Western Digital 4TB WD Purple Surveillance Internal Hard Drive HDD - SATA 6 Gb/s, 64 MB Cache, 3.5" - WD40PURZ

Best drive for security camera footage storage. I've had mine in constant use for 6 years and it's still going strong.

Great product! Great price!

Bought one of these for my surveillance DVR in July 2018 and it was still going strong when the DVR was replaced in November 2022. New DVR had Seagate Skyhawk that died shortly after 2 years so going back to WD Purple.

excellent product,

I bought this drive for the UDM pro surveillance system by Ubiquiti. It functions exactly as it should and supports the cameras as expected. One thing it does not mention though is that this drive is quite noisy. In our living room there is a constant noise coming from that drive. I have taken steps to cushion the tray which helped some, but did not alleviate the problem. After doing some research, it turns out that the large capacity drives (over 6 TB) are gas filled and more noisy than their smaller counterparts. As I understand it, this is a problem with most major drives for surveillance systems. I am happy with the drive we purchased, but if we had it to do over, we would have purchased a quieter drive.

Great Jellyfin starter drive. Awesome Nextcloud Android backup drive. Rock soild performance.

Being a Fan of Western Digital I decided to give their Surveillance Hard drive a try.. I currently have 9 cameras running constantly at my home to keep my property protected. And I had a 1tb drive on my system and had only 4 days of backup which these days is NOTHING.. I now have one day over 2 weeks or backup.. Totally going to upgrade to a 12 tb once I can get it. worth its weight in gold.. Just remember you're not going to be able to do a visual inventory of your stuff every day but with a good NVR and a large hard drive you will be able to periodically check your stuff and notice differences and catch what is going on. The larger the Hard Drive the better chance you have to keep a good eye on your stuff and have evidence in case of a situation. My situation is odd due to having a multitude of resolutions. Honestly All of my cameras (except 2) are from the Same Manufacture and I love them.. Probably shouldn't mention S3VC cameras but sorry gotta say excellent cameras for any good NVR (AMCREST) My cameras have resolutions from 1080 to 5 mp cameras(oldest camera is 720 ). Including a great camera from FOSCAM (which I didn't know it had audio) So you may have 4 or 6 cameras which most people get Standard resolution cameras (which are fine if your just wanting to see what happened without enough resolution to see who it was in most cases) I go 1080 or higher just so I can get good visuals of who or what happened with better ability to see what your protecting. So in a situation with 6 cameras at Standard Definition you will have at more than a month of recording easy. This drive is designed for Security camera recording and should last longer than a regular system drive. Will recommend to anyone who is in the market to buy a hard drive.

Buen producto A+++
