With an external SSD, you can transfer files super fast. You can connect these hard drives via a USB-A, USB-C, or Thunderbolt connector. You can transfer files 5 to 20 times faster with an external SSD than with an HDD, because an SSD doesn't have moving parts. Are you a gamer? Choose an external SSD with a 2000MB/s read speed or higher. This way, you're not bothered by long loading screens.
