Western Digital 4TB WD Purple Surveillance Internal Hard Drive HDD - SATA 6 Gb/s, 64 MB Cache, 3.5" - WD40PURZ

Great product! Great price!

Bought one of these for my surveillance DVR in July 2018 and it was still going strong when the DVR was replaced in November 2022. New DVR had Seagate Skyhawk that died shortly after 2 years so going back to WD Purple.

I bought this item because the hard drive on our Hikvision NVR was failing already. The installation took maximum 5 minutes, it was an easy plug n play. For the price you can’t beat it!

excellent product,

Good value and this appears to be a good drive. Easy installation. Didn't come with a SATA cable so heads up if you are expecting to add this as a second hard drive like I was. It doesn't seem like the tiny cost of including that is worth the hassle it causes for the customer. The only other negative was Amazon's new and unexpected requirement to send a code number for delivery. That delayed my delivery for an extra day and was a real hassle since I actually work for a living and don't sit around the house waiting for Amazon deliveries. Both times they sent the code just 2 or 3 hours before the driver attempted to deliver and my company doesn't appreciate me having to mess with personal email to receive codes and then, because of an additional Amazon hassle, find someone else who can be there with the code to receive the package. I'm really coming to find working with Amazon to be more of a hassle as they implement new policies. My last Amazon purchase resulted in them delivering the wrong product and, since I wanted the product rather than a refund, it turned into a giant mess that they never did resolve. Against my objections, I just received a refund and a promise to help resolve it which they never kept.

Tried several hard drives TiVo couldn't format any, keep getting all lights flashing. Finally ordered WD purple 1TB and 2tb. TiVo could not format 2tb but formatted 1TB. After formatting and play the drive was very loud, but after 2 days it became very quite. Everything seems to be working perfect. I tried the WD green drives which are scrubbed clean but stopped working 90 days from purchase. Amazon refunded price. Tried a WD green 1TB. TiVo would not format. Research on drives had all kinds of answer for why these drives didn't work. The used ones had to be scrubbed completely clean for TiVo to format. Some drives come with an automatic shut off and TiVo can't handle this(PISH?). Each of the drives I tried were recommended drives. My only recommendation is just keep trying until you find one that works, and buy from Amazon, so you can return for refund.

No complaints on this one. Tons of storage and or got my security cameras back online after the last hard drive finally died after several years.

Being a Fan of Western Digital I decided to give their Surveillance Hard drive a try.. I currently have 9 cameras running constantly at my home to keep my property protected. And I had a 1tb drive on my system and had only 4 days of backup which these days is NOTHING.. I now have one day over 2 weeks or backup.. Totally going to upgrade to a 12 tb once I can get it. worth its weight in gold.. Just remember you're not going to be able to do a visual inventory of your stuff every day but with a good NVR and a large hard drive you will be able to periodically check your stuff and notice differences and catch what is going on. The larger the Hard Drive the better chance you have to keep a good eye on your stuff and have evidence in case of a situation. My situation is odd due to having a multitude of resolutions. Honestly All of my cameras (except 2) are from the Same Manufacture and I love them.. Probably shouldn't mention S3VC cameras but sorry gotta say excellent cameras for any good NVR (AMCREST) My cameras have resolutions from 1080 to 5 mp cameras(oldest camera is 720 ). Including a great camera from FOSCAM (which I didn't know it had audio) So you may have 4 or 6 cameras which most people get Standard resolution cameras (which are fine if your just wanting to see what happened without enough resolution to see who it was in most cases) I go 1080 or higher just so I can get good visuals of who or what happened with better ability to see what your protecting. So in a situation with 6 cameras at Standard Definition you will have at more than a month of recording easy. This drive is designed for Security camera recording and should last longer than a regular system drive. Will recommend to anyone who is in the market to buy a hard drive.
