Western Digital 18TB WD Purple Pro Surveillance Internal Hard Drive HDD - SATA 6 Gb/s, 512 MB Cache, 3.5" - WD181PURP

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.

I purchased three of these hard drives. One came to me. It didn't function. About a month later I received a new one.

I bought two of these for my NVR. One plugged in and worked just fine. The other was DOA - NVR reported an error and it wouldn't spin up. Eh, no big deal, it happens, I returned it to Amazon and they sent me replacement. This one was ALSO DOA. At this point I wondered if maybe my NVR backplane had an issue, so I tested the drive in other computers; nope, still dead. I switched around my existing NVR drives, and that slot works fine. So, two dead drives out of three. I then came here to check reviews, and I see many 1-star Dead-on-Arrival reviews, with many people apparently not checking until after return period (that sucks!). If you want to take the gamble, just be sure you check your drives right away when they show up!

No issues so far! I am using this drive in my Unifi UNVR and it's been working great since I made the switch from housing my camera recordings on my Unifi Protect with 1TB HDD, which previously frequently would become unreachable and require formatting from time to time. With this much larger drive meant for surveillance systems, I currently have 7.92TB/13.9TB used and I already have 41d worth of recordings for my four 4k cameras. I am VERY happy and with this purchase!

Works find in Hikvision NVR, gave lots more storage space and is quiet. Replaced a nearly 10 year old drive that I figure would fail sometime soon.

The biggest issue I faced was the inability to order 4 drives as Amazon limited the number of drives to 3 With the limited stock I almost did not buy them, but was able to get my wife to order the 4th drive Sadly the drives 24hrs latter had dropped in price, a little frustrating but a fact of life in todays market The drives turned up in a paper bag that was split, the box’s were a little banged up, but the internal packaging probably prevented any serious damage. I hot swapped the 4 drives & the array built itself, taking about 2 days The performance of the system when loading detections has been improved but at a cost of more noise The 7200rpm drives are significantly noisier than the 5400 rpm which may result in the system being moved to place where the noise is not a problem So all told happy with the choice at the moment, but will come back to update this review if anything happens that prospective buyers would be interested in

Good quality i recommend you to buy it

Not working in all I bought 2 NVR And non of them work!! And this not the first time !! Don’t buy

Buena marca para almacenar video vigilancia

Does a lot more noise than the drive it is replacing. Do not install in the same room as you work in.

boa capacidade e facil instalação

Fácil instalação, foi só trocar pelo antigo Notei que é mais rápido na hora de ver as filmagens.

Decent storage for 4k 10-15 cameras
