i need to read 2 adc channel simultaneously

Scanning really doesn't do that.

If I needed 10 samples from TWO channels, I'd probably look to pair ADC1+ADC2, and use an advanced TIM that would do a 10x One-Shot (Repetition Count) 

A 5 MHz sample rate, and a 500 KHz interrupt rate, sounds like a fun project.

2x 480 cycles for sample, wouldn't that be closer to 44 KHz than 5 MHz?
