Why this configuration
A 250GB PCIe 3.0 Plextor TLC SSD is an affordable NVMe step up from SATA. Gen3 is roughly six times SATA's throughput yet often costs little more, making it the easy default for a first NVMe drive or a laptop that only supports Gen3. Plextor 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: budget builders, laptop upgraders and anyone leaving SATA behind.
Good fit: everyday all-rounder use, from OS drive to game library.
