A Standard Hard Disk is engineered to read, write, and transfer data simultaneously. Whereas a Surveillance Hard Disk is engineered to perform write operation for the maximum part of its life, as the Hard Disks used in the surveillance system is used to write data 90% of the time and 10% for playback.
What is a surveillance hard drive?
Surveillance drives are meant for recording video on 24/7 security systems. They typically use something called a network video recorder (NVR). Unlike a PC, these drives have to be writing dataspecifically, video dataall the time.
Can we use normal hard disk in DVR?
While a surveillance hard drive forms a central component to the digital storage of surveillance video. It can be used in a DVR, NVR, Video Server or a Video Management System in order to work 24 hours a day and 7 days week. These hard drives need to be always active, in order to keep video evidence live.

How long do surveillance hard drives last?
three to five years
The simplest answer is that they can run smoothly for three to five years. This means any HDD, whether it’s external or inside of a system. Asking about the longevity of an external enclosurea metal or plastic housing designed to cover and protect a disk drive from damageis a different question altogether.
Is surveillance HDD good for PC?
Yes you can. They are pretty expensive than normal internal HDDs because they are more efficient. It has its own cache and it would be like using an Airbus to carry 2 passengers. if you wish to use it as PC HDD.
Is surveillance HDD good for Nas?
NAS and surveillance HDDs are engineered for the less-demanding workloads typical of surveillance or central network data storage. Consequently, NAS and surveillance HDDs sit between server-grade and desktop-type drives, both in terms of workload capability and price.
Can I use SSD for surveillance?
Durability: SSDs can be utilized in locations that require more rugged construction, such as surveillance systems that are located outdoors or at sites where there is the possibility that they would be subject to vandalizing.
Can I use SSD for CCTV?
SSD hard drives are almost immune to the effects of shock or vibration which again makes them a good choice for certain CCTV recorders.
How long will a 1TB hard drive record?
DVR+ (CM7500) with a 1TB external hard drive will record up to 180 hours of High Definition programming. HD content uses much more data space than SD content.
Which is better NVR or DVR?
The difference between DVR and NVR systems come down to the cost, how the data is transmitted, and type of cameras. NVR systems tend to have better picture quality, as well as easier installation, increased flexibility, and native support for audio on every camera that has a microphone.
Which lasts longer SSD or HDD?
SSD Reliability Factors to Consider. Generally, SSDs are more durable than HDDs in extreme and harsh environments because they don’t have moving parts such as actuator arms. SSDs can withstand accidental drops and other shocks, vibration, extreme temperatures, and magnetic fields better than HDDs.
Do hard drives go bad if not used?
The magnetic field can wear down or break down over time. So, it is possible that the hard drives go bad without use. Hard drives have moving parts, which are lubricated in some manner or form to avoid friction.A hard drive will absolutely deteriorate if it is not been used for several years.
What are signs of hard drive failure?
Common signs for a failing hard drive include sluggish performance, unusual noises (clicking or loud component sounds), and an increase number of corrupted files. These are textbook symptoms for the inevitably of a failing hard drive and action should be taken quickly to save your files from being lost.
Can I use SSD for DVR?
SSD’s have no mechanical heads to move around so information travels at the speed of light. This makes your tablet feel a lot more responsive even with a slower processor.So, with higher costs, lower reliability and no increase in performance, solid state drives just aren’t a good deal in a DVR.
What is NAS in hard drive?
A network-attached storage (NAS) device is a data storage device that connects to and is accessed through a network, instead of connecting directly to a computer.The beauty of a NAS device is that it can be easily accessed by multiple people, multiple computers, mobile devices, or even remotely (if set up properly).

The Purple is “Optimized” for recording Video.The Purple is “Optimized” for recording Video. (Writing data) A Network Video Recorder is basically a NAS for video and the WD Purple is used in those.
What is the difference between NAS and enterprise hard drives?
The enterprise line focuses on reliability, larger capacities, and higher performance when used for specific applications such as NAS or data center operation. Red drives are built for use in NAS units, while Purple drives work best in surveillance systems that require excellent write performance.
Can we use SSD in NVR?
I recently “built” our own NVR that has 4 ports of POE on board plus a dual nic. with Ubuntu and running Spectrum. We use this for small systems 4-8 cameras and use an SSD in it. Typically these systems are in homes, and the clients want ultra fast/smooth playback and that’s what you get with an SSD.
