Western Digital Green Power - 1TB - HDD 3.5" SATA Hard Drives - Ideal for 24/7 continuous recording

The Western Digital Green 1TB HDD 3.5" SATA Drive (WD10EURX) is a 1TB internal hard drive built for recorders that run around the clock rather than desktop bursts of activity.

Note there's a spec contradiction worth flagging honestly: the drive is described both as a 5400 RPM "Green" model prized for quiet, low-power running, and elsewhere as 7200 RPM. Check which spindle speed applies to the exact drive before fitting it if RPM matters to your setup — either way, it's built to stay on continuously rather than for occasional use.

Where it fits

• Capacity: 1TB, aimed at 24/7 continuous recording and general data storage rather than short-term use.
• Interface: SATA III, for high-speed transfer between the drive and your recorder or PC.
• Compatibility: works with DVR and NVR surveillance systems, and equally at home in desktops, servers, NAS devices, and external enclosures.
• Form factor: standard 3.5-inch, fitting the drive bay of any CCTV kit or package sold with this option.

Installation

The drive arrives fully installed and ready to go before dispatch when bought with a CCTV kit or package, so there's no separate fitting step for the recorder side once it's connected.

If you're adding this to an existing recorder rather than a new kit, check your DVR or NVR's maximum supported drive capacity first — pairing storage size with what the recorder can actually address avoids wasted space.
