Surveillance optimisation

This 3 TB desktop drive is built for 24x7 video surveillance workloads. The SV35.6 Series design targets continuous write streams typical of multi-camera recording systems. It suits installers and system builders who need reliable local storage for security footage. It is not for buyers who need faster random access for operating systems or databases.

SATA 6.0Gb/s throughput ceiling

The SATA 6.0Gb/s interface caps sustained transfer rates well below the drive’s own 7200 RPM potential. Real-world sequential speeds will hit the bus limit before the platters saturate. Users planning RAID arrays or high-channel-count NVRs should verify controller bandwidth per port. This drive cannot exceed the SATA link speed regardless of cache or spindle performance.

Standard 3.5 inch SATA installation

Mounting uses ordinary 3.5 inch drive bays with standard SATA data and power cables. No special drivers are required for the SATA interface. The bare-drive packaging omits screws and cables, so installers must supply their own. A common error is forgetting to enable AHCI mode in BIOS, which can limit hot-plug support and queue depth.

Questions about this item

Should I choose the 3TB capacity or a different size from the SV35.6 Series?

The SV35.6 Series uses 1TB-per-disk technology to deliver cost-effective 1TB, 2TB and 3TB capacities. Pick the capacity that matches the total video storage you need for your surveillance system.

What does the 7200 RPM speed mean for a surveillance recorder running 24x7?

The 7200 RPM spindle provides the sustained throughput required for continuous multi-stream video recording in 24x7 surveillance environments.

Will the SATA 6.0Gb/s interface limit performance in my NVR?

The SATA 6.0Gb/s interface supports the full transfer rate of the drive; real-world throughput is governed by the 7200 RPM mechanics and 64MB cache.
