Correct Answer. C. If the USB-C port on the device supports Thunderbolt 3 Not all USB-C ports support Thunderbolt 3, which provides significantly higher data transfer speeds up to 40 Gbps.
The first check should be whether the device's USB-C port actually supports Thunderbolt 3, as this could be the limiting factor in achieving expected high speeds.
Option A is incorrect because while it's important that the SSD supports Thunderbolt 3 to reach maximum speeds, the more common issue lies with the port capabilities of the connecting device.
Option B is incorrect because while cable length can affect performance, Thunderbolt 3 cables are typically capable of maintaining high speeds up to the maximum length specified by the standard (0.5 meters for passive cables at full speed).
Option D is incorrect because the power output of the port is unlikely to affect data transfer speeds; it's more relevant to charging capabilities.
