Review: facil instalação - boa capacidade e facil instalação Review: A workhorse of a drive. Great for Surveillance Camera Systems! 13 cameras, 3 Years and Counting... - I use two of the 18GB drives for stored video for two Blue Iris security camera systems in different locations. Zero compatibility issues with Blue Iris or two desktops (Lenovo Think Station & HP Elite work station) Both systems write direct-to-disk fast, with one handling 13 cameras, all recording constantly and the other handling 5 continuously. The system with 13 cameras has had the drive running flawlessly for 3 years now and the other with 5 cameras for about 1 year. I have no complaints about the noise level--some say they are a tad loud, but I feel they are reasonable for what they are doing. No problems whatsoever with either drive or system. I highly recommend for constant-write uses such as surveillance systems. The 18GB was overkill for my application but I wanted at least 30 days of backup footage in my system for all cameras and a few more in the future. They're a workhorse of a drive. ## Features - The WD Purple Pro HDD, with OptiNAND technology in 22TB(1), delivers big capacity in a drive engineered for advanced, AI-enabled, always-on smart video recorders, appliances, and servers. | (1) 1TB = one trillion bytes.
