Why this configuration
A 500GB USB TLC DRAM 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: everyday all-rounder use, from OS drive to game library; workstation and creative loads that hammer random I/O.

The parts, explained
500GB is a comfortable OS-and-games starting point.
USB and Thunderbolt portable drives trade peak speed for pocketability and cross-device use.
TLC NAND is the mainstream choice — a solid balance of endurance, speed and cost.
An onboard DRAM cache keeps the flash mapping table on the drive, holding random performance steady under sustained load.
