Hard drive failure is a reality, and replacing it ASAP is necessary to maintain your home and business surveillance system. Having a high quality and dependable security DVR hard drive is a must.

When comparing security DVR hard drives for your home security system, you will need to choose a high quality hard drive that will be able not only to handle your heavy recording use, but also to make it as easy as possible for you to view your videos. 

It’s important that you can clearly see who or what is on your videos so that you don’t have questions about who was at your home.

What good is having high resolution cameras if your hard drive can’t process the images?

One thing that you will want to consider when shopping is the capacity of the hard drive you’re considering. 

There are a number of online tools that are designed to help you determine exactly how much storage space you need so that you can easily record and view your security footage. 

By considering your preferred frame rates, recording resolutions, and utilization time, you can easily decipher how much video will be stored to your hard drive. 

Armed with this information you can be certain you have one that is large enough to meet your needs.

The size of hard drives available on the market varies widely. 

Some are significantly smaller and only offer around 500 GB of storage space, while others can offer closer to 9 TB, or even more.  

The greater your recording needs are, the more storage space you will need. If you are in doubt, it never hurts opting for more storage.

As a general rule of thumb, at least 1TB of storage is my recommendation.

Of course, you will find exactly what I did, which is that the more storage you get, the more expensive your new hard drive is going to be. 


It is imperative to make sure that you have ample storage space for your home security system to use so that you don’t have to worry about accidentally writing over important video footage. 

Doing so can cause you to lose the ability to show an important video to the police, which is necessary if you have been the victim of a crime.

When you choose a hard drive that is not only large enough to meet your needs, but also will easily store videos without overheating or dying, then you will have that sweet peace of mind that you can’t put a price on.

What to Look for in Your Security DVR Hard Drive

I’ve already discussed how important it is to consider the size of your new hard drive when  comparing security DVR hard drives, but it’s just as important to consider a few other factors. Depending on where your hard drive is going to be stored in your home, you will want to make sure that it is very quiet when in operation. Otherwise it can be very noisy, which is distracting.

Also make sure that you can use your hard drive in extreme temperatures. 

Some hard drives are better suited to use in hot weather, while there are others that can be damaged by high temperatures. Leading to failure.

Installing Your Hard Drive

Installing your new hard drive is generally easy and is the same for most models. 

You need to make sure that your hard drive and your security system both use the popular SATA connection because this will make it significantly easier to install your new hard drive.

After you find the female SATA port on your security system, you can easily connect the male SATA port on your hard drive to it. 

This will cause your surveillance system to recognize your new hard drive and start recording to it. 

If you have problems with this step, then it is very likely that your hard drive isn’t formatted correctly.
