Seagate 500GB - 3.5" SATA Hard Drives - Ideal for 24/7 continuous recording

Seagate Barracuda ST500DM002 — 500GB 3.5" SATA

A 500GB desktop-class drive spun at 7200 RPM with a SATA III interface and 128MB cache, built to the standard 3.5-inch form factor used across DVR and NVR bays.

Key specs:

• Capacity: 500GB
• Rotation speed: 7200 RPM
• Interface: SATA III
• Cache: 128MB
• Form factor: 3.5"
• RoHS compliant

Fit and application

Drops into any DVR or NVR chassis taking a standard 3.5" SATA drive, and works equally well in desktops, servers, NAS units and external enclosures. The 7200 RPM spec keeps write throughput steady under the sustained load of continuous multi-channel recording, which is the workload that kills consumer-grade drives sold for occasional use.

Configuration note for installers

Drives shipped for CCTV use arrive fitted and ready to record, but the recorder's own storage settings still determine behaviour once the disk fills. If a connected recorder reports "Storage Full", check the Storage/HDD menu and enable Overwrite (loop recording) so the oldest footage is purged automatically instead of halting capture. This is a recorder-side setting, not a drive fault, and applies regardless of which NVR/DVR brand the drive is paired with.

Suitable for 24/7 continuous recording workloads where reliability under sustained write cycles matters more than peak burst speed.
