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 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.

Don't have any strong complaints about the drive itself. It has worked well as do most WD products. Warranty support though is terrible. The drive died (which drives sometimes do) and I relied on the WD warranty to replace the failed drive since it was still under warranty. After days of back and forth "The drive makes scraping noise when you power it up." "Well have you checked the cable?" and so on they FINALLY decided that the drive needed to be replaced.That started on 5/1. It is now 5/23 and I finally have confirmation that the replacement has been shipped and should be here by 5/29. An entire month to replace a failed drive under warranty!!!

I contacted them and had the replacement drive 4 days later.While WD offers a 3 yr warranty I'm seriously considering buying all my future drives from the used drive company. Only a 2 yr warranty be replacement within 4 days as compared to a MONTH for WD.

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 ... MoreI purchased this as a data storage/backup drive for my desktop PC. My main drive is a1TB NVME drive.

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.

Quality Storage for Security Cameras
30 November 2023

This drive from Western Digital was one of the few to show up in my research, that provided the feature and design points I was seeking.Offering a durable lifespan, with the concept that it's under 24/7 use of writing, it's more than satisfactory for a local home installation of cameras. The large 4TB Capacity also ensures high quality or multiple camera feeds will be stored far longer before being overwritten or requiring deletion.Utilising a common SATA interface and CMR recording, your speeds are not harmed or limited in capacity for the hardware while maintaining good compatibility with past and present hardware. The notable 256MB Cache also helps accelerate the workload and keep a sizable buffer for incoming streams.It's also shockingly quiet while under ... MoreThis drive from Western Digital was one of the few to show up in my research, that provided the feature and design points I was seeking.Offering a durable lifespan, with the concept that it's under 24/7 use of writing, it's more than satisfactory for a local home installation of cameras.

There are also accelerometers to help the drive predict and counter any vibrations or movements that'd otherwise throw the head off track, ensuring a more consistent performance.
