4TB storage range for CCTV and general backup use, comprising five drives: one Verbatim portable USB 3.0 external hard drive, and four internal 3.5" SATA drives (a Lenovo enterprise HDD, two Seagate options including SkyHawk, and a Toshiba S300 surveillance drive).
The 3.5" SATA drives suit recorders and workstations needing continuous internal storage, while the Verbatim portable drive suits ad-hoc backup, footage export, or transferring recordings between sites without opening a case.
How to choose
- Recording workload: Seagate SkyHawk and Toshiba S300 are purpose-built surveillance drives, designed for the sustained write cycles of DVR/NVR recording rather than intermittent desktop use.
- Server-grade needs: the Lenovo 7.2K enterprise HDD suits servers or NVRs where enterprise-class components are specified.
- Rotational speed: SkyHawk runs at 5900RPM, S300 at 5400RPM — a factor where drive throughput needs weighing against operating noise and heat.
- Portability: the Verbatim Store 'n' Go is the only drive here designed for external, tool-free use rather than fitting inside a recorder chassis.
- Interface: all internal drives use SATA 3.5", so confirm bay size and connector compatibility with the target recorder or server before ordering.
Match the drive type to the deployment: surveillance-rated drives for always-on recording, enterprise drives for server duty, and the portable unit for offline backup or footage handover.
