Why A Surveillance System Hard Drive is needed For The Surveillance Security System

Why Need A Surveillance System Hard Drive For The Surveillance Security System


A surveillance system has to store large amounts of data. It runs intensive management software. It is very important to choose a surveillance system hard drive. Selecting hardware that is professionally designed is the best for your surveillance system. It can eliminate the chance of hardware failure.


A solid-state drive (SSD) uses different technology to remove the spinning parts while a traditional hard drive also has spinning disks. SSD has no moving parts and will last longer.


This is a comparatively new technology but has not been extensively tested in the video surveillance system. You have to choose a professional type of hard drive for the surveillance system. Nowadays, a few manufacturers produce “surveillance-grade” or “server-rated” hard drives.


How much HHD space you will need depends on how long you like to store your data as well as your surveillance system area. You may lose your important video due to the shortage of storage capacity.


So it is always best to be equipped with as much space capacity as possible. Consult with your surveillance security expert for designing your surveillance system. When part of your system fails, a professional surveillance system with a RAID setup can prevent the loss of your important data.


Difference Between A Normal Hard Drive and Surveillance Hard Drive

You may think that you can use a normal desktop hard drive for your surveillance system. You may feel that all hard drive operates similarly but this is quite wrong.


Traditionally a desktop hard drive is made to operate for around 8 hours. So the overall workload will be around 10%-20%. It is a low-moderate performance.


On the other hand, a surveillance system’s hard drive plays a vital role. It generates a central component to the digital storage of surveillance system video. It works 24/7 and it can be used in a DVR, NVR, Video Server, or Video Management System.


A surveillance system hard drive often offers a high mean time between failure ability. The surveillance hard drive moderates high and medium use and affect multiple users. Some hard drive manufacturers offer a service plan to recover the data from the failed hard drive if they are damaged due to mechanical or accidental cause.


We suggest that you use an exclusive surveillance or professional class hard drive for your surveillance system. Use a DVR embedded with a surveillance hard drive for the scale of a video surveillance system that is equipped with a few HD cameras.


Importance Of A Surveillance Hard Drive

Nonstop Surveillance

A good hard drive that is specially designed for a surveillance system can record 24/7 nonstop in your DVR/NVR system.


Unlimited Storage

You do not need to change the surveillance hard drive once installed. If your security camera is reliable then you can use the same hard drive. Just format the hard drive every two months. If it has a loop recording format then you would do nothing at all for increasing the storage space. It is similar to a free cloud storage package.


Lifetime Use

A normal hard drive has a minimum 45000 hours lifetime but a surveillance hard drive can be used long term. It allows double or triple power-on hours capability, which means it can last for a long period and much longer than any other hard drive device.


Fast Recording

A surveillance system works on ethics, if you have configured the settings then they record only when slight motion is detected or they can continuously record 24/7.


Buying Guide

There have a few things that must be considered before buying a hard drive for your surveillance system.



A better brand’s hard drive provides you with better service. So you should choose the best brand that can supply you with a great surveillance system hard drive. We recommend Western Digital. WD is a well-known brand all over the world.

It is very important to check the RPM of the hard drive before buying it. You must buy the highest RPM offered by the hard drive. It can start from 5300 RPM. The rotation allows the drive to record at a high speed.


Workload Capacity

A surveillance system is designed with at least 3 cameras. That means you need the best hard drive for better and more reliable performance. To choose the best one you need to read the reviews and description.


Storage Capacity

How much storage capacity is required in the hard drive for your surveillance system depends on how many security cameras you need and how many times you like to store your data. Consult your surveillance system expert to establish the quantity that you need.


Fast Reading and Recording of Live Footage

Many people complain that their CCTV is not able to record live video. It can happen if you don’t have a surveillance hard drive or if your internet connection gets interrupted. A surveillance hard drive allows the camera a greater rotation and can record the data with more speed.


24/7 Nonstop Recording

A surveillance hard drive can record 24/7 nonstop. While some other hard drives aren’t able to do this.



A hard drive is part of an electric device that can be damaged anytime due to technical or hardware failure. So before purchasing you must check the warranty offered by the manufacturer or seller.
