Is CD DVD storage media the right option for storing your digital memories? This is an important question nowadays as many of us accumulate many Gigabytes of electronic files on our computers. For many people, this is the only thought that is given to storage i.e. download the files to a laptop or desktop computer and then forget about them. However, if we truly want to preserve electronic files such as emails, spreadsheets, word processing documents, digital photographs, digital audio recordings, digital video recordings, and others, then a more concerted effort needs to be undertaken.
The most basic thing to do is to make a copy or copies of your information. Having a single copy of your files on your computer is very risky. Hard drives generally have a short lifetime of about five years on average, but this is only an average figure. Hard drives can fail very early on in their lifespan and failures often occur suddenly and without much warning. If your only copy of your digital photos and other digital memories and important files, etc., were on this hard drive then the information would be lost. In some cases, hard drive restoration companies may be able to retrieve some or all of your digital files, but this is not always possible and ultimately would cost thousands of dollars to do so.
It is recommended to have two and for maximum security three copies of your information. One copy can reside on your computer, another copy on different media can reside close by, and a third copy on the same or different storage media than the first two, ideally should be located offsite. This brings us to the question initially asked: is CD DVD storage media a good option for preserving your digital information? When discussing this type of storage media we are specifically talking about recordable CD and DVD discs (often referred to as CD-Rs or DVD-Rs).
Now there are certain key factors that determine whether CD DVD storage media is appropriate for the storage of your valuable files or not and three of these are summarized below.
If CD DVD storage media does not have enough capacity to meet your needs, then this can create problems such producing too many discs or having to spread related information (such as a video recording) over more than one disc which is very inconvenient. CD-Rs are okay to use for information such as word processing files, emails, spreadsheets, up to medium quality digital photographs, and reasonable quality audio files, for the most part. Single layer DVD-Rs will accommodate all of these files, in addition to being able to store reasonable amounts of high quality digital photographs and digital audio, and lower quality video. High quality video can only be stored in small amounts on a standard DVD-R. I would not recommend the use of dual layer DVD-Rs or DVD+Rs due to compatibility and longevity issues.
Some CD-Rs and DVD-Rs have a relatively short lifetime of around ten years or less, while others such as the gold discs have lifetimes of 50 to 100 years or more. Depending on your needs, select the lifetime range that works best. Approximate lifetimes for some discs are provided below.
When it comes to lifetime of CD DVD storage media, the longevity of the playback or reader technology is also an issue. Without the equipment the media cannot be read and the information is essentially lost. Although there has been a decline in the production, sales, and use of optical disc media, optical disc drive production is still on the rise. In addition, new generation drives such as Blu-ray drives are backward compatible with CD and DVD optical discs and so CDs and DVDs can be read by these drives. Many new drives are being produced and many older drives exist and so the threat to not being able to read CDs and DVDs in the future is currently very low.
is always a factor in the decisions we make. When it comes to storage media, it
is not an issue if only small amounts of information need to be stored, but as
the amounts increase it is a factor to look at. For CD-R DVD-R storage media
listed in the lifetime section above, approximate costs as of 2015 are provided
below on a price per disc basis. These cost figures were derived from buying in
bulk or in other words spindles of 50 or 100.
As you can see the cost of the gold media is substantially more. This is not a large issue if only using small amounts because the benefits of high longevity are undeniable. However, if using a lot of these discs, it may be quite an expensive option.
