  • InterfaceSATA 6.0Gb/s
  • Capacity16TB
  • RPM7200 RPM
  • Form Factor3.5"
  • 16 TB capacity stores massive surveillance archives
  • 7200 RPM spindle delivers sustained write throughput

  • 5-inch form factor fits standard NAS bays
  • SATA 6.0 Gb/s interface connects to existing controllers

Built for 24/7 surveillance workloads

This 16TB hard drive is engineered for continuous video recording in network video recorders. It handles the elevated heat and vibration found in always-on surveillance environments where standard desktop drives are not designed to operate.

SATA 6.0Gb/s interface practical limits

The SATA 6.0Gb/s connection caps sequential throughput at the interface maximum. Mechanical latency at 7200 RPM and the 512MB cache size determine real-world sustained transfer rates during heavy multi-stream write activity.

16TB capacity with 512MB cache headroom

Sixteen terabytes store weeks of high-definition footage from multiple cameras. The large cache absorbs burst write traffic, but sustained 24/7 recording will eventually fill the volume and require archiving or overwrite cycles.

Perguntas sobre este artigo

Should I pick the 16TB Red Pro or a smaller capacity for my NAS?

The 16TB model delivers the highest raw capacity in the Red Pro line, reducing the number of drives needed to reach a given storage target.

What does the 7200 RPM rating mean for daily NAS workloads?

The 7200 RPM spindle provides higher sustained throughput than slower-spinning drives, helping maintain performance during heavy multi-stream write workloads.

Will the SATA 6.0Gb/s interface limit the 16TB drive in a modern NAS?

The SATA 6.0Gb/s link caps the burst transfer rate at 6 Gb/s; sustained rates are lower and depend on the drive’s internal media speed.
