Western Digital Ultrastar 8TB Enterprise SATA 3.5" Hard Drive

8TB SATA drive built for continuous, multi-drive storage duty — not a desktop drive repurposed for a server rack. Here's what that means in practice for a CCTV or IT install.

Key specs

• Capacity: 8TB — enough for extended surveillance recording, backup sets, or virtualisation storage on a single drive.
• Series: Western Digital Ultrastar — WD's enterprise line.
• Form factor: 3.5-inch — fits standard enterprise drive bays in rack-mounted and tower servers.
• Interface: SATA — matches enterprise server backplanes and storage controllers.
• Duty rating: built for 24/7 continuous operation, not occasional use.
• Array use: suitable for RAID configurations and high-density multi-drive arrays.

Where it fits

This drive suits recorders and servers where the workload never stops: surveillance recording servers, backup infrastructure, cloud storage nodes and NAS units built for enterprise duty. Because it's rated for continuous operation, it's a sounder choice than a standard desktop drive for a recorder that runs around the clock.

If you're deploying it in a RAID array, check your controller and backplane support SATA drives of this capacity before ordering multiples — the SATA interface itself is common ground, but array configuration and drive-count limits are set by the recorder or server, not by this drive.
