Why this configuration
A 1TB PCIe 3.0 Western Digital 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. Western Digital specifically tends to be chosen here for its firmware track record and warranty support.
1TB is the capacity most single-drive builds settle on.
Usually chosen for: budget builders, laptop upgraders and anyone leaving SATA behind.
Good fit: everyday all-rounder use, from OS drive to game library.
