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

Works great for security system

Ordered hundreds of HDDs, never got one just thrown in a box like this before. A few weeks of use and the drive is failing. Just going to RMA it with Western Digital, at least they ship drives properly.

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.

Broke after 15 days. Drive doesnt get detected in Windows or Linux. I get ntfs_pread failed: Input/output error in Linux and Disk1Unitialized Disk in windows. Return period was only 10 days and couldnt even return. Had to claim WD warranty for replacement

Estoy muy satisfecho con el producto

This was a replacement for a worn out security camera HDD. Easy to install. It does NOT come with connection or power wires.

Funciona a la perfección, 4 teras me dan casi un mes de grabaciones, fantastico Cuento con 8 camaraspara referencia

Bought this at a great price, but came with bad sectors and no-functional

Did research on my NVR and is recommended either this one or the Skyhawk for about $20 more dollars I received the hard drive about 1 to 1 1/2 weeks earlier. Easy to install and no issues

I’d purchased a larger capacity drive for my UniFi UDM-Pro, which sits on the top shelf in my TV room. It was speedy, but so loud that there was constant noise over the TV unless at very high volumes. Switching to the WD Purple made that noise vanish instantly and it’s been just as good at recording my doorbell camera. If you need a reliable and above all QUIET hard drive, the Purple line is for you.
