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.

It’s been working fine for a few months with no problem with a Reolink NVR security system.

Nice HDD for good price, I am very much satisfied.

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.

Purchased to replace the old video 2TB HDD for a video 6TB HDD to gain more storage space on the NVR. Was easy to install and setup initially and all connections were easy to identify. Everything was working great as I had data from August 13, 2025, to October 4, 2025, but the new 6TB HDD only lasted 2 months and then would not read or write data. I tried to recover the data from the HDD but it will not even load when plugged into my PC.

After two failed fraudulent drives from the WD Purple line ordered from Amazon I finally found one that appears to be both legit and functioning. The first WD Purple I ordered showed 0 power on hours but clearly had been used previously. It was loud, clicked a lot and failed within two weeks. The replacement drive I ordered (That appeared to come from the "Western Digital Store") showed up and wasn't recognized by my system as a WD drive but rather an HGST drive...a model that was manufactured from 2014-2015. The drive had tool marks that had been painted over with black paint and the body also matched HGST drives from that era. You could even see sticker residue where something was removed and a WD Purple label was placed on it. The serial number was fake and also didn't match what SMART reported. WD had no record of either serial. This drive formatted immediately, showed up in new manufacturer packaging and the serial number checks out on the Seagate website. I've used several purple drives in the past with good results but it seems like Amazon has an issue with the resellers on this site so I would 100% avoid buying the WD line on here for now and go with this seagate drive instead.

My last Segate lasted over 7 years running 24/7/365. So far it has been a year and there have been zero issues and it is very quiet in my NVR. Worth spending a little extra now to prevent less heartache later on with a bad hard drive.

You can't go wrong with Seagate!

Verry good works fine with my udm pro

Muito bom o Produto. Recomendo

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.

Montato senza problemi. Funziona perfettamente. Soprattutto venduto e spedito da Amazon. Il che significa che in caso di problemi.... non ci sono problemi! Diciamo pure che l'ho comprato proprio perchè venduto e spedito da Amazon. E, non secondariamente, la qualità del prodotto è nota e riconosciuta. Per qualche euro di più rispetto a un venditore del Market Place, onestamente, ho imparato la lezione
