An "eSATA" (External Serial ATA) standard allows for connecting external storage devices like hard drives to a computer using a cable that can be up to 2 meters (78 inches) long. This essentially brings the high speeds of internal SATA connections to external peripherals, making it a faster option than traditional USB connections at the time of its introduction.
