Review: Works great!!! - Works great!!!
Review: Time is Precious especially when your protecting your property - 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.

## Questions & Answers

**Q: can it replace older hhd in nightowl dvr**
A: Yes. This hard drive is compatible with all recording units.

**Q: What is the difference between 3tb purple wd30purz and wd30purz, very confusing?**
A: Absolutely nothing. They are the same.

**Q: Is this compatible with annke surveillance camera system 8ch 1080p lite h.264+ dvr with (8) hd 1080p outdoor weatherproof cameras cctv security camera**
A: As the owner of South Jersey Surveillance Systems, I can assure you that any WD purple or Seagate Skyhawk hard drive is the appropriate type of storage drive for any and all DVRs and NVRs.

**Q: Whats the difference between this and the red plus?**
A: WD Blue HDDs are mainly used for general purpose storage, they are great all-rounders, and an average user can’t go wrong with Blue.

WD Green is basically same as Blue, but it lacks a bit of performance. However, it is the most eco-friendly HDD, and it’s quite cheap.

WD Blacks are for pure performance including gaming, media, and content creation. Also one of the most expensive HDDs.

WD Red is a NAS drive. It’s optimized for NAS systems.

WD Purple is for surveillance. Advised for 24/7 operation.

WD Gold, probably the most premium of all. Made for a multitude of Datacenter-specific applications.

### ⭐⭐⭐⭐⭐ Easy install
*by S***9 on August 1, 2025*

When my 1TB Sata drive in my Cobra 8 channel surveillance recorder went out I decided to give this 2TB drive a try and so far it seems to have been a great choice. I unplugged the power and Sata cord and while holding upside down removed four screws holding HD to frame. I reversed the process and fired it up and got a message to format drive which took less than a minute and my cameras came back up. I was shocked I never had to redo my settings or create new password, the recorder was set just as before. Now we hope for longevity.
