CDs and DVDs for Data Storage?

Both CDs and DVDs offer simple yet safe way for backing up important data without any expensive investments. Let's take a closer look at how they may be used, and which safety issues may arise when using these optical storage devices for backup.

Once so popular CD (Compact Disc) and its writable versions CD-R and CD-RW have been available for quite a while. First CD-R recorder was produced at the end of the eighties, first Yamaha CD-R recorder cost about $35,000. Technology becomes cheaper over time and, now, the same recorder costs about $20. Although DVD (Digital Versatile Disc) came into use a little bit later, it still hasn't completely replaced CDs.  There are even more advanced technologies available today, like higher definition DVDs, called Blu-Ray, but they are aimed at quite specific use cases and will probably not become mainstream, since newer technologies are taking over.


It is widely known that DVDs hold about 6 times more data than CDs but it does not mean that CDs are obsolete. The great thing is that both CD and DVD reading and writing devices have become more versatile, making it possible to use different discs in the same device. Since both are so widely used, there is no danger that CD or DVD readers will disappear. 


Cheapest of all mediums

One of the benefits of using either CD or DVD for data storing is their cheap price. When buying CDs or DVDs in bulk, one DVD-RW disc might cost only 40–50 cents. Discs that are not rewritable are about three times cheaper. It means that the storing of one Gb of data will cost you only 3 cents (DVDs store 4.7 Gb of data). As history has shown, the cost of data storing can only get cheaper. 


CDs and DVDs, also known as optical discs, are easy to carry around, and you can easily  relocate them. They offer a simple and cheap way to protect your data from fire, theft and other local accidents. Certainly external hard drives, flash memory cards and USB sticks also serve the same purpose but they are many times more expensive. 


To choose the right backup medium for your data, you also need to consider a particular medium's reliability. Choosing quality brands like Verbatim or Philips is a good bet. For example see Verbatim CD-R 100 pack or DVD-R 100 pack.  What are the specific risks related to CDs and DVDs? They are popular among users because if a CD is accidentally dropped, it usually works fine afterwards, which can not be said about external hard drives. This fact is especially true if CDs are stored in protective case. Optical drives are technically quite different from hard drives and can not be damaged by strong magnetic fields. 


Greatest risks related to CDs and DVDs

Some sources mention damages caused by direct sunlight and high temperature. Even more problematic is that CDs are extremely vulnerable to scratches. One deep scratch may damage a disk to the extent that it becomes useless. Keeping disks in protective sleeves or in strong boxes is the safest practice. Many experts have expressed their concern about optical disks’ long-term reliability. Sure, they haven't been around more than a few decades but in our experience CDs with fifteen-year-old data on them are still working pretty well. 


The capacity of DVDs and CDs might not be the best for storing a massive number of raw image files and movies, but they are still worth  considering if you need to make backups of your important everyday files and folders. Keep your discs protected from scratches, avoid direct sunlight, and you can definitely use your valuable data for decades from now.
