What type of storage should you choose for your photo library? It’s the most important question facing you when you set up your backup routine. This section covers the pros and cons for some digital media that are good for backups. See Table 7-1 for a summary and cost comparison.
Note
The storage capacity estimates in this chapter are based on digital photos about 5 MB in size, which is typical for a 5- or 6-megapixel camera.

CDs (CD-R)
A single disc is 700 megabytes and holds about 140 photos. CD-R discs are a better choice than CD-RW discs because they’re cheaper and you can’t accidentally erase your photos once they’re saved on the disc. “RW” stands for “rewriteable,” which is a geeky way of saying you can always change the contents of a CD-RW disc.
