    PRODUTO DE ÓTIMA QUALIDADE !

    I needed to replace the 2 TB hard drive in my NightOwl 3 MP Surveillance Camera system, because the original hard drive quit recording after three years of service. I was on the fence about whether to invest my money into replacing the failed hard drive with this new Western Digital 4TB Purple hard drive, or spend a little bit more money, and replace the entire system. Since I’m not a Computer Tech by any means, the thought of ignoring the manufacturer’s warning labels against opening up the DVR case, and then then having to poke around with a screw driver, to uninstall the old, to replace with it with this new one made me nervous. I understand hard drives to be fragile, and the thought of handling these hard drives during the swap, was scary to me. I couldn’t afford to mess it up. Much to my surprise, it was an extremely simple task. I did watch a utube video on it beforehand, which did help me. It took more time to unscrew the DVR case, than than it did to swap out the parts. It’s just a matter of unplugging the old one, and plugging in this new one. Close the case back up, power on, and follow the on prompts in the screen. This 4Tb Western Digital Purple hard drive made especially for surveillance applications, installs itself from there. It was quick. It was easy, and it has performed. The best part is that it saved me money from having to purchase a whole new system. I’m very happy with my purchase. I believe it was money “well spent”, and I can highly recommend this Purple hard drive, with confidence. Thank you, Western Digital, for producing a quality product

    Broke after 15 days. Drive doesnt get detected in Windows or Linux. I get ntfs_pread failed: Input/output error in Linux and Disk1Unitialized Disk in windows. Return period was only 10 days and couldnt even return. Had to claim WD warranty for replacement

    Installed this WD Purple 4TB in my Lorex DVR (from 2016) that had a 2TB WD Purple. The drive doubled recording capacity while still keeping the performance. The newer drive has 256mb cache, vs. the older unit had 64mb cache, which means it would perform better on writing/reading, with lower heat and longer MTBF.. all in all the 256 MB WD Purple drive is a win win.. Must have if you are upgrading your DVR / NVR storage.

    I was able to replace my failed HD in my UDM Pro with this 6TB WD Purple hard drive. I did not have to do anything special, just install it. I still retrieve my videos as quickly as before.

    Hard disk 4TB specifico per videosorveglianza. Non è il primo che acquisto e spero che faccia la solita riuscita dei precedenti. Installato in un NVR risulta silenzioso.

The Right Drive for the Right Job. WD Purple drives are engineered specifically for surveillance to help withstand the elevated heat fluctuations and equipment vibrations within NVR environments. An average desktop drive is built to run for only short intervals, not the harsh 24/7 always-on environment of a high-definition surveillance system. With WD Purple, you get reliable, surveillance-class storage that’s tested for compatibility in a wide range of security systems, and some of our latest models (WD22PURZ, WD42PURZ, and WD63PURZ) have improved power efficiency. Exclusive AllFrame technology helps reduce frame loss and improve overall video playback.
