18TB storage drives for CCTV recording
Three 18TB 3.5" SATA hard drives for high-capacity NVR and DVR installations: the Toshiba MG Series Enterprise, the Toshiba N300 NAS drive, and the Western Digital WD180EMFZ.
At this capacity, retention headroom matters more than raw throughput — a single 18TB drive can hold weeks of multi-camera footage before overwrite, cutting the number of bays needed in a recorder.
How to choose
- Duty class — the Toshiba MG Series is built for enterprise/24-7 workloads, suiting always-recording multi-camera sites.
- NAS-rated vibration tolerance — the Toshiba N300 is designed for multi-bay NAS/NVR enclosures where several drives spin side by side.
- Spindle speed — the WD180EMFZ runs at 5400RPM, the two Toshiba drives at 7200RPM; higher RPM generally suits busier write loads, lower RPM favours quieter, cooler running.
- Bay count of the recorder — match drive count to available SATA bays and confirm the recorder's per-drive capacity limit supports 18TB before ordering.
All three are 3.5" SATA drives, so they fit standard NVR/DVR and desktop NAS bays without adapters.

How does the Toshiba MG Series compare with the N300 in the 18TB size?

Is the WD180EMFZ suitable for continuous recording?

Will an 18TB drive fit any NVR?
All three drives use the standard 3.5" SATA form factor, but you should confirm your NVR or DVR supports single-drive capacities of 18TB before purchase.
Do these drives come with mounting brackets or cables?
