Product Description
The WD140EDFZ is a 14TB 3.5-inch SATA hard drive built for high-capacity storage in desktop systems, external enclosures and entry-level surveillance setups. It suits jobs where storage volume matters more than write endurance — bulk backup, archive storage, and small to medium CCTV installs with a limited number of camera streams.
Key specs
- Capacity: 14TB
- Form factor: 3.5-inch internal
- Interface: SATA III, 6Gb/s
- Spindle speed: 5400 RPM class
- Sector format: Advanced Format (AF) 4K
- Rated use: internal desktop and storage systems; light to moderate NVR/DVR duty
Running at 5400 RPM class speed keeps power draw and heat lower than faster spindle drives, which helps in enclosed NVR or NAS housings running continuously. The AF 4K sector design keeps it compatible with current operating systems.
For CCTV projects, this drive fits small to medium camera counts where the recorder workload stays light to moderate — think office or residential block installs rather than large multi-stream sites. It pairs with standard SATA-based NVR or NAS hardware and supports basic RAID redundancy setups. It is supplied as an OEM internal-use drive and is not positioned as a surveillance-grade or enterprise unit, so it's best specified for controlled workload environments rather than continuous high-write recording at scale.

Frequently Asked Questions
Is this drive suitable for a full multi-camera NVR setup?
It's rated for light to moderate NVR/DVR usage, so it suits small to medium camera counts rather than large continuous multi-stream deployments.
What interface does the WD140EDFZ use?
It uses a SATA III 6Gb/s interface, compatible with standard SATA-based NVR, NAS and desktop hardware.
Can this drive be set up in a RAID configuration?
Yes, it supports basic RAID configurations for redundancy alongside other SATA drives.
Is this a surveillance-grade drive?
No — it's an OEM internal-use drive, not a dedicated surveillance-grade or enterprise model, so it's best suited to controlled workload environments.
