Review: Great hard drive, installed on a PC to manage IP camera recordings - We purchased this hard drive to add another hard drive into our Dell PC. We record wildlife in our garden - 20 cameras recording 24/7 and were concerned our hard drive was getting a hammering! We ordered this drive, it arrived the next day as we are Prime Members, arrived in a plastic bag within the desertcart box. We followed a video on YouTube which advised how to install it and within a few minutes it was up and running. It’s now been installed for a month and we’ve not experienced any problems 🤞. It’s a great size at 4TB and is providing us with about 11 days of footage before it overwrites. When researching this hard drive, everyone on here said it needs to be installed on a CCTV system, but we can testify that you can install it on a PC to manage cameras that are constantly writing to a hard drive.
Review: Very reliable - Western Digital, one of the most reliable HDD's I've come across. Thank you.

## Questions & Answers

**Q: Will this work in a annke system**
A: Hi Yes, I installed this Purple WD Hard Drive in my Annke 4 Camera DVR box in January. Easy straightforward install - open case, click the flying cables inside the case to the drive (it’s obvious where they go), and secure the drive inside the case. Been trouble free since Jan. 19. Hope this isn’t the ‘kiss of death’ 😉. D

**Q: After How many days will start rewriting itself?**
A: Good morning, 

depends on the number of cameras connected to the DVR, their resolution and the type of recording you make (H24 or motion detection), and the video compression of your DVR. 

Cordially

**Q: I’m planning on using this to increase storage on a swann cctv system, i take it this will be ok?**
A: In my opinion, yes.
This should be checked in the swann manual.

**Q: Where do I get a power cable for this?**
A: Just Google 'Sata Power Cable'. You will get many hits.

### ⭐⭐⭐⭐⭐ Very reliable
*by S***4 on 23 June 2026*

Western Digital, one of the most reliable HDD's I've come across. Thank you.

### ⭐⭐⭐⭐⭐ Seems a good drive, but let's see for how long.
*by W***T on 11 November 2019*

Use this drive for my CCTV system. Had it running a couple of months and so far it's doing the job well. But I've been around computers for over 40yrs and have had many, many HDs fail, so I won't be holding breath.
