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

Good product at best price

Super easy to swap out!

Gostei do produto ser original. O produto chegou rápido, bem embalado, com plástico bolha e descrito a mensagem FRÁGIL.

The drives a piece of junk. DOA. The motor doesnt even seem to spin. It was purchased supposedly new from HardDriveGeeks through Amazon.

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

Working perfectly

Nulla da dire fa quello che deve e non costa tanto

Lo use para grabar en las cámaras que se encuentran en la escuela, me sirvió muy bien

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!!

I was able to replace my failed HD in my UDM Pro with this 6TB WD Purple hard drive. I did not have to do anything special, just install it. I still retrieve my videos as quickly as before.
