Why this configuration
A 128GB 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.
At 128GB this is really a boot or cache drive rather than a main library.
Usually chosen for: write-heavy secondary roles and keeping older machines useful.
Good fit: mainstream desktop and laptop builds.
