Installation was easy. All I did was plug it in

I bought this to use with my ZOSI 4CH 1080P HD WiFi NVR with (4) 1.0MP 720P HD. Installation was easy. All I did was plug it in. It works, and I didn't have to do anything else.

Purple drive recommended for video surveilance recording.

Running strong and was easy to connect and set up. This PURPLE model is most recommended for security cameras due to the constant recording of video. Another unit might be a little cheaper, but will not hold up to the constant recording. Pay the extra few bucks and get the unit made for recording video surveillance. It's worth it.

Works great for my Q-SEE QC888 NVR

Got it the next day. It worked right out of it's brown generic box. Used this one for my new QC888 NVR with no HDD. The MFR date was 5/2018. Fairly quiet with no clicking noise. This is the new generation. It does not heat up crazy - as expected. But, I do have a small fan running 24/7 inside the case. This did not come with mounting screws. You may want to salvage 4 pcs from an old computer.

Does work with Dahua NVR5232-16P-4KS2

First purple drive works great with my NVR5232-16P-4KS2 BEEN VERY HAPPY SO FAR .started using it first week of Jan 2018 so its been about 3 months no complaint first time i ever heard of purple HDD. I did a lot of research and many phone calls before I ordered. I wanted the best. This is it.. ATTENTION , 2ND DRIVE ARRIVED DEFECTIVE. HAD TO WRITE HERE BECAUSE IT WON'T LET ME WRITE ANOTHER REVIEW ON BUYING A SECOND ONE. THOUGHT IT WAS MY NVR BUT WASN'T. AFTER CALLING WESTER DIGITAL AND AMAZON. AMAZON REPLACED RAPIDLY NO HASSLE. SECOND ONE WORK AS SHOULD.. I WAS A LITTLE STRESS AND WD GAVE ME A DISOUNT FOR FURTHER PURCHASE. VERY RARE A DRIVE FAILS OUT OF BOX NOT SURE IF SUB ZERO COLD IN SHIPPING CAUSED A ISSUE .IM HAPPY I GOT A NEW ONE AND ALLS GREAT NOW

So far so good

For a few years now I've used HGST NAS drives for Camera DVR/NVR's....Noticing a while back that HGST released their newer model of that drive...increasing the cache to 128mb...I thought it could only get better. The reviews tell another story so I decided to go elsewhere. I ran into someone recently who mentioned they use these Purple drives and had for 2 years. I decided why not. I got my first one recently and put it into someone's camera NVR and it seems to work fine. Oh so quiet and quite snappy. Time will tell on the distance they go but so far, these have taken over the green drives successfully. It's funny how some companies Hard Drive models work great...and some are dud's. Go figure how these cheaper prurple drives seem to be more reliable than their higher end ones. The Blue drives were rock solid back in their day...but those days are gone.

Use it for it's intended function & it should perform exactly as designed.

It is a surveillance drive for NVR applications. I am assuming that anyone who knows the difference will understand this & the different build construction of different drives. It is quiet, no obvious noise, I have it running in an Amcrest brand NVR which it fit perfectly, screw holes lined up well, the cable connectors fit perfectly. I cannot measure the temperature during operation, but the NVR does not run hot or even warm, so that is a good sign to me. Longevity - It has not been running for very long, but the WD specs give an expected life (mean measured value, I assume) so I expect it to meet the mean life expectancy. Anything past that is a bonus. Use it for surveillance & it is fine, these are typically important pieces of stored data, but not normally mission critical, if they are, they you are probably an IT expert & you know what to do to back them up anyway (I am NOT an expert, I just have enough knowledge to be dangerous :-)....) Overall I have had good luck with different WD drives over the years & I expect no less from this one I did not get paid, reimbursed, of given anything for free (never do as I am not important enough online!) so you are getting my own unbiased, honest opinion & nothing but that. :-)

WD PURPLE 1TB HARD DRIVE

The WESTERN DIGITAL PURPLE was the most recommended hard drive for my ZMODO NVR Works great, no issues. ZMODO 8CH 1080p HDMI NVR with two ZMODO 720p Indoor Dome Cameras Model KC-100X Home Security System It did not come with a hard drive installed So I also purchased a purple WD HDD to install Only drawback is that it only supports Zmodo & Funlux cameras. Cameras should be IP/Network-Wired Still trying to figure out how to connect my Wireless cameras as one connected itself when I set the system up.

Great for NVRs

This drive is designed for constant write duty without spinning down. This mainly happens in video recording systems where video is constantly dumped to disk. This comes at a cost of seek and random access times (reading multiple files from various areas at once is slow). If you are looking for backup, media storage, or network storage, look at the WD RED drives. They will perform better in those settings, and are significantly cheaper. The drive is very quiet compared to many other drives. There is no loud clicking noises, or audible spin up sounds. I have some WD RED drives next to this system for network storage, and this drive is significantly quieter than those. I also have some Seagate NAS drives, but they are so loud I can't even use them in a living space. Anyhow, this is a great drive. It was installed in a generic low cost Network Video Recorder (Hisilicon Hi3520D) and it runs fine. Most low to middle end DVR/NVR systems use this chip family and the same software, so this should be compatible with them all. The drive has been saving 4x 1080p streams 24/7, and it has done fine so far through 8TB+ of looped writes over the past few weeks. The drive does run quite hot in a small enclosure, and most NVR systems do not have good ventilation. To fix this, I just bolted a 140mm fan to the top of the recorder after cutting a hole. This keeps the drive running around 30-40c instead of 60-80, as well as provides cooling to the NVRs processor (which was crazy hot and didn't even come with a heat sink). Most NVRs have a dedicated 12v connector for an optional fan, but if they don't you can always get power from the 12v barrel connector or the 4 pin HDD connector.

Surprising performance!

My son's WDC 2TiB drive had gotten full so he wanted 2 TiB more. I also needed another drive for my own backups, but for me 2 TiB was enough, so I bought this WDC 4TiB drive for him and took his old 2 TiB drive. Since his "old" drive was a 7200 rpm and the new one was 5400, I expected a slight performance loss for him. I was wrong. The new drive is fast and snappy. Opening a program seems to happen instantly. The drive "feels" faster than the 7200 rpm drive. It's quiet too. I don't even hear the slight sound that head seeks make. 100% satisfied. My only regret is that I didn't use this drive for my computer!

Perfect long-term recording solution for your DVRs.

Has worked fantastically in the Amcrest DVR it was installed in, providing 3 months of recording from (3) 3-Megapixel cameras 24-7. No issues, looks like it will last a long time. very happy, highly recommended. Remember, this is a low RPM drive, so backing up footage might be slow, but allows the drive to last much longer.
