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

Genuine product.

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

so far, so good

Estoy muy satisfecho con el producto

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!!

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

Good solid hard drive. If it performs as well as the other WD drives Ive bought over the years, I will be very happy.

Works great for my video surveillance system. Easy to install. I would recommend it.

Exacto lo que buscaba para mí cctv

The HDD was very easy to install in my reolink NVR. I just removed the old drive and installed the new drive without formatting it. It was plug and play. The old drive lasted for about 4 years. Ill update this review if it fails anytime soon.
