Often, such media have the lowest possible quality level due to years of price struggles between manufacturers. In case of emergency, your files can even be read with an electron microscope.ĭo CDs and DVDs have a future as a means of long-term archiving? You can definitely say: no, if they are bought on the computer market or in a regular store. In contrast to all of the above, storing information on 'blank discs' has the advantage that the procedure for writing and reading data is completely standardized. And who can promise that this OS will work on our computers for the next ten years? The same can be attributed to the 'cloud' technologies: no one guarantees us the prosperous existence of Google or Amazon in 20 years. It is unlikely to survive after disappearing operating system Windows. In addition, the NTFS file system, which is almost universally used for data backup, was developed by Microsoft and is not an open standard. And even if you just wrote data to them once, these media will lose their charge in just a few years.Īt choosing a tough disk as a means for long-term archiving, other points should be taken into account - in particular, the possibility of corrosion on the contacts. In day-to-day work, they can withstand, as a rule, no more than 10,000 rewriting cycles, after which the flash memory resource is exhausted. Solid state hard drives have no moving parts, but their memory cells are far from eternal. They also cannot stand vibration and shock. Hard drives are not immune to numerous external factors such as dampness and heat. We'll also take a quick look at other methods that also promise to store files securely. All of them guarantee the safety of your files for a period of 100 to 1000 years, and if certain conditions are met, even longer. We will present three such technologies in the article: two types of rewritable disks and a specially prepared flash drive.

However, there are several relatively expensive solutions for long-term archiving of important files. This leads to a paradoxical result: important documents, photographs and videos are placed on media that cannot be trusted. However, about 43% of users save their files on media that is even shorter than optical discs. Today, the most popular long-term storage method is DVD. It is even more difficult to accept the fact that the data stored on a hard drive will physically disappear after years - these drives have a short lifespan. Our mind is hardly capable of comprehending such a magnitude. Thanks to the emergence of the latest technology, there are now more reliable digital repositories of information. Until now, we have stored our most important files on hard drives and DVDs that have a shelf life of only a few years.
