Seagate SV35.2 750GB surveillance drive

The Seagate SV35.2 ST3750640SV is a 750GB 3.5-inch internal hard drive built for digital video surveillance systems. It spins at 7200 RPM with a 16MB cache and connects through a SATA 3.0Gb/s interface. Firmware features let multiple video streams write at once while ATA7 streaming commands give finer control over read and write profiles.

Ideal for always-on recording arrays

This drive suits installers who need continuous recording on DVRs or NVR appliances where several cameras write simultaneously. The spin-down and PowerOn functions help manage heat and power draw in multi-bay enclosures. Builders who want a primary operating-system drive or fast random-access performance for general computing should look at something else.

SATA 3.0Gb/s interface decides compatibility

The drive uses the SATA 3.0Gb/s interface, so the host controller or backplane must support that exact link speed. A system limited to an older SATA revision will still work but at the lower rate, while a newer SATA 6Gb/s port will negotiate down automatically.
