Manufacturers use environmental testing chambers to simulate the aging process and gauge the effects of temperature, humidity and other factors. The problem is delamination a breakdown of the adhesives that bind the disk. Every company has multiple lines of products buy the premium quality. I wouldn't buy from weird companies. Even if the information on your removable media remains intact, it will be useless if hardware to read that disk isn't available down the road.
Companies can stop making particular models of drives, or can go out of business outright.
For example, in 1998, Syquest, once the leading manufacturer of magnetic removable-media drives, filed for bankruptcy, creating headaches for users who needed repairs or additional media. To prevent committing priceless data to an obsolete medium, it's wise to choose a storage option that doesn't lock you in to one company for instance, CD-R or other optical disks. Another insurance policy is to make multiple backups on different kinds of disks. Saving those honeymoon pictures on both CD-ROM and Zip offers twice the chance that the data will stay readable. In the short term, no storage decision is final if something better comes along, you can copy the data to that new medium.
