Does Windows dynamic disks read in parallel?

Everywhere they write that with a mirrored volume, writing to disks goes in parallel, but it became interesting to me, but does reading also go in parallel from two disks?
Is it possible to read simultaneously from two disks one large file or two different ones?
I did not find such information, maybe someone wondered and conducted tests?

Reading from a soft mirror also goes in parallel from two disks at once, and the data is verified so that they do not differ.
Two different files cannot be read.

Depending on the capabilities and settings of the raid controller. Some allow you to increase the read speed on mirrored arrays by reading from different disks.

Today Artem conducted tests completely right, there is no increase in productivity.
