About WD Purple 4TB Surveillance Hard Drive
Overall Feedback:
93% positive
89% liked its seamless compatibility with multiple systems
Most low to middle end DVR/NVR systems use the same chip family and software, so this hard drive should be compatible with all of them.
94% appreciated its quiet operation
I have noticed that this drive is significantly quieter than others I have used.
75% liked its low power consumption
I designed this drive for constant write duty without spinning down, which is a feature related to power efficiency.
89% found it to be extremely reliable and durable
I have been using an 8 TB Purple drive in a video surveillance recorder for the last 2 years 7 months and it has performed flawlessly.
I have had many WD drives over the years and have never changed brands. I have had more WD Caviar Blacks than I can even remember and they all worked great and silently and still do.
I see no issues and it appears to have a long lifespan.
95% praised for its advanced security features
I was looking for a drive specifically built for write-heavy applications like the UDM Pro Unifi Protect function for security camera footage and this drive fit the bill.
I recommend the PURPLE model for security cameras because it constantly records video.
It's important to get a hard drive that is properly rated for security system tasks. Using any off-the-shelf hard drive will result in serious issues. This brand and model have done an excellent job so far, recording 24/7 for over a year now.
81% appreciated its fast read and write speeds
This drive is very quiet compared to others and has no loud clicking or spin up sounds.
I am using the internal hard drive with Dahua NVR5216-16P-4KS2 to record 30 Mbit/s of video data and up to 60 Mbit/s with motion detection.
I have been using an 8 TB Purple drive in my video surveillance recorder for the last 2 years 7 months, filling it completely and overwriting every week, and it has performed flawlessly.
85% praised for its massive storage capacity
I plan to buy another one to make it a total of 16TB of storage space, which will be enough for a month of 4k video recording.
