It may be tempting to think that in this day and age of Netflix streaming, Dropbox data-transfer, and Spotify music streaming that the optical disc has been declared extinct. But the optical disc, be it a CD, DVD or Blu-Ray, is still hanging on as an unalterable archive medium and as a cost-effective way to deliver audio and video content in a collectible packaged form.
In the case of video-based content, the optical disc still remains as a sure-fire medium of viewing this content offline which would be of benefit when you are travelling. You may even find that you could pack a movie or a season or two of your favourite TV series in the briefcase or laptop bag to have ready to binge-watch during that long-haul international flight without worrying about how much of the Ultrabook’s small SSD you are taking up.
A Windows Central article highlighted and compared a selection of USB-connected external Blu-Ray burners that can work with computers that don’t have any form of optical-disc reading or writing built in to them. Most of these units are slightly larger than 2 CD “jewel-cases” and they connect to the host computer via a USB 2.0 or USB 3.0 cable depending on the unit. Some of them implement a USB “Y-cable” as a way to solicit extra power from the host computer but you may find that a self-powered USB hub or, in a portable context, a high-capacity USB external battery pack connected to the “power” part of the cable could serve as a way to keep these optical drives powered when used with a host computer that has few USB connections.
These, like other USB storage devices, will present to most operating systems using the USB Mass-Storage device-class driver but do come with at least DVD-playback or advanced optical-disc-authoring software but you can use other software to do the job. Most of these Blu-Ray burners have the ability to burn to the 100Gb BDXL discs which would earn their keep with archiving a large amount of data. Some of these devices even write to M-Discs which are an optical-disc variation that is optimised for long-term archival storage.
Those of us who have a computer with an integrated optical drive may find the external optical drives good for such tasks as adding an extra optical drive for disc-to-disc copying, ripping a multiple-disc CD set to FLAC or extending the optical-disc capabilities of your existing computer. Here, this situation may come in to its own with laptops, all-in-one computers or low-profile desktop computers. Similarly, these optical drives could become a fail-over measure if the internal optical drive failed.
What is being proven with these portable optical-disc drives is that the optical disc still exists as a medium for data-archiving or distribution of collectable content.
