4TB Hard Drives: CCTV Surveillance & Home Storage
6 products in our Storage range — trade-grade UK stock from CCTV Master.
4TB storage drives sized for DVRs, NVRs, servers and everyday backup, giving buyers a straight choice between general-purpose drives and ones built for constant CCTV recording.
This range covers general portable storage (the Verbatim USB 3.0 external drive), an enterprise SATA drive (Lenovo 7.2K), and drives specifically built for surveillance workloads (Seagate SkyHawk, Toshiba S300, plus two listed Seagate 4TB SATA drives for CCTV use).
How to choose
- Where it's going — a portable USB drive (Verbatim) suits backing up footage to a laptop or PC; an internal 3.5" SATA drive is what your DVR/NVR bay actually takes.
- Recording workload — surveillance-class drives (SkyHawk, S300) are built for the sustained, 24/7 write cycles of continuous CCTV recording, unlike drives designed for occasional file storage.
- Rotational speed — SkyHawk runs at 5900RPM, the S300 at 5400RPM; the Lenovo enterprise drive runs at 7.2K (7200RPM), reflecting its server/enterprise role rather than CCTV recording.
- Interface — all the internal drives here use SATA; the Verbatim connects via USB 3.0.
- Capacity fit — every drive in this range is 4TB, so the deciding factor is which drive type matches your recorder and recording pattern, not size.
Check your DVR/NVR's supported drive interface and maximum capacity before ordering.
4TB — frequently asked questions
What's the difference between a surveillance hard drive and a normal one?
Surveillance drives like the Seagate SkyHawk and Toshiba S300 in this range are built for the sustained, continuous writing that 24/7 CCTV recording involves, rather than occasional file access.
Can I use the Verbatim portable drive with my CCTV system?
It's a USB 3.0 external drive best suited to backing up footage from a PC or laptop, rather than sitting inside a DVR/NVR bay as the main recording drive.
