Why this configuration
A 250GB Crucial 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. Crucial specifically tends to be chosen here for its firmware track record and warranty support.
250GB covers an OS and core apps with little room for a large game library.
Usually chosen for: write-heavy secondary roles and keeping older machines useful.
Good fit: mainstream desktop and laptop builds.
