Buy drives cheaply: consumer tips
You can install a drive in a desktop PC or use it via USB on a subnotebook or netbook. Especially small mobile computers often do not come with a reader for optical media. Purchasing an internal drive is mainly necessary if the old component is defective or outdated. We will show you the features of various drives.
Optical drives as a central element of computer entertainment
Optical drives read CDs, DVDs, or, in newer versions, Blu-rays. At first glance, they do not differ much from CD or DVD players, but the usage options are generally more extensive. A drive is an integral part of desktop PCs. Also, notebooks from 14 inches upwards have a corresponding component. This is usually located on the side of the notebook. The practical accessory can not only play optical media but also write to them. For this purpose, the drive has a laser that transfers data to the disc.
Read and write speeds of DVD burners
When you buy a new internal drive, it usually uses the significantly faster S-ATA interface compared to IDE. The component is located in the computer case in a bay at the front and is equipped with a grey or more commonly black bezel. On the bezel, you will find a button to eject the CD or DVD, a reset button, and status LEDs. The read and write speeds can vary. For high-quality drives from LiteOn, LG Electronics, or Samsung, they are often similar. A drive can read a DVD at an average speed of 16 to 24 times and write at eight times speed. Access to CDs and CD-Rs is correspondingly faster.
Blu-ray drives and burners write HD videos quickly and quietly
With an internal Blu-ray burner, you can also write HD videos to an optical disc. This way, you can burn holiday videos recorded in Full HD and play them on a Blu-ray player. The interface is similar to a DVD burner, but the laser is more powerful. The approximately eightfold reading speed may seem almost twice as long at first glance. Upon closer inspection, Blu-ray burners also write quite quickly. Consider the amount of data that can fit on a Blu-ray. Depending on the model, this can be 25, 50, or 100 gigabytes. Therefore, it is no surprise that writing to a Blu-ray disc takes a moment.
Internal or external, DVD or Blu-ray – advantages at a glance
With an external Blu-ray burner, you are very flexible. The drive is backwards compatible and reads not only the blue discs but also DVDs and CDs. The same applies to the writing function. With a Blu-ray burner, you can write various formats. The speeds are slightly lower than internal drives but are more than adequate. Additionally, you can connect an external drive via USB to any computer. No special installation is required.
Tips for buying a new drive
- Check the system requirements
- Some drives and burners come with additional software
- In addition to a fast writing speed, a high error correction rate is also recommended
- Buy an affordable DVD burner if you do not want to write Blu-rays
