4TB storage drives for CCTV recorders
This range covers 4TB drives suitable for use in CCTV DVRs, NVRs and PCs, alongside a portable USB option for backup and footage export.
For recording duty, the choice usually comes down to workload rating and rotational speed rather than raw capacity, since all six drives here hold 4TB.
How to choose
- Surveillance-rated drives — the Seagate SkyHawk 4TB (5900RPM) and Toshiba S300 4TB (5400RPM) are purpose-built for continuous multi-channel recording workloads.
- General SATA 3.5" drives — the listed Seagate and unbranded 4TB SATA options are positioned for 24/7 continuous recording use in CCTV kits.
- Enterprise HDD — the Lenovo 4TB 7.2K SATA drive (00XH226 / 02YH047) is a higher-spec enterprise unit, useful where server or NAS-grade duty cycles are expected.
- Portable backup — the Verbatim 4TB Store 'n' Go USB 3.0 drive is for offloading and archiving footage rather than continuous recording.
Match rotational speed and workload rating to channel count and recording schedule; surveillance-class drives are generally built for sustained write cycles that desktop drives are not.

4TB — frequently asked questions
What's the difference between a surveillance-rated 4TB drive and a standard 3.5" SATA drive?
Surveillance-rated drives like the Seagate SkyHawk and Toshiba S300 are designed for continuous multi-channel recording workloads, while general SATA drives are typically built for lighter, intermittent use.
Can I use the Verbatim 4TB portable drive as my main CCTV recording disk?
It's a USB 3.0 portable drive intended for backup and transferring footage, not for installation inside a DVR/NVR as the primary recording disk.
Is the Lenovo 4TB enterprise HDD suitable for CCTV recording?
The Lenovo 4TB 7.2K SATA drive is an enterprise-grade unit, so it can generally handle sustained write workloads, though it isn't marketed specifically as a surveillance drive.
