Why this configuration

A 400GB 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.

Usually chosen for: budget builders, laptop upgraders and anyone leaving SATA behind.

Good fit: mainstream desktop and laptop builds.
