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

A 500GB 3.5" SATA hard drive from Seagate's Barracuda range, supplied ready to slot into a DVR or NVR for continuous recording duty. It suits jobs where footage retention matters more than raw capacity — small retail premises, offices, or a single-site residential install running one or two channels.

Key specs

• Capacity: 500GB
• Rotation speed: 7200 RPM
• Interface: SATA III
• Cache: 128MB
• Form factor: 3.5 inch
• Compliance: RoHS compliant
• Category: Internal Hard Disk Drive (Drives, Storage & Blank Media)

The 7200 RPM spindle speed keeps read/write access fast enough for continuous write cycles, which is what 24/7 recording demands rather than a desktop drive doing occasional file transfers. SATA III gives high-speed data transfer to the host recorder.

Beyond CCTV recorders, this drive fits desktops, servers, NAS devices, and external enclosures, so it's a reasonable stock item for installers who also handle general IT alongside surveillance work. Confirm the DVR/NVR's supported drive capacity before specifying, particularly on older recorder models with capacity ceilings.

For loop recording setups, remember the drive itself only stores data — the recorder's overwrite/loop recording setting controls whether old footage gets cleared automatically once the drive fills.
