Western Digital 4TB WD Purple Surveillance Internal Hard Drive HDD - SATA 6 Gb/s, 256 MB Cache, 3.5 - WD42PURZ

It feels like my system is running smoother faster and obviously more storage I think it was worth the upgrade especially considering how much you invest in your camera system!!

somehow the drive only use for less than a week, and start undetected and making noise, the drive is defected., replaced order and will see how long it will last on the replacement order

I bought this drive to use in my Ubiquiti Dream Machine Pro. I have four cameras hooked up to it, and its run perfectly for the past two years. When the day comes I need a replacement, I would definitely buy this again.

Não está em uso, apenas testei se o pc reconhecia o hd. Reconheceu.

Good product at best price

Great

Replaced a 3TB drive that went bad after 4 years with this one. Easy to install.

I needed more storage for my NVR, the manufacturer suggested another brand but had not tested this version. I saw that it was a performer in the testing data and after install I have had zero issues. The NVR interface was able to increase my storage and I am able to record much more.

Precio y calidad

Actually, used in a NVR to record 4 video streams but the needs are the same as for a security system. NOT made in China so it should last. Never get any HD made there. Any other Asian country but not China. Thailand, Malaysia, Japan (of course), Korea, Singapore, Vietnam but avoid Chinese ones.
