Western Digital 4TB WD Purple Surveillance Internal Hard Drive HDD - SATA 6 Gb/s, 256 MB Cache, 3.5" - WD43PURZ

This is a very reliable drive; I have three and they work great in both my camera system and my computer. Since it is basically plug and play there is no issues with installation. These are not the cheapest drives but then again you get what you pay for, and these are definitely worth the little extra cost. They seem to last forever, got one that is 6 years old and is still working without a hiccup. Since these are a 4 TB drive, they actually hold about 3.86 TB of data and are pretty quiet compared to other drives I've had in the past.

still working good in dvr a few years later.good brand, reliable.

My first HDD was a Seagate 1-TB that came with my Hiseeu NVR. The Seagate lasted just over 1-year and Hiseeu would not replace the HDD unless I gave them a 5-Star review which I was not going to do just to get a free Seagate 1-TB HDD. Plus I would never give a 5-Star review on a junk system that I was sold so instead, I bought this Western Digital 3TB not knowing if it would work but once I installed it, it did work right away without even formatting it. I still did format it eventhough it worked as soon as I plugged into my SATA/ power cables. This product does work. It is easy to install. It's easy to format and it was delivered the next day after ordered. I highly recommend this product for your surveillance camera system. It also has a lot more storage than the 1-TB that comes with the Hiseeu system. This HDD is quiet and I cannot here it at all. It has only been installed for about 48- hours so time will tell how long it will actually last but as of now I am very impressed overall. If something goes wrong with it over time I will update my review but for now 5-Stars.

I bought this for my Reolink NVR as extra storage for surveillance footage. It was highly recommended on many Reolink forums and one of the HDDs suggested by Reolink themselves. At first, my NVR recognized it but for way less gigs than it was labeled for (I bought 4tb/4000gb). Then at reboot, it wouldn't show up at all. Different cables didn't work and Windows couldn't do anything with it either. It was shipped only in thin, sealed plastic with a label on it, no padding at all. It was probably thrown and dropped multiple times before it was even tossed in my package lock box. I ordered a 4tb Seagate Skyhawk HDD instead - it was shipped in the same sealed plastic but in a cardboard box with fitted cardboard framing inside to keep it from getting jostled around. It was shipped like they cared about the product and wanted it to work for me! I plugged it in, formatted it and rebooted the NVR - IT WORKED! Started writing data immediately! No fuss required! I'm sure this is a great brand, I'm just sad that I ended up with a dud and will be returning it :(

Perfect replacement for my Swann 4K 8 camera Enforcer surveillance system DVR. Installation taking the DVR apart was10 minutes. Formatted this new 4TB Hard Drive & back in the saddle up & running. Hope it lasts, the original Toshiba 2TB lasted 3 1/2 years.

Bought one of these for my Ubiquiti setup and it's constantly emitting a muted clicking sound. Reminds me of an old wooden house creaking. Outside of the noise, it seems to work fine. DO NOT PURCHASE IF YOU'RE USING THIS IN A ROOM WHERE YOU WANT PEACE AND QUIET

Work good for my camera system

Came as defective, the HDD can't be started. It is either defect from factory, but likely mishandling by Amazon. The packing came ok-ish but with a lot of deformations.

Fungerar som den ska och den känns relativt snabb.
