This bad boy is still trucking along in our security system since purchase. Does what it’s supposed to. Fairly quick remote viewing response, fairly low noise, zero downtime. Work horse.

On time and as described. Works well for expanding or replacing surveillance nvrs drive capacity.

I appreciated being able to purchase these through Amazon at a lower rate than I normally would as a authorized dealer for security cameras. This product in particular is the item of choice for most pros. There is some other items coming out on the market at a lower price, but they have not which did the test of time to this point. And when it comes to security, I don’t like to gamble. Thanks again for the prompt delivery as well.

We've been deploying western digital purple for years now for are NVR or DVR All the hard drives that we've purchased,Through the years we've only had a couple bad drives go out on us and Western Digital took care of us and replaced the drive.

I actually bought this for my home security camera NVR system, after I advised a friend to buy the exact same thing for their same system and I would install it, as the existing HDD was not large enough for continuous storage beyond several days. It works great, was easy to install, came packaged very well, and the price was very reasonable. The only complaint that I have is that the drive has a very audible "click" to it as it reads and writes, which normally would not be an issue for me or my friend, but we both have the NVR systems in our office, and when it is quiet it can be a little maddening to just hear the clicking of the hard drive. I'm starting to get used to it, otherwise, and do love the fact that it has much more storage capabilities for the application I am using it for. I have not seen any signs of failure, or degradation, and knowing that my HDD as well as the same one for my friend are the same item and have the same noise "issue", it puts my mind at ease thinking it is likely supposed to be that way. This could also just be a common item with surveillance system HDDs, I haven't had anything other than an SSD in quite some time, so maybe I am spoiled!

Item as described. Installed to upgrade Honeywell NVR storage capacity. Installed easy, works as described.

Infelizmente tive que devolver, pois comprei errado!

Prodotto arrivato nei tempi previsti. Questo è HDD che uso per le videosorveglianze dei miei clienti. Di questa serie uso varie capienze e ne sono sempre soddisfatto. Alcuni esemplari stanno funzionando da 10 anni.

As expected from Western Digital, it simply worked efficiently and quietly with very little noise/vibration/heat. My application is what the drive is designed for - CCTV and it worked immediately with no fuss from switch on.

Le disque dur est défectueux. "Erreur d'entrée/sortie" lorsque j'essaie d'initialiser le disque, il est inutilisable. Le disque était vendu comme étant un produit neuf, hors j'ai reçu un disque avec label "recertified". C'est un disque d'occasion qui provient d'un retour client chez Western Digital et qui a été re-embalé et remis en vente. Belle arnaque.

Not working , dead HDD!
