Documented selection limits

Match the exact connector at each end, cable length, interface generation and host/device requirements. Published data rates, power ratings and display modes are maximum conditional limits, not guaranteed application results. A physically matching connector alone does not establish protocol, charging, video or device compatibility. Match drive form factor, thickness, host interface/protocol and power needs; an adapter or bracket does not include a storage drive unless the exact SKU explicitly states it.
