Advantages and disadvantages of internal and external CD burners?

Internal CD burners are generally more compact and can offer faster data transfer speeds, as they are directly connected to the computer's motherboard. However, they can be difficult to replace or upgrade and may not be as portable. External CD burners, on the other hand, are more versatile and portable, allowing use with multiple devices. The downside is that they can be slower due to USB connections and may require additional power sources.
