8TB Hard Drives for CCTV & Home Storage
5 products in our Storage range — trade-grade UK stock from CCTV Master.
8TB hard drives sit in the sweet spot for CCTV storage: large enough for weeks of multi-camera footage, but still affordable per terabyte compared with 10TB+ drives. This range covers five 8TB 3.5" SATA drives, including surveillance-oriented and enterprise-class options from Seagate, Toshiba, Western Digital and Lenovo.
What 8TB actually buys you
Recording time depends on camera count, resolution and how much motion is in the scene, so there's no single figure that fits every setup — as a rule, more cameras or higher resolution means footage gets overwritten sooner.
How to choose
- Duty cycle: drives built for 24/7 continuous recording (as this range is intended for) are designed to run constantly, unlike typical desktop drives.
- Spin speed: the Seagate BarraCuda here runs at 5400RPM; the Toshiba MG and Lenovo enterprise drives run at 7200RPM, which generally suits busier multi-camera systems.
- Class: enterprise drives (Toshiba MG, Western Digital Ultrastar, Lenovo 00XH265) are built for heavier, always-on workloads than compute-focused drives.
- Interface: all five use 3.5" SATA, so check your DVR/NVR has a free 3.5" SATA bay before buying.
Match the drive to your recorder's supported capacity and interface, and to how continuously your system records.
8TB — frequently asked questions
How many days of footage will an 8TB drive store?
It depends on your number of cameras, resolution and how much motion triggers recording, so recording time varies a lot between systems.
Do I need a special hard drive for CCTV, or will any 8TB drive do?
Drives built for continuous 24/7 recording, like the surveillance and enterprise models in this range, are designed for constant operation rather than occasional desktop use.
What's the difference between the 5400RPM and 7200RPM drives here?
The Seagate BarraCuda runs at 5400RPM, while the Toshiba MG and Lenovo enterprise drives run at 7200RPM, which generally handles busier multi-camera recording better.
