Why this configuration
A 250GB SATA Western Digital SSD is a budget and compatibility choice.

Western Digital 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: reviving older machines, cheap capacity upgrades and second drives.
Good fit: budget upgrades, older PCs and second drives.
Look elsewhere for: large-file creative work where NVMe pulls ahead.
