’s built for always-on operation, with performance and reliability tuned for Synology NAS systems.

Key Features

• Reliable Always-On Operation
  Backed by 1.2 million hours MTBF and 180 TB/year workload rating.
• Tested for Maximum Reliability
  Stringent validation and up to 500,000 hours of testing ensure reliability in Synology systems.
• Seamless Firmware Updates
  Firmware updates can be performed directly in Synology DSM.
• Reliable Recording Technology
  Conventional magnetic recording (CMR) technology offers consistent performance.

• High capacity + high speed: The 16 TB size combined with 7,200 RPM and a large cache (512 MB) makes it strong for large file storage, backups, and media serving, especially where sequential read/write matters.

• NAS‑class reliability: Designed for 24/7 operation, tested to over 500,000 hours, with robust firmware and Synology integration (firmware updates via DSM).

• Good throughput: Sustained data speed (~281 MiB/s) is strong for HDDs, useful for streaming large files, serving multiple clients, or working with large datasets.

• Workload limit: 180 TB/year is significantly more than what typical desktop drives are rated for, which helps for environments with frequent writes

• Certifications / Environmental Tolerance
  It supports a fairly wide operating temperature range (5 °C to ~ 60°C) and has decent operating voltage and environmental specifications. Helps in harsh or demanding environments.

• Decent Price‑Performance (for NAS use)
  Among its peers, when priced reasonably, the combination of capacity, throughput, and NAS‑friendly features (firmware updating, reliability) tends to make it a compelling option. (Some users note it performs like competitor drives but costs less or same under some market conditions.)

Engineered for endurance

The HAT3310-16T Plus Series HDD is backed by a 1.2 million hour mean time between failures (MTBF) rating and 180 TB per year workload rating, up to three times the limit of conventional desktop hard drives. Over 500,000 hours of compatibility and stress testing ensure smooth operation even under multi-user workloads.

Convenient Firmware Updates

Users are automatically notified when firmware updates become available for the HAT3310-16T and you can update the drive seamlessly from DiskStation Manager (DSM) on your Synology storage system, eliminating the need for third-party tools and disk removal for firmware updates.
