Western Digital 4TB WD Purple Surveillance Internal Hard Drive HDD - SATA 6 Gb/s, 256 MB Cache, 3.5 - WD42PURZ

This plug and play replacement for a failed NVR hard drive was exactly what I hoped for and did not disappoint.

I install home camera systems. Most home recorders come with 1tb drives. With 4 cameras running 24/7 that is only a few days of recording time. I installed this in a 6 camera system and it extended the time to 25 days.

Works great for my video surveillance system. Easy to install. I would recommend it.

llegó muy bien empacado y a tiempo guncionando muybien

Ordered hundreds of HDDs, never got one just thrown in a box like this before. A few weeks of use and the drive is failing. Just going to RMA it with Western Digital, at least they ship drives properly.

Good solid hard drive. If it performs as well as the other WD drives Ive bought over the years, I will be very happy.

I bought this drive to use in my Ubiquiti Dream Machine Pro. I have four cameras hooked up to it, and its run perfectly for the past two years. When the day comes I need a replacement, I would definitely buy this again.

Almost a year ago, I built a dedicated desktop computer using an Intel i5 CPU, 32 GB of memory, a NVIDIA graphics card and an upgraded power supply, to use exclusively for my 4 HD WiFi PTZ Surveillance Security Camera system. Its a Windows 11 Pro based computer, running Blue Iris 5 software 24/7. The main Hard Drive is a Western Digital SSD Blue 1 TB, but I was running a competitors hard drive as a secondary drive for storing captured videos and photos from the cameras. Performance was so so. When I went to pull up one of the individual folders for one of the cameras to view photos and or videos, it took a while to load , especially when I wanted to scroll down or up. I could also hear that secondary drive running. It wasnt super loud, but still annoying. I installed the new Western Digital Purple Surveillance Hard Drive, 4 TB, 256 MB cache, and let me tell you, the difference between that hard drive and the one it replaced is like night and day. The WD Purple Hard Drive is FAST and its QUIET. There is no lag time when opening a folder for anyone of the cameras to view photos or videos. Setup was a snap using Windows 11 Disk Management. I already had WDs Dashboard software installed, and it recognized the new hard drive right away. Formatting was quick and easy, and so was creating and naming the new folders that I needed for Blue Iris 5. Make no mistake, the WD Purple Surveillance Drive is a mechanical and NOT an SSD drive, but you would never know it because of how well it performs. According to WD Dashboard, it is NOT running hot. The hard drive is rated to handle up to 64 cameras at one time. Im running high quality Amcrest cameras, and this new WD Purple hard drive was a good match for my system. I would have to say that the WD Purple Surveillance Drive exceeded my expectations. It was money well spent and the price was good too! I highly recommend this Hard Drive for anyone using a computer for their surveillance cameras, or even for using it in a DVR in place of a computer. Thats exactly what it was designed for.

Because of reviews from buyers complaining that the drive they received wasnt new, or was packaged carelessly, I give you my comments. This review is specifically about a 4TB WD Purple WDPURZ 3.5 drive designed for 24 x 7 systems and sold and delivered by Amazon. It was made in Thailand in August 2022, four months ago. It was in a pristine anti-static bag, sealed, with a desiccant pouch inside. The drive was supported by a plastic anti-shock nest at two sides that isolated it well, inside a strong cardboard box. This is a very common apparatus I see when I buy new drives. I suspect its engineered to guarantee that no matter who does what with the package, the drive will never be disturbed. I cant say anything about the working of the drive; we all know theres a very high probability it will work perfectly and last a long time, and that prediction will apply to the one you buy too, even if I get incredibly unlucky and mine bursts into flame the moment I plug it in.

Works great
