Western Digital 2TB WD Purple Surveillance Internal Hard Drive HDD - SATA 6 Gb/s, 64 MB Cache, 3.5" - WD23PURZ

WD has been in the drive business for ages. Drive is quiet, installs easily and works well in my NVR

Bought the 6TB hard drive for the home security and its so worth it. This purple model is specifically made for recording 24/7 which is great and the size is also good, fits perfectly into my VCR recording system. Very well spent and such a great investment. Works perfect for it.

I am currently using this drive in my computer, and it works well. This can be used in systems too, not just DVRs. I am able to store bigger files (gameplay recordings and shared folder for virtual machines) and games that don't require constant/heavy texture streaming.

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.

This is the second faulty bed (WD Purple HDD, 8tb) I have received. I've used Western Digital for years and never had this kind of experience.The first one appeared to be new in original Western Digital packaging. It failed to spin up and would not be.recognized by my system (Reolink RLN36 NVR). It was returned and I reordered the same part number again.For test purposes I repurposed a used Western Digital Black 1tb drive to verify that the system was not faulty. It performs as expected, so I know my system is not the problem.The second drive was not shipped in any kind of factory original packaging. A bubble wrap bag was the only protection, other than the anti static bag immediately around the drive.Upon power up this drive spins up and the heads repeatedly go through a cycle that is far louder than normal - the type of noise a drive makes when failure is imminent - and it never gets recognized by the system.As of this writing my return of the first drive has not been processed and now the second one does not work. I'm out almost $400 of my money and still can't use my system.I plant to buy from a distributor that will send me a properly packaged drive, handled in the correct way before it reaches me. Apparently Amazon and this vendor are not up to that task.

Works great but as another reviewer said mine also has a creaking sound that sounds like a wooden rocking chair on an old wood floor. Thinking about going with a different brand because the kids are saying they don't like the noise.

Installed around a year age and still working great fit prefect and is very quiet great value over a replacement unit and simple to install

Been running 24/7 in my NVR system for months without a hiccup. No noise, no overheating, just reliable storage.✅ Pros: Designed for constant use, very quiet, big storage❌ Cons: Not for regular desktop use (slower read/write)💡 Tip: Use in surveillance systems only — it’s built for write-heavy workloads.
