Optical drives are outdated. They should have been removed completely when USB flashdrives of sufficient capacities were available.
Sigh...
I still have an OD in my laptop, but I basically never use it.
The only time I needed it was once in the past several years, and even then, it was because someone else who primarily uses optical discs needed some help.
I keep trying to tell people 'get rid of it, its uselessly occupying the space inside a computer, especially when there are flash drives and external hard disks that can save your data in much larger quantities, read it far faster, and there is no danger of the data suddenly becoming unreadable (unlike on discs which are prone to scratches, etc.).
I find it absurd that some universities, etc. require data copying onto the optical discs, especially if the data is only a few megabytes large - its a waste of media for one thing and an email would have been faster.
