Review: Works perfectly with my Unifi NVR - The Western Digital 10TB WD Purple Pro Surveillance drive is an excellent choice for anyone looking to upgrade their surveillance storage system. Built specifically for 24/7 operation, this drive offers reliable, high-capacity storage designed to handle multiple camera streams simultaneously, making it perfect for large-scale or demanding setups.

Its robust design, massive storage capacity, and performance under continuous workloads make it an industry-leading solution. Highly recommended for anyone serious about security and data integrity.
Review: Excellent and reliable drive. - I have a Unifi setup, with 4 WiFi cameras. I was using the Cloud Key Gen 2+ with the 1Tb included HD, but I was having alot of issues with pulling up footage, live views, lagging, etc, on the gen2+. But now I upgraded my setup to a Dream Machine Pro SE, with a Unifi WiFi 6 Pro Access Point, with this 12TB WD surveillance drive, and it works FLAWLESSLY! Make sure you buy a surveillance grade HD, other HDs like for a PC gamer build, they will fail within a few months, believe me, it’s happened to me. I get 120 days of continuous storage with my 4 WiFi cameras. All my issues were resolved! No lag, scrubbing is smooth and easy, live views on my local WiFi and on 5G on my iPhone using the Unifi protect app all work great now! It’s a FAR more reliable setup and I would encourage anyone who wants to use Unifi to go this route for your home security cameras.
