Well made
I installed this in my security camera NVR to replace the existing 2 terabyte disc. The software formatted it quickly and it immediately began recording. I’ve done a couple of playbacks with no issues. It’s now completely full and the overwrite process has not experienced any issues.

Perfect for an NVR.
Great drive for little money. I use these only for video recording and the purple drives work great for that. They are stable and performant. The longevity is good as well.

Works for Reolink NVR
I have this 8TB hard drive in my Reolink RLN8-410 NVR. The actual storage is 7.4 TB when you put it in, which is par for the course. It stores about 15 days of 24/7 on 7 cameras.

Was good until now… less than a month with the drive half written on
WD has been in the drive business for ages. Drive is quiet, installs easily and works well in my NVREdit: so after being installed for less than a month, drive starting to make some noise. An intermittent squeaking almost like a faint beep. To me sounds like something’s going on in the head as though it hit bad sectors on the drive platters. I turned off the recording feature on the NVR and the noise went away so now I know it’s not the machine itself….. bad sectors in less than a month and the drive was barely half written on…. I reformatted the drive and now it’s quiet again at the cost of losing all my data. Am I going to have to do this every month? ….. I chose this drive because of WD reputation in the HDD business, now that thought went down the drain…..Edit: after formatting the drive, noise went away for a few days, started to do the same thing again…. Returning this and ordering from different major manufacturer

WD Purple HD for NVR Security Camera Recording
Excellent for NVR use!I record multiple security cameras 24/7, some through WiFi and others through CAT6 for high resolution.Has no speed problems keeping up with recording multiple cams at same time.Storage capacity gives a minimum of 60-days record time for all cams... I run at max video resolution, so I could probably bump that up to 120+ days if needed by reducing video resolution a little.Previously I used just a standard HD in my NVR which was a bit noisy, always ran very hot and eventually failed after 3 years.Been using this WD Purple drive for a few months now.... completely silent and stays at room temperature!Absolutely pleased!

Noisy but reliable.
Performs well but it is noiser than smaller capacity drives. Seems like all the bigger drives are like that. It's the loudest part of my NVR now.

Good sized drive for a surveillance camera system at a good price
New 4 TB camera surveillance system purple drive. Low noise with fine read/write time and a direct plugin into a Lorex system.
