Western Digital18TB WD Purple Pro Surveillance Internal Hard Drive HDD - SATA 6 Gb/s, 512 MB Cache, 3.5" - WD181PURP

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.

Bought this after the drive in my NVR died.Installed this and it has performed flawlessly in the couple months I've had it. FWIW, this make and model is widely regarded as the best for security camera recording as far as the research I've done online.

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.

ERRORS, ERRORS, ERRORS! This drive is unacceptable, and I would not recommend. It's a MECHANICAL drive (not SSD), which means it has a floating head that reads data on a platter (like a record player). Thus it needs to be PADDED and protected. Nope.... got it in a plastic bag after probably being tossed around in a mailtruck, which damaged the drive or crashed the drive heads. Unbelievable that there is no common sense or policy when it comes to these drives. And I notice mine is not the only review to report this. So why hasn't anything been done yet about it? I got the same drive 6 years ago and it certainly wasn't like this. It was perfect and is still going strong. But I guess times have changed. I would not recommend buying these at all... they just don't care anymore.

I was not able to playback on my home surcurity cameras. I purchased the disk, it has more storage, little to no noise and has been working properly.

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.

Delivered as advertised, no problems to date.

Excelente, me función perfecto para mi DVR.
