Why this configuration
A 250GB SATA SanDisk SSD is a budget and compatibility choice. SATA won't win benchmarks, but it's the cheapest way to add solid-state speed and fits essentially any PC or laptop with a 2.5-inch bay. SanDisk 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.
