CD-RW

Overview

A CD-RW is a rewritable optical disc, which means that data can be written and erased many times. A CD-RW is ideal for creating reliable and convenient backups of all files and documents. Typically, CD-RW discs can hold about 700 MB of data or 80 minutes of audio. The rewritable optical discs are ideal for storing highly important data that undergoes constant updates. You can easily erase old or unwanted data, so you do not need to constantly buy new CDs.

Rewritable compact discs are generally inexpensive and can be reused. A 25-pack costs less than $20. Most computers come with a CD/DVD burner that reads and writes both CDs and DVDs. An internal CD/DVD burner costs around $40, and an external drive tends to cost around $60.

If you do not need a permanent copy, you should consider using a CD-RW. Keep yourself organized by making a list of important files and keeping track of what files undergo frequent updates. Figure out what is easily replaceable, irreplaceable, and everything in between. You can then streamline which files to backup on a CD-RW.
