Western Digital 3TB WD Purple Surveillance Internal Hard Drive HDD - SATA 6 Gb/s, 64 MB Cache, 3.5" - WD30PURZ

Works fine in my Swann DVR was a breeze to replace and is vey quiet.

My 4 1/2 year old Directv Genie`s hard drive was failing. Freezing, pixilation, it was well worn from constant use. The older model Genie HR54`s have an eSata connection for connecting an external hard drive. While there are complete externals available, the hard drives installed are most likely standard desktop units. These purple`s are designed for constant power on read/writes, and 5400rpm models run cool. Speed is sufficient, 7200rpm models not needed for DVR`s. I purchased a used G-Technology G-DRIVE 3.5" external enclosure minus it`s hard drive. Popped in a 2TB WD Purple, and for around $100, a complete unit was had. Double my original capacity too. Once connected, the Genie automatically formatted, and configured it. The internal hard drive is now incapacitated, the external taking over. It`s quiet, quick, and all the issues I had have vanished!

I have a Lorex NVR for recording security footage. After just a few months the included HHD in the unit died without warning. It was a complete crash. The device was under warranty and the company would not replace the drive, but rather said they would replace the entire unit with a used/refurbished unit and that it would takes weeks. I decided to keep the device and just replace the drive myself so I wasn't without a security system for that long. This drive was on sale and is more than twice the capacity of the other brand of drive it replaced. It is extremely fast when searching for past security footage. If you are looking to replace a security system drive be sure to get one that is properly rated for this task. You can't just use any off the shelf hard drive or you will run into serious issues. These specialty drives exist for a reason, and this brand and model have done an excellent job so far, recording 24/7 for over a year now.

Very easy to upgrade my Lorex NVR Model N843A8. It fit perfectly and worked like a plug and play device. It only requires a quick format after letting the system fully boot up. It started out a bit noisy but quieted down about 20% after a few days of recording. I discovered most of the noise is being made is due to the hard drive being directly mounted to the NVR case which is thin sheet metal that actually amplifies the natural vibration and clicking that spinning hard drives make. I believe this could be resolved by a soft mount, stiffening the case and rerouting the ground the hard drive makes while in contact with the NVR case. I blame the noise on Lorex and not the hard drive for this reason. The only reason I gave it 4 stars instead of 5 is because playback doesn't flow in sync with multiple cameras or at real speed, which makes calculating vehicle or aircraft speeds between markers impossible. Sometimes the recorded video playback of multiple cameras do not sync in time and may be separated by just a few seconds. I do however believe this may be a firmware issue with the Lorex NVR but have no way to prove it other than to say the original hard drive did the same thing and that's mainly why it was replaced. It was a good value for the money until the 24 to 36% Trump tariffs kicked in. As an alternative storage method I highly recommend the Samsung 870 QVO SSD.

This was the right size HDD at the right price to add to my NVR for my home surveillance system. 2TB gives me enough space to keep everything running with no issues. Works great for a 1080x4 camera system, hopefully for a long time. Recommended if you need robust storage that will be overwritten constantly.

When my 1TB Sata drive in my Cobra 8 channel surveillance recorder went out I decided to give this 2TB drive a try and so far it seems to have been a great choice. I unplugged the power and Sata cord and while holding upside down removed four screws holding HD to frame. I reversed the process and fired it up and got a message to format drive which took less than a minute and my cameras came back up. I was shocked I never had to redo my settings or create new password, the recorder was set just as before. Now we hope for longevity.

I bought this item because the hard drive on our Hikvision NVR was failing already. The installation took maximum 5 minutes, it was an easy plug n play. For the price you can’t beat it!

I purchased this as a data storage/backup drive for my desktop PC. My main drive is a1TB NVME drive. The data drive I use for movies, songs, and backups and digital images. Since I am not booting with the drive I don't care about raw performance, nor will I pay for it. With that said I am VERY happy with this drive. It only spins at 5400 RPM, so the access time is slightly slower, but it makes no difference to me. Maximum transfer rate is nearly 200MB/sec. High capacity drives have dense platters and are able to pull data faster. I am a Nazi for eliminating extraneous sound and used to keep my drives inside enclosures to reduce sound. My quietest drive to date is the Samsung HD 503HI, and this is even quieter. I have several large case fans spinning slowly and if I turn them off I can ever so slightly hear a faint humming or click, but otherwise I hear NOTHING. This is my first WD drive (have always used Samsung). I cannot speak to the drive's reliability as I've only had it for one month. It is labeled for "Surveillance," so if it's meant to be running 24/7- 365 it is meant to get use in commercial/industrial environments. I think everyone with a desktop PC should adopt this system. It is very easy to backup anything important- save it to your C: drive as well as your backup E: drive or whatever. If one your main drive goes kaput you have the backup to pull your saved data from. You can use flash drives for additional redundancy and portability, but in my experience they are not so reliable.

منتج مستعمل وحالته رديئة جدا

Muy buen disco, muy silencioso, no hace nada de ruido ya que eso es importante en un DVR. Mi disco anterior hacía ruidos como de tortillería.
