Why this configuration
A 500GB Kingston MLC SSD is a legacy endurance choice. MLC stores two bits per cell instead of three, so these older drives take far more rewriting than a modern budget drive, at a much higher cost per gigabyte. Kingston specifically tends to be chosen here for its firmware track record and warranty support.
500GB is a sensible OS-plus-a-few-games size.
Usually chosen for: write-heavy secondary roles and keeping older machines useful.
Good fit: mainstream desktop and laptop builds.
