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 ...

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.
