Closing, as it not fixable. 

> as you can see, flash disk sometimes mount secondly

This only means that sometimes the flash drive gets ready before the left 1TB 
drive, so it is assigned (by the kernel) the next available drive letter.

I guess that if you change the left and right drives, then the smaller 500GB 
drive (in the left bay) would appear as sda instead.

This is out of Alt-F control, it is the kernel responsibility. And as Alt-F 
doesn't use udev, a "persistent" rule can't be used to force drive letters.

PS-You can see the drives spinup time using SMART (Disk->Utilities->Health)

solution!
