There are many different forms of digital storage, and each one has it's pros and cons. The most common form is magnetic storage, which is what you find on your hard drive or a floppy disk. It's really good at storing data and can hold a lot of it. However, it is not very stable. Magnetic storage degrades over time, meaning that the longer you use it, the more unreliable it becomes. This means that you need to frequently back up your data and/or replace your hard drive fairly regularly. Another form is optical storage, which stores information as a pattern of pits on a surface such as a CD-ROM or DVD. Optical storage is also not very stable, as discs can be scratched easily. But optical storage drives are cheap and easy to use (you probably already have one in your computer.) Optical drives can also read from many different types of discs, which makes them versatile. Finally there is tape storage, which records data onto magnetic tape like the kind used for analog audio cassettes. Tape storage is great for recording large amounts of data quickly, but accessing information on tape takes longer than accessing something stored on magnetic or optical media.
