Why this configuration
A 4TB PCIe 3.0 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.
4TB starts to replace juggling several smaller drives.
Usually chosen for: budget builders, laptop upgraders and anyone leaving SATA behind.
Good fit: large libraries and archives on a single drive.
