What is an External Cd/Dvd Drive
Our age is the age of increasing performance capabilities and at the same time of minimizing sizes for portable electronic devices. Every manufacturer strives to make their products smaller, and often it means sacrificing some features. More and more laptops nowadays come without optical disc drives, and Ultrabooks are the whole class of devices that does not have this type of drive. But some people are not ready yet to give it up for USB drives and Cloud Storage. Several software products are released on optical discs only even today. The CD/DVD drives are on their way out, but there is still a necessity for them. For this very reason, manufacturers come to release external CD/DVD drives to connect them to laptops and Ultrabooks. With an external DVD drive, you can always read, copy, or write (burn) an optical disc. An external DVD drive easily connects to any computer with a USB 2.0 port or newer. Even if the DVD drive of your personal computer has been broken, you can simply replace it with a USB external DVD drive. And with their small sizes and light weight, the external CD/DVD drives can be used anywhere and anytime.
If your laptop has only one USB port and you prefer using the mouse (so, your USB external CD drive can’t be connected), then you need a USB hub for additional connections. The hub will multiply the number of your USB ports. And if you like the USB flash drives but need more storage space, then you will find it useful to look through our external hard drives review with their hundreds of Gigabytes of data right there in your pocket.
What Features to Compare
When you are looking for an external DVD drive, firstly look at its Drive Type. It lists the types of discs you will be able to use, so think about what discs you will need to use before buying. There are three types of discs that are the most popular: CD discs, DVD discs, and Blu-ray. By ways of using different technologies, these types of discs differ in the amount of data they can store. For example, you can write up to 700 MB of data on a CD disc, but on a DVD disc, you can store up to 4.7 GB, and Blu-ray is suitable for storing up to 50 GB of data. You should decide how much information you plan to burn on a disc. If it's just a small video or a few hundreds of photos, then a DVD drive is more than enough for you. These discs are very popular and widespread. And for high-quality and high-resolution video, backup copies of your operation system, or data storage Blu-ray discs will be more suitable. Large storage space of such discs will handle these tasks best. It stands to reason that different types of discs require different drive types with different technologies. When you purchase a DVD supporting device, you will be able to run both DVD and CD discs. But such drive will not read a Blu-ray disc. Choose a Blu-ray supporting drive, and any of the types we mentioned above will be accessible to you.
Another important parameter for any external DVD drive's performance is its reading and writing Speed. Manufacturers usually indicate it by numbers with an "x" letter. The "1x" speed of a DVD disc means 1.32 Megabytes per second, and for a Blu-ray disc, it is 4.5 Megabytes per second. What you see in reality is that an 8x DVD drive burns a whole disc in 7.5 minutes. A 6x Blu-ray will burn a standard disc in 15 minutes. The numbers are not unchangeable, the writing time depends on the file type and the quality of the disc itself.
As your external CD/DVD drive is something that is often seen, its Design also matters. The market offers a wide variety of external DVD drives, you will surely find the one that meets your preference. If you plan to carry the USB external DVD drive with you, be sure to note its size. When you choose the size right, it will allow you to put the device nicely in the pocket of your bag or pouch. And the light weight will make it so that you don't need to doubt whether you should take the external DVD drive with you or not.
