18TB storage drives for CCTV recording
This range covers three 18TB 3.5" SATA hard drives suited to DVR/NVR storage upgrades and rebuilds: the Toshiba MG Series Enterprise drive, the Toshiba N300 NAS drive, and the Western Digital WD180EMFZ.
How to choose
- Duty cycle and workload class: the MG Series is built as an enterprise-class drive; the N300 is positioned for NAS and always-on multi-bay recording; the WD180EMFZ is a standard internal SATA HDD. Match the drive's intended workload class to how the recorder will run — continuous multi-camera writing places sustained demand on a disk.
- Spindle speed: both Toshiba drives run at 7200RPM; the WD180EMFZ runs at 5400RPM. Higher RPM generally supports faster sustained throughput, which can matter on higher-channel-count NVR setups, though actual performance also depends on the recorder and controller.
- Interface: all three use SATA, so they fit standard SATA bays in DVR/NVR chassis without adapters.
- Capacity: all three are 18TB, giving a consistent capacity baseline — the deciding factor is workload class and spindle speed rather than storage size.
Check your recorder's supported drive list before fitting any of these to confirm compatibility with your specific NVR/DVR model.
