That is for a bipolar transistor. A Mosfet is the opposite. Look at all the different names for the regions in Wikipedia.Not sure where you got this old chart, but isn't Saturation on the Left side of the curve where Vds approaches zero?

You understand it backwards. Since a turned on Mosfet has an extremely low resistance then for a very small drain current the Vds is also very small. Its Vds is also fairly small when its drain current is fairly high which is the same for a mechanical switch.for very small Vds in my case, the drain current should also be very small
If Vds is in loop with V+ and low impedance in series,
the current will be according to Ohm's Law
with all the loop resistance include RdsOn and supply & load series resistance.
According to the datasheet, minimal Vds for 1 A is about 100mV. Just Ohms law.But according to datasheet it is not possible to draw more than 1A for such small Vds.
