    Which one to get?
    Before reading any review read this: there is a key problem with the way this section is set up. For some reason it lists a very old (2014) model of this drive along with the same New Generation improved model. What makes that bad is that the user comments are both mixed together, so any problems with the original drive appear right on top of the list and may be misleading. It’s very important then to look at the tiny print at the top of each comment and see if the user is talking about the Old Generation style or the New Generation style. To be clear, I am talking about the improved New Generation style.If you are not already familiar with the difference between a general purpose hard drive and one designed for video security let me start with a very basic comparison. This comparison is very broad and not a textbook definition by any means.HOW IT WORKSComputers write and read their information to a hard drive in tiny chunks that are scattered randomly all over the disk, so the recording/playback heads are constantly jumping from place to place. Speed of access in a computer is extremely important. On the other hand video surveillance recorders write and read their information more like an old-fashioned tape recorder, pretty much just like what the cameras are seeing in real time. The recording/playback heads are only required to jump to another spot on the disk when you want to play back an event. So random-access search time is far less of a priority than the non-stop grunt work of recording dependably 24/7/365 without a hiccup. The two processes are entirely different job tasks.COMPARISON: BRAND A VS. BRAND BThere are two major brands of specialized video surveillance hard drives. My NVR is one of the most respected out there for users who have a lot of experience and they chose to use the other brand of hard drive. Kudos to them because many other video security manufacturers believe you’ll never know what’s inside so they install the cheapest no-name generic hard drive they can buy. I’ve been buying this brand of security system for years and have been very happy with it and when I wanted to increase my drive capacity from 2TB to 4TB I had no idea if switching to a WD brand drive would make any difference at all. Engineers told me that the two brands are not identical in their design philosophy, each brand considering certain design parameters to be the slightly better way to go.IS THERE A DIFFERENCEBecause the NVR software, firmware and other factors play at least as much of a role in performance as the hard drive I was looking to improve these things:1. Drive noise2. Drive heat3. Stuttering (when the image suddenly jumps or drops a few frames, usually on playback)I measured the operating temperature both drives in real-life use in identical conditions using a precision instrument. The original drive was operating at 97.7 F and the WD measured at 91.6 F. That 6 degree difference is significant but not substantial.Likewise I used a calibrated sound level meter for each drive. The original drive came in at 47 dBA. The WD was at 46.9 dBA, virtually identical.The last condition is more difficult to quantify because stuttering is sporadic, so in my opinion I would classify any differences in a typical use scenario as atypical, was I experiencing fewer or more instances of stuttering or about the same? I tried to make my comparison without prejudice for or against either brand because I really don’t care whose name is on it. I bought the WD primarily to double my recording capacity and hence the number of days it would record events. That being said in real-life everyday use I have to lean slightly toward the WD as having fewer instances of jumping, stuttering or frame dropping in my particular system and it does seem to handle a few second backspace more smoothly than the original drive. Maybe another way of putting it is that the WD seems to be playing nicer with the NVR’s software/firmware than the brand the manufacturer originally spec’d.WILL IT IMPROVE MY SECURITY SYSTEMThe short answer is not really. Any differences in operating temperature and noise level are too close to be significant and both brands are optimized for video security so abnormalities like stuttering are just that, and are not completely attributable to the hard drive. We can say categorically that the brand or type of hard drive you use will not improve the image resolution (picture quality) of your system.BOTTOM LINE SATISFACTIONAll things considered the WD is consistently a few bucks more than the other brand and I’m not a big fan of ever paying more if I don’t have to. So based on the few things I could measure and one that I could only perceive I have to say I do like this drive and I believe I made the right choice.
