Western Digital 8TB WD Purple Pro Surveillance Internal Hard Drive HDD - SATA 6 Gb/s, 256 MB Cache, 3.5" - WD8002PURP

I bought this beast to drop into my Amcrest NVR system because apparently, my house needed the same level of surveillance as Fort Knox. Spoiler alert: it works perfectly — and now my house is basically the Truman Show, but with better resolution. 🎥 Why I Love This Drive: 12 Terabytes of "You Saw Nothing, Officer" Seriously, it holds weeks of 4K footage from multiple cameras, including the one pointed at my driveway that’s mostly squirrels doing parkour. Purpose-Built for Paranoia Designed for 24/7/365 surveillance workloads. No naps. No coffee breaks. Just pure, tireless storage of every Amazon delivery and mysterious leaf blower incident. Plug-and-Paranoia Installation Installed in my Amcrest NVR like it was born there. No firmware drama, no compatibility tantrums. Just silence... and a blinking light of judgment. Cooler Than Your Ex Runs quiet, stays cool, and doesn’t randomly ghost you like a desktop hard drive shoved into a job it wasn’t hired for. 512MB Cache = Smooth Playback Rewinding suspicious backyard activity in crisp HD has never been this satisfying. Even if it was just a raccoon again. 🧠 Final Thoughts: If you're serious about home security (or just want to capture footage of your neighbor stealing your trash cans), this is the drive. It’s like a security guard that never blinks and never asks for a raise. Buy it. Install it. Sleep easy — unless you're worried what it might've caught you doing

Working great so far. I've preferred Western Digital drives for years. 5 year warranty is great with these drives.

Needed a larger drive for my security camera NVR system. This gives me about 26 days using 10 - 4k cameras. A little noisy while running, but not terrible. Great drive for this application!

Abolute trash! Supposedly a high end drive.. Straight out of the box sounds like its struggling to survive. Constantly clacking and banging. No drive spin sound just clicking, clacking, and bangs within the drive. No activity as its sitting inside an enclosure.

Worked great in our NVR. I installed two of these hard drives. We can now save over 2 months of video from 10 security cameras.

Not compatible with certain nvr devices but smaller ones should work

I have 4 of these in a Ubiquiti Unifi NVR recording 24/7 from 10 cameras for the past 2 years. Added an additional one recently. These are reliable and more quiet than the Seagates but a little pricier. Not a big deal if it's in the closet anyway though.

I previously ordered a Toshiba N300 16TB NAS 3.5-Inch Internal Hard Drive - CMR SATA 6 GB/s 7200 RPM 512 MB Cache - HDWG51GXZSTA drive for our surveillance system, but it was extremely noisy/clicky big time. I returned it and got this WD drive. It's extremely quiet for a drive of this size and so glad we switched!
