Which is more permeable sand silt and clay?

The finer material holds more water. The granular size of Clay, Silt and Sand are in this order (smallest to largest):

1. Clay
2. Silt
3. Sand

So Clay holds the most water, then Silt, Then Sand.

This can be disproved if one is dry and the other is wet or other variations of this idea obviously.
