Western Digital 18TB WD Purple Pro Surveillance Internal Hard Drive HDD - SATA 6 Gb/s, 512 MB Cache, 3.5" - WD181PURP

This is one of the many WD Purple label Hard disks that I have ordered. They are great drives, very reliable and fast. I use these WD purple drives in my NAS drives. Just install and forget about them ... :-) From my past experience, these drives will go many years in always on situations without a hitch. Last NAS I had some HD running non-stop for 10 years. Only upgraded the NAS for more speed and installed WD hard drives again for maximum capacity and their bulletproof reliability. Only caveat is they have this continuous fairly loud "thumping" sound. I just ended up placing the NAS drives a little aways, so that the noise of the HD's would not disturb. Highly recommended!!!

These robust, high speed, "24-hour video recording" 18TB HD's make for a terrific solution for churning out monster-sized file renderings from 3D software (Maya, Houdini, etc). The things are absolute beasts, and their resilience and beefiness is exactly why I use them for my "small" personal render farm (one 2-disc 36TB RAID-0 for smaller renders, and a 5-disc 90TB RAID-0 tower for bigger renders) in my home office. Sure, I could have gone for the "Black" version that a lot of gamers prefer (if they are using SATA instead of SSD), but these drives are larger capacity with the same speed, and built to handle even more stress. Should last me several years, no problem, but I will collect a couple more to keep on hand in case (or when) any of the originals fail...Eventually, yes, I'll likely go all-SSD in the future, but not until they are at the same price-point, with the same-or-greater TB size, and equally "indestructible". Brilliant slabs of hardware.

exactly as expected. using for nvr storage. worked great.

Should be zero stars because neither drive worked when I went to replace the old ones. Neither worked for a while and quit, they just failed right out of the box and this isn't the first 18TB from WD that failed. Another one failed the same way month or so before this. I found that one didn't work right away, but didn't get around to testing these two until after the refund date expired...

Not compatible with certain nvr devices but smaller ones should work

I have purchased 5 WD Hard Drives over several years for different electronics and all have performed exceptionally well. Reliable, quiet operating units. Until they give me a reason not to use, I will continue to purchase them.

Great for long term reliability and size for camera storage. Quite when running and Great speed of transfer.

I am using this in a Ubiquiti UDM-Pro for my camera storage. It is supporting 2 4k cameras, 6 2k cameras, a doorbell camera, and another wireless 2k camera. With all of these devices I am getting almost a months worth of storage when there is 24/7 recording. Great value for the amount of storage.

I recently purchased a hard drive and I must say, I am extremely satisfied with its performance and reliability. This hard drive has proven to be a worthy investment, providing ample storage space and good for security camera

Item was dead on arrival, yet to receive a refund. Buy you HDD elsewhere.

You can get them cheaper at your local computer store or from WD, but amazon is convenient so - shut up and take my money.

Liked how fast service was on delivery, and item very well packaged. Products is very well efficiently, running. Thank you.
