Western Digital WD240PURP 24TB 7200RPM SATA internal hard drive

Purpose-built surveillance storage

The WD Purple Pro WD240PURP is a 24 TB 3.5-inch internal hard drive engineered for always-on surveillance workloads. It uses conventional magnetic recording and a SATA 6.0 Gb/s interface to sustain high write throughput across multiple camera streams. The 7200 RPM spindle speed supports rapid data access for recording and playback. It is designed for servers, storage systems and camera devices that demand continuous operation.

Upgrade from lower-capacity or archive drives

This drive replaces smaller surveillance drives when retention periods expand or camera counts increase. The jump is worth it when a single volume must hold weeks of high-resolution footage without spanning multiple disks. It also supersedes archive-class drives that cannot sustain the constant write cycles of 24/7 recording. The CMR technology avoids the performance dips associated with shingled recording under heavy sustained loads.

Fits standard 3.5-inch drive bays

Installation requires a 3.5-inch bay, a SATA data cable and a SATA power connection from the host system. The drive frees up controller ports and physical slots by consolidating up to 24 TB into one unit. It works with any backplane or HBA that supports SATA 6.0 Gb/s, letting builders scale storage without adding controllers. No special cooling beyond standard chassis airflow is specified.
