What are the advantages of a SD Card or USB Flash Drive?

• SD Cards or USB flash drives are more robust than CDs or DVDs as they are not susceptible to scratches on the disk, which can damage stored content

• They can also be used several times unlike blank CD/DVDs which can only be saved onto once (This excludes re-writable CD/DVDs which can be re-used but the quality is affected)

• They tend to be faster than writing to a CD/DVD which can take up to 15 mins or more to create

• Very portable and can plug into nearly all computers for access
