Western Digital (WD) is one of the best-known hard drive makers, with product lines for desktops, laptops and surveillance. This collection lists the WD Purple surveillance hard drives in capacities from 1TB to 12TB, a 500GB 2.5-inch laptop hard disk and a WD Elements USB 3.0 casing to turn a 2.5-inch drive into portable storage.
WD Purple for CCTV recorders
WD Purple drives are designed for 24/7 video recording in DVRs and NVRs, unlike ordinary desktop drives built for lighter, intermittent use. The listings quote a 180TB per year workload rating on the larger models, and support for up to 64 HD cameras on the 1TB model.
How to choose capacity
- Cameras and resolution: more cameras and higher resolution use more space per day.
- Recording mode: continuous recording needs far more storage than motion-only recording.
- Retention: decide how many days of footage you must keep.
- Recorder limits: check the maximum drive size and number of bays in your DVR or NVR.

Laptop drive and external casing
For a laptop upgrade or replacement, the WD 500GB internal laptop hard disk is a 2.5-inch drive. A used or spare 2.5-inch SATA drive or SSD can be reused as a portable drive with the WD Elements USB 3.0 hard disk casing.

WD Green was discontinued in 2015 and folded into Blue. This collection stocks the Purple line plus a general-purpose laptop drive, so match the drive to the job rather than using a surveillance drive as a desktop disk. WD's own site offers a surveillance storage estimator and a compatibility selector for choosing a Purple drive.
Frequently asked questions
Can I use WD Purple in a desktop PC? It is a SATA III 3.5-inch drive, so it fits a desktop, but it is optimised for recording rather than general use.
What is the difference between 5400 and 7200 rpm? Higher rpm can help throughput; the surveillance models here balance performance with heat and noise.
Does the casing include a drive? No, the listing describes an empty enclosure.
