Skyhawk 4TB Video Internal Hard Drive HDD – 3.5 Inch SATA 6Gb/s 64MB Cache for DVR NVR Security Camera System with Drive Health Management and in-House Rescue Services (ST4000VXZ16/016)

So far this hard drive is working great for my NVR. I ran Smart checks after I installed it and everything checked out.

As with tech I'm always worried about dead on arrival stuff coming into the front door. However, Seagate drives have never done me wrong. This drive is no exception to their excellence in making hard drives. Its got good speeds, formats fast, and is perfect dimensions for my Unifi system. Great value as always from sea gate.

Worked like a charm in my Ubiquiti UDM SE. I only wish I bought a larger capacity drive.

I thought this dive was dead out of the box as it would not spin-up. Latest ssd specification assigns pin#3 on the power connector for spin control which was previously 3.3V. So if you install any new ssd on an older system it will never spin-up. The most common fix it to put tape over pin 3, or just cut the orange 3.3V wire to the power plug. I nearly returned the drive as dead when nothing was wrong with it. Now it is works perfectly. There should be an application note about this included in the box.

Did not work right out of the box. Clicking, and shut down my system. Quick return and refund by seller.

Great product, easy to install

Very good price, it's very useful for my mass storage needs, I really like the speed it handles

You can't go wrong with Seagate!

Muito bom o Produto. Recomendo

I needed to purchase a new hard drive for my security surveillance system, and the Seagate Skyhawk is highly recommended for this purpose. This arrived relatively quickly as there was a long wait time for the WD Purple which is also highly recommended for security surveillance. The 4TB is a big upgrade for my Lorex system and it has performed flawlessly so far and much quieter than the old drive it replaced. Drive came packaged properly and securely, brand new for sure, and fit perfectly.

Buen producto, funciona bien.

I bought the Seagate SkyHawk 4TB drive to use as backup storage for my surveillance system, and it has been running 24/7 without a single issue. It is designed specifically for constant recording, and you can tell — it runs cool, stays quiet, and never skips a frame. Installation was simple, plug it in and it was recognized instantly. The transfer speeds are consistent, and it handles multiple video streams at once without hesitation. For systems that write data non-stop, reliability matters more than raw speed, and this drive nails that balance perfectly. I have used Seagate drives for years, and the SkyHawk line still feels like the safest bet for anything that needs to stay on all the time. After months of continuous use, no errors, no heat problems, and no noise beyond a soft hum. If you run any kind of camera system or NAS for backup, this is the drive you want to set and forget. Tested for surveillance system backup, excellent reliability and stable performance under 24/7 operation.
