Product Description
The WD120EDAZ (SKU HDD-12TB-Western-Digital-R) is a 12TB internal hard drive built for storage capacity, not high-performance write endurance — the thing to check before it goes into a recorder or NAS.
Key specs
- Capacity: 12TB
- Form factor: 3.5-inch internal
- Interface: SATA III, 6Gb/s
- Spindle speed: 5400 RPM class — this is what keeps power draw, noise and heat down inside an enclosed NVR or NAS chassis
- Sector technology: Advanced Format (AF) 4K, for storage efficiency and compatibility with current operating systems and recording platforms
- Labelling: OEM/internal-use
Where it fits
This drive suits light-to-moderate NVR or DVR recording loads, desktop and external-enclosure storage, general backup and archiving, and NAS builds without heavy throughput demands. It runs on standard SATA infrastructure and supports typical RAID configurations for redundancy.
What to check before buying
Confirm your recorder or NAS accepts a 5400 RPM-class, Advanced Format drive at this capacity — not every older DVR chassis does. Given it's positioned for controlled, moderate workloads rather than continuous high-intensity recording, it's worth matching channel count and recording settings to what the drive is actually rated for before committing a system to it. This is not a dedicated surveillance-grade drive, so treat it as suited to smaller installations and general storage rather than heavy continuous multi-camera recording.

Frequently Asked Questions
Is this drive suitable for a heavily used NVR recording multiple cameras continuously?
It's built for high storage density rather than high write endurance, so it's best suited to light-to-moderate recording loads, not continuous high-intensity multi-camera recording.
What interface does it use and will it fit standard systems?
It uses a SATA III 6Gb/s interface and integrates with standard SATA-based infrastructure, including typical RAID setups.
Does the 5400 RPM speed matter for CCTV storage?
Yes — the 5400 RPM class keeps power use, noise and heat lower, which suits enclosed NVR, DVR or NAS chassis running continuously.
Is this a dedicated surveillance-grade hard drive?
No, the manufacturer positions it as suited to controlled, moderate workloads rather than a purpose-built surveillance drive.
