Great disk for CCTV NVR
Excellent Hard Drive that I have added in to a NVR. Disk was detected straight away and formatted perfectly. This operates perfectly fine for multiple 4k feeds so speed wise does the job. I've only had it installed for a matter of weeks so cannot determine how resilient it is.

A very good and reliable hard drive for CCTV.
I bought this to replace an identical one that I bought about 10 years ago. I use them for multi camera CCTV that records AHD 24/7. 8TB stores 8 channels for around 4 weeks before overwriting the files. Comes very well packed and is a simple 'plug, format and play'. Delivery was quicker than expected. All good.

Working fine, just a little noisy
Arrived on time, and I've installed it into my UDMSE without any issues. However, it's noisier than I expected. Apparently, this is typical with larger disk drives

I had problems with it, it didn't work at all - but the package was damaged by post. the disk was making a mechanical click and it was not recognized by the Operating System. I opened a case to the manufacturer in Czech Republic and they replaced it very fast. I had also the seller willing to replace it - even if the retun window of 30 days has passed. The replacemt disk works very well. high continous transfer rate, no excessive noise. Asking Western Digital to replace it with a RED Pro one, I received ensurance that this model (Purple Pro) is build with the same high standards as the Red serie. Do not buy this product if you want to create a RAID! For RAID, choose RED series.

There is no substitute for the quality and reliability of Western Digital's high-end products. Their black, gold, purple, and red lines of drives are excellent.

We are utilizing this on surveillance system and the images from the cameras are so much sharper than they were before. It was easy to set up. Our IT guy just plugged and set it up quickly. WD is a very trusted name in electronics.
