Blu-Ray vs. DVD – Difference and Comparison Between Blu-ray and DVD
Although both are optical storage formats, there are significant differences between Blu-ray and DVD. However, the principal difference is in streaming quality and storage capacity. Well, we’ll have a lengthy discussion on which one is better and what’s the difference between Blu-ray vs. DVD? Before that, we want to give you some in-depth knowledge and a basic understanding of them.
What is a DVD?
The first thing we have to know about is what DVD stands for? Well, DVD stands for Digital Versatile Disk or Digital Video Disc. Moreover, it is an optical disc that can store and view films, songs, and other data. Hence, it can hold almost 5 GB of storage and store almost 7x more data than a traditional compact disc.
Further, DVD’s image quality and random access are much superior to CD. The most prominent thing about DVDs is that they can hold almost 720p resolution video as well as MPEG-2 compression. You can’t run DVDs through a CD drive. It means you need a DVD drive or player to run it.
Additionally, the era of DVD mainly started in the mid-90. It was developed in 1995 and released in the following year for use. The most notable thing about DVDs is that they can store more data than CDs and deliver high-quality pictures.
Pros of DVD:
- Highly durable
- They can contain a considerable amount of data, unlike CDs
- Affordable
- It supplies a higher resolution of the video
Cons of DVD:
- The audio quality is not up to the mark
- The storage capacity is lesser than modern Blu-ray versions.
What is Blu-Ray?
Blu-ray is widely known as Blu-ray Disc (BD). It is designed to hold a much higher amount of data, even more than DVD. Hence, it is capable of storing a couple of hours of high-quality videos. It is called “Blu-ray”. But why? The reason is it is a blue laser used to read the disc.
As a result, it can store data much higher density than the red laser used in DVDs. The blue laser has a much smaller-sized wavelength than the red laser. For this reason, it can hold information in a short-sized place. Blu-ray was first introduced in 2006 and is manufactured by the Blu-ray Disc Association (BDA).
It is a significantly improved version of the DVD. Blu-ray single disc can store 35 GB storage while the dual disc is capable of holding 50 GB space. You’ll be able to see the depth, various shades of color, etc., when watching a Blu-ray movie. It is much better than DVD in terms of quality and storage capacity. You’ll feel the extra attraction when you enjoy a film on Blu-ray!
Pros of Blu-Ray:
- Five times higher storage capacity than DVD
- Superb quality video and audio
- A perfect format for films and documentaries
- Blu-ray can deliver a more excellent backward compatibility.
Cons of Blu-Ray:
- It isn’t reasonable like DVDs
- It supports the 3D format

We’ve previously said that Blu-ray can contain much more data than DVDs. The difference is enormous. A single DVD disc can store 4.7 GB of data. So, what does it mean?

Additionally, the wavelength of the red laser is around 650nm. Contrariwise, the Blu-ray discs use a blue laser instead of red. Its wavelength is 450 nm. It means that Blu-ray’s capability of reading data information is much more accurate and sophisticated.
