Capacity and purpose

The Synology HAT3310-16T is a 16TB 3.5-inch internal hard drive designed for NAS systems. It operates at 7200 RPM with a 512MB cache and uses a SATA 6.0Gb/s interface. This drive targets users who need high-capacity, always-on storage for network-attached environments.

Sustained load behaviour

The drive is rated for a 180 TB per year workload and backed by a 1.2 million hour MTBF. Validation includes over 500,000 hours of testing to ensure reliability in continuous operation. Conventional magnetic recording technology provides consistent performance during extended write sequences.

SATA interface limits

The SATA 6.0Gb/s interface sets the maximum data transfer boundary for this drive. Mechanical latency and platter density govern real-world throughput within that ceiling. Firmware updates are managed directly through the host operating system to maintain compatibility.

Questions about this item

How much heat and power does the 7200 RPM HAT3310-16T produce when running continuously in a NAS?

The 16 TB drive is rated for an 180 TB yearly workload and 1.2 million hours MTBF, reflecting design for always-on operation in multi-bay enclosures.

What host interface and bay size does the 3.5" HAT3310-16T require to operate?

It connects via a SATA 6.0 Gb/s port and fits a standard 3.5-inch drive bay measuring 147 mm long, 101.85 mm wide and 26.11 mm high.

Will the CMR-based HAT3310-16T work reliably alongside older SATA drives in the same RAID array?

Conventional magnetic recording delivers consistent performance without the latency spikes of shingled drives, making it suitable for mixed-drive RAID sets.
