Why this configuration
A 500GB USB SSD is a portable, take-anywhere configuration. External SSDs trade a little peak speed for the freedom to move data between a PC, console and laptop without opening anything up.
500GB is a sensible OS-plus-a-few-games size.
Usually chosen for: backups, working off an external drive, and console storage overflow.
Good fit: mainstream desktop and laptop builds.
