Common questions
How far can the Western Digital 8TB WD Purple Surveillance Internal Hard Drive, 256 MB Cache identify someone?
Western Digital does not publish both a sensor resolution and a focal length for this product, and DORI distance cannot be derived without both. Rather than estimate one, this sheet leaves it out. If you have the manufacturer datasheet to hand, the DORI calculator on this site works the distance out from those two figures directly.
What is the infrared range of the Western Digital 8TB WD Purple Surveillance Internal Hard Drive, 256 MB Cache?
Western Digital does not publish an infrared range for this product, so this site does not state one. An invented figure would be worse than no figure, because a reader would plan a camera position around it. Where a maker does publish a range, treat it as the distance its own lamp reaches in ideal conditions rather than the distance at which a face stays identifiable.
What specifications does Western Digital publish for this product?
Capacity: 8 TB. Everything in the table on this page is taken from the manufacturer listing rather than measured by us. Any row shown as not published is a figure this maker does not state, and this site will not fill that gap with an estimate.
Is the Western Digital 8TB WD Purple Surveillance Internal Hard Drive, 256 MB Cache worth buying?
Eight terabytes of surveillance rated storage, the usual pairing with a sixteen channel recorder. This site does not test products in person, so that assessment comes from the published specifications, the applicable standards and verified owner reports rather than from hands-on trials we did not run. Prices change often, so check the current listing before deciding.

Work out whether it fits
Specifications are published figures, not measurements we took. This site does not test products in person. Where a maker does not publish a figure, such as a true infrared range or a low light rating, this page says it is not published rather than estimating one, because a reader planning a camera position around an invented number is the worst outcome this site could produce.
