Western Digital 500GB WD Purple Surveillance Internal Hard Drive - SATA 6 Gb/s, , 64 MB Cache, 3.5" - WD05PURZ (Old Version)

Packed very well, fired up with no issues, incredible value

My 6TB WD PURPLE lasted 5 YEARS + 1 DAY (not kidding here), spinning, and reading & writing, NON-STOP in my NVR. Though not my first WD HDD by far, my decision to invest in WD reliability was well worth it! I've been using only WD HDDs for over 30 years; except maybe when a OEM had built a PC, DVR (etc) that shipped with something else. I also spec'd WD HDDs into a Universal Computer design subsequently fielded in Mission Critical Systems onboard virtually every "war-fighter" ship in the US Navy. In these systems the HDDs had to endure the torture of shipboard Shock, Vibration, Temperature Extremes, and Humidity; and while those HDDs may not have been spinning 24/7, they never caused system reliability issues. No, I don't work in the industry any longer and this is NOT a paid advertisement. I'm just amazed that such a complex mechanical device could be so BALLISTIC, and grateful to be able to say THANK YOU WD!

EASY - VERY EASY TO INSTALL!!!Before handling the hard drive, before you take it out of its package - you MUST DISCHARGE ANY STATIC ELECTRICITY FROM YOURSELF, YOUR WORK AREA, AND ITEMS TO BE USED!The best way to do that is to purchase a ground strap for your wrist. There's a velcro strap that you strap around your wrist and it's connected to a spiral cable which extends to a alligator clip. The alligator clip you can attach to a piece of metal or something going to the ground and that'll discharge any static electricity from your body. They also make anti-static mat that you can work on. Some people take anti static fabric sheets and rub them on themselves or they rub their hands on metal to make sure they discharged the static electricity from their body. Just don't purposely Shuffle on carpeting or known areas of static electricity build up cuz this can damage your equipment!So I opened up my Envy our case, after unplugging all the power cables and video cables. From there there are four bolts on the bottom holding the existing hard drive to the bottom of the case. Once I remove those, the hard drive slid straight out from its connector. The new hard drive the Western Digital purple 6Tb plugged in very nicely! I reinserted the four screws underneath and put the top of the case back on, plugged everything in formatted the hard drive and it's been working beautifully!I'm using this to increase the capacity of my Swann 8580 series NVR surveillance system. It won't allow anything larger than 6 terabytes and it came with a 2 terabyte hard drive.Instead of transferring files from the m v r to an SD card or a Micro SD card then to an external hard drive or computer, I just decided to go with a larger hard drive and when it's full have another one ready to replace it and store them safely then I can always have the original. And then I'm able to put that back in the NVR and use all the features of the NVR to examine the video, which you lose when you download the videos and transfer them. And it takes a very long time to transfer 122 terabytes of information from the NVR to a micro SD card or an SD card then uploading to an external hard drive or computer. And that way you also have a recording of everything the surveillance system captured in case you missed a recording and now you no longer have it. And then it gives me time to review recordings and then I'm able to reuse the hard drive after formatting it.

I recently added a NVR recorder to my security camera system, instead of using a computer server and I am using these to expand my NVR’s capacity, since it can handle four 10TB drives, I got two of these 10 TB drives (direct from Amazon) to go with two 2TB drives that I am already using in my security camera recorder. The 2TB drives have held up well to the constant recording and these 10TB are doing fine as well. These drives have added several weeks of past recording data, due to their large capacity. The hard drives have a good 3-year warranty and the WD drives have been very reliable. These hard drives are a bit pricey at 265 per drive, but not bad if you consider per TB cost and the amount of recording space these are capable.4.5 stars

bought 2019, died 6 months after warranty expired

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

I ordered two of these 10TB drives for replacing the a 4TB drive in a surveillance system recorder for continuous live recording of 16 4k cameras. The drives arrived timely and in a sealed anti static bag. Devices were installed and the DVR start recording without any issue. This will give the organization an estimated year+ video. These drives are in a continuous recording for few weeks and is doing its job 100%. I will recommend and rate a highest rating for providing what it said to be providing.

I like to shop the other vendors deals if available. I brought this "open box" for my security system. Works like a champ and what a deal!!!
