External storage connects to an external port, such as a USB, IEEE 1394, SCSI, or eSATA. External flash drives, sometimes called thumb drives, that connect to a USB port are a type of removable storage. There are several factors to consider when purchasing external storage:
- Port type
- Storage capacity
- Power requirements
External storage offers portability and convenience when working with multiple computers. Choose the correct type of external storage for your customer’s needs. For example, if your customer needs to transfer a small amount of data, such as a single presentation, an external flash drive is a good choice. If your customer needs to back up or transfer large amounts of data, choose an external hard drive.
