I used it as a hard drive in a surveillance DVR. It only failed after 2 ½ months. It started with typos and I reformatted it. It never worked again. Worst of all, this hard drive was a replacement for another purple WD that failed after just 18 months. Since my NAS has been working flawlessly with Seagate hard drives for over 2 years, I will switch brands. Western Digital just isn't reliable enough. Reading other reviews I think the heat is the problem. DVRs have poor ventilation and I think…

This drive has been running for over a year and a half with 3 cameras feeding it 24/7. A 1080p camera, a 960p camera and a 480p camera at 25-30 fps. The drive works great and is very write and temperature stable (used in Mac Pro). Videos may take a little longer to load, especially while recording, depending on disk activity and file size.

I bought several purple 2GB, 3GB and 4GB drives. All are out of warranty. They just can't handle the constant CCTV footage.

I do not recommend purple discs. I recommend buying enterprise drives for about 40% more. Purple drives are rated at 180TB per year. Enterprise drives are rated to…

Upgrade a 2014 Tivo Roamio 500GB Series 5 to 3TB in about 30 minutes. No problem. Did an easy upgrade, just removed the old drive and kept it - just in case there were problems in the future - then put "rails" on the new drive, installed, put the cover back on and plugged it in. Wait a moment . The Series 5 will fully format a new blank 3TB drive for you (when it sees a blank drive) and if you're connected to the internet it will look up your MAC number in the file and register the device…
