Why this configuration
A 128GB PCIe 3.0 ADATA 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. ADATA specifically tends to be chosen here for its firmware track record and warranty support.
At 128GB this is really a boot or cache drive rather than a main library.
Usually chosen for: budget builders, laptop upgraders and anyone leaving SATA behind.
Good fit: mainstream desktop and laptop builds.
