These CDs are circular in shape and can store data and information around 650 MB it can hold up to 74 minutes of songs with a particular size of 120 millimeters (4.7 in).

But it has been observed that CDs had been easily replaced by DVDs and other storage mediums.

Disadvantages of CDs

The sizes of compact disks are 600 MB and 700 MB as all of us know that in this modern era the data used today is enormous.

Therefore the size of CD is not capable to store the amount of data present in this modern world.

Therefore DVDs, pen drives, and hard disks have replaced them easily as they can handle and store large amounts of data/information with ease.

2. Damaged

The CDs are circular in shape and made of some kind of plastic which is not that strong and can be easily broken and gets damaged easily.

This is the primary concern when using CDs.

The CDs are not completely secured and the data information inside them can be stolen and can be replicated or even someone can make illegal copies of your information and misuse them.

According to me, it is one of the disadvantages of CDs.

5. Scratched Disk

A disadvantage of a Compact Disk is that if it gets too scratched, it will not be able to read properly.

This CDs are very delicate in nature and therefore it is highly recommended they must be used with high level of caution as it has the tendency to get scratches easily.

On March 31, 1997, digital video disc (DVD) video players were first released for sale in the United States.
Digital optical disc data storage format was invented and developed in 1995 and released in late 1996.

DVD stands for Digital Versatile Disk DVD or Digital Video Disk can store around 7 to 10 times more data than simple CD (Compact Disk) as they are capable of storing huge data and information they have become more and more popular compared to Compact Disk.

A simple compact disk stores data around 640 MB whereas a single layer DVD comes with a storage capacity of 4.7GB and a double-layer DVD comes with storing capacity of almost 8GB to 18 GB.

This optical disk is cheaper and can handle huge data efficiently. They can store data permanently. Double Layer disks are used because they can store huge volumes of data.

Advantages of DVDs

1. Large Storage Capacity

The DVD (Digital Versatile Disk or Digital Video Disk) comes in a huge capacity to store data.

The necessity to store or handle a huge amount of data and information has led the manufacturer to produce high-quality DVDs with enormous storage.

The DVDs are also called secondary storage devices. The normal DVDs come in the size of 4.7 GB to 12 GB which is staggering.

You can be rest a sure that there will be more advanced DVDs with the capacity to store data will also be enhanced because of the heavy demand by the users.

2. Availability

The DVDs are readily available in the market because of the mass production by the manufacturer and also they have flooded the market with high-quality DVDs and with low cost.

The DVDs are available in a small shop as they are household stuff nowadays.

3. Low in Cost

The raw material to manufacture DVDs is very cheaper these days. Therefore the manufacturing cost drops incredibly when manufactured in large quantities.

 The computer peripheral industry is considered the most competitive industry around the globe.

Due to their competitive nature, the companies offer great prices and deals on their products which eventually help the users.

Therefore according to me, this is the major advantage of DVDs and therefore they are used in abundance.

4. Quality

The DVDs were previously used for storing images, sound, and videos they grew popular because of the quality they maintained while accessing and producing results.

The DVDs have excellent quality and can store data permanently.

The data inside DVDs can be read and access with the help of DVD-RWs which are also cheap and can be purchased from the local store.

DVD-RW is easily available in the market with a variety of manufacturer providing their products in competitive prices.

Disadvantages of DVD

1. Dependency

This DVD can be read-only when your computer or laptop has a DVD-RW installed on it

So this disk has major restrictions and according to me, it’s one of the important disadvantages of the DVDs.

2. Storage

Although the storage capacity of the DVDs is good the amount of data and information is played by the users is enormous.

Therefore the DVDs lack the space to store the data. The games and software these days are so huge that modern DVDs are not capable of handling this data.

And hence modern storage devices like hard disk and pen drives have replaced them comfortably.

3. Read Only

The normal DVDs are read-only in nature that means once the data is recorded or burned into the DVDs it cannot be replaced delete or update.

Yes, of course, there are some DVDs which are reusable available in the market which offers that they can delete, update data after storing and can be used multiple time.

These DVDs are very costly and cannot be used daily.

4. Data Safety

This is considered to be the major disadvantage of DVD as the data present in the disk can be easily copied and one can make as many copies as he wishes.

The data violation can happen when you lose your disk.

5. Easily Get Damaged

The DVDs are made of thin plastic-like material which can break easily. These disks when used for a long can have scratched on their surface which makes this disk not read the data properly.
