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

Only showed up as 5.5TB, hope it last a year?

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

Does what it is supposed to

this hdd is very noise sounds

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

Nulla da dire fa quello che deve e non costa tanto

Used this product as an external drive to my reolink dvr. Worked really well. Just have to use an external housing with esata connection

I needed to replace the 2 TB hard drive in my NightOwl 3 MP Surveillance Camera system, because the original hard drive quit recording after three years of service. I was on the fence about whether to invest my money into replacing the failed hard drive with this new Western Digital 4TB Purple hard drive, or spend a little bit more money, and replace the entire system. Since I’m not a Computer Tech by any means, the thought of ignoring the manufacturer’s warning labels against opening up the DVR case, and then then having to poke around with a screw driver, to uninstall the old, to replace with it with this new one made me nervous. I understand hard drives to be fragile, and the thought of handling these hard drives during the swap, was scary to me. I couldn’t afford to mess it up. Much to my surprise, it was an extremely simple task. I did watch a utube video on it beforehand, which did help me. It took more time to unscrew the DVR case, than than it did to swap out the parts. It’s just a matter of unplugging the old one, and plugging in this new one. Close the case back up, power on, and follow the on prompts in the screen. This 4Tb Western Digital Purple hard drive made especially for surveillance applications, installs itself from there. It was quick. It was easy, and it has performed. The best part is that it saved me money from having to purchase a whole new system. I’m very happy with my purchase. I believe it was money “well spent”, and I can highly recommend this Purple hard drive, with confidence. Thank you, Western Digital, for producing a quality product

This 6 tb surveillance hard drive is working well in my dvr. I get about 2 weeks with 8 cams on this size HD.

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