Twenty silver 3.5 inch SATA hard drives in a pack

Western Digital

Western Digital WD Purple WD10PURZ 1 TB 3.5" 5400 rpm SATA 20-pack

SKU CH-CNBX-TDFC3

A 20-pack of 1 TB 3.5-inch SATA drives at 5400 rpm for network video recorder storage

  • 1 TB capacity for up to 20 surveillance cameras
  • 5400 rpm spindle speed optimised for continuous video recording
  • SATA 600 interface compatible with standard NVR systems
  • 5 inch form factor fits desktop drive bays
  • 20-pack bundle simplifies multi-bay deployments

Surveillance storage bundle

This pack contains twenty 1 TB 3.5-inch drives built for continuous recording in network video recorders. Each unit spins at 5400 rpm and connects over a SATA 600 interface. The set is suited for installers who need multiple bays filled in a single order.

Fit for multi-bay NVR builds

The drives serve projects that write many video streams at once and that can accept a 5400 rpm spindle speed. They are not intended for boot drives, high-transaction databases or workloads that demand faster random access. Buyers who need lower power draw per terabyte or a smaller form factor should look elsewhere.

SATA 600 interface

The single specification that determines compatibility is the SATA 600 connection. The host must provide a standard SATA data port and matching power connector for each drive. Without that interface the drives cannot be installed.

Questions about this item

Does the 3.5 inch form factor fit a standard desktop drive bay?

Yes, the 3.5 inch size matches standard desktop internal bays and uses the SATA interface for both data and power connections.

What is the correct way to install the drives in a multi-bay NVR and what step is often missed?

Mount each drive securely in the bay, connect the SATA data and power cables, then ensure the NVR recognises all drives and formats them before recording.

How long is the manufacturer warranty on these drives and what does it cover?

The drives carry a 3 year warranty from the manufacturer covering defects in materials and workmanship under normal surveillance workloads.
