External storage devices
External storage devices such as hard drives, USB flash drives, Compact Discs (CDs) and Digital Video Discs (DVDs), can be an attractive option for storing your data due to their low cost and portability. However, they are not recommended for the long term storage of your data, particularly, your master copies as:
- Their longevity is not guaranteed, especially if they are not stored correctly, for example, CDs degrade, tapes shrink in the long term. They can be easily damaged, misplaced or lost.
- Errors with writing to CDs and DVDs are common.
- They may not be big enough for all the research data, so multiple disks or drives may be needed.
- They pose a security risk.
