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

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

I installed this in my Reolink 4K 8 channel DVR box. My box did not have the external hard drive port, therefore, I had to install this inside my box IN ADDITION to my factory hard drive. The factory hard drive was 3 tb, and this was 6 tb. I had 8, 4k cameras and 2 1080p cameras and was getting about 4 days of history on my 3tb. I'm now getting nearly 13 days of history. Installing this in my DVR box was was simple. I recommend doing a physical shutdown on the interface, and unplugging all the cords. Then, 5 or 6 phillips screws will remove the cover. I ended up robbing two of the four, factory hard drive screws so I could mount this new one in my box. Then, there are the data and power cables already in there, just hook them up. I hooked up all the cords, then powered the unit on. I had to go into the interface and under storage, this drive was listed, but I had to click on "format" for it to start working. Once I did, bam... additional storage. If you're installing this in a reolink dvr, be sure to check their website. I found an article about their dvr's and maximum storage.

Installation was easy and this worked flawlessly right out of the box. I know this won't last as long as a computer hard drive as this works 24/7 and 365 days a year, the original factory drive was a different brand (Sea something) and lasted about a year before having issues. I believe this is a good value for the money and formatting this was a breeze. The drive is western digital and I have always had good luck with WD drives as their drives have always been quality. The noise level did not seem excessive considering it is always writing data files.

I have used several of these in DVR's over the years and have never had any issues. Some have been running 24/7 for 5-6 years and are still working fine with good SMART status. If you use this in a PC, you will have to go to "computer management" and initialize the under "GPT" if it is 4 TB or larger. I only briefly used it on windows to verify it is a new drive and do a speed test. It is new - 2 power on counts and zero hours of power on time. I was REALLY impressed with the read/write speeds. Sequential was on par with a SATA SSD drive! Picture of the speed test attached. The drive was empty during the test, so actual speeds will be lower once the drive fills up.

I bought this to replace an older drive that is used for constant writing and reading. The older drive performed better by a little bit. This drive is okay, but definitely not for the 6gb/s speeds. It was on sale at the time, so I bought it on a whim, almost as a gamble. It's so so.

Buen producto este es el tercero que compro, tengo un negocio en mi país Nicaragua y nunca se me a perdido información o videos de las cámaras de seguridad, si buscas respaldar tus videos de cámaras de seguridad esta es la mejor opción.

Doing its job

Used/Using it in a Tigersecu Security System 16 Channel DVR. First time I've ever installed a hard Drive so I was initially a bit concerned but instructions were clear and it was actually pretty simple. It doesn't make any sound at all and working fine with no issues for 3 years now. I also like the amount of storage capacity.

I used to visit the shop in Sim Lim Square for their comprehensive range of items on sale. Now i can order online and delivery is so fast at best price on the market

Como siempre está marca cumple con excelente calidad.

جيد

Compleet onbereikbaar geworden zonder SMART waarschuwingen of errors. Maakt een raar ratelend geluid. Lijkt erop dat de arm-aansturing stuk is. Uiteraard nèt buiten garantietijd.

WD never lets me down, quality drives at an affordable price point even though HDs are ridiculously expensive these days. My first set of surveillance drives for an NVR and they're rock solid.
