Surveillance-Grade 500 GB Drive

The Seagate SV35.3 ST3500320SV is a 500 GB 3.5-inch internal hard drive built for continuous video recording. It spins at 7200 RPM with a 32 MB cache and connects over a SATA 3.0 Gb/s interface. The drive is supplied as a bare unit and carries a design target of more than one million hours MTBF with an annualised failure rate below one percent.

Always-On Recording Workloads

This drive suits installers and system integrators deploying DVRs, NVRs or JBOD arrays that must write multiple streams around the clock. It is not intended for desktop boot duties, gaming libraries or workloads that demand the low latency of solid-state storage. Buyers who need higher capacities or faster random access should evaluate other storage classes.

SATA 3.0 Gb/s Interface

The single specification that decides fit is the SATA 3.0 Gb/s host connection. Any recorder or server backplane limited to this generation will accept the drive directly, while controllers that only support newer SATA speeds will still operate at the 3.0 Gb/s rate.

Perguntas sobre este artigo

Which SV35.3 version should I pick for a 500 GB surveillance array?

This model is the 500 GB variant of the SV35.3 series, offering 7200 RPM and 32 MB cache in a 3.5 inch form factor.

What does the 7200 RPM rating deliver in a live DVR?

The spindle speed supports sustained write throughput for multiple simultaneous video streams with low average latency of 4.16 ms.

How does the SATA 3.0 Gb/s interface limit real-world transfer?

The SATA 3.0 Gb/s link caps burst throughput at 3.0 Gb/s, so sustained rates will stay within that ceiling during recording.
