Purpose-built DVR storage

The Seagate Pipeline HD ST3500312CS is a 500GB 3.5-inch internal hard drive designed for continuous video recording. It spins at 5900 RPM with an 8MB cache and connects via SATA 3.0Gb/s. The drive supports up to 16 simultaneous HD streams and is rated for 24×7 operation in always-on DVR devices.

Ideal for surveillance and media recording

This drive suits installers building or upgrading consumer DVR systems that need reliable, constant write performance. It is not intended for users who need faster random access for operating systems or gaming workloads. Buyers looking for higher capacities or modern SATA 6Gb/s speeds should consider other models.

Check SATA power and data connections

Verify that your DVR or PC has a free SATA data port and a matching SATA power connector for a 3.5-inch drive. Confirm the chassis has a suitable 3.5-inch mounting bay with adequate airflow for continuous operation. Ensure the host system supports SATA 3.0Gb/s or backward-compatible speeds.

Questions about this item

Does this Pipeline HD drive need a SATA 3.0Gb/s port and 3.5" bay to work?

Yes, it connects via a SATA 3.0Gb/s interface and fits a standard 3.5" internal drive bay, so both must be available on the host system.

Will this 5900 RPM drive share a SATA controller with an existing SATA 3.0Gb/s drive without speed loss?

Each drive negotiates its own link speed on the controller, so the 5900 RPM unit will operate at SATA 3.0Gb/s alongside another SATA 3.0Gb/s drive.

How can I verify the drive is delivering 16 simultaneous HD streams after installation?

Monitor the DVR application for smooth recording and playback of up to 16 HD streams; sustained 24×7 operation without dropped frames confirms the Pipeline HD drive is performing as designed.
