I think it is safe to say if you have a good general performance with 
the storage it also performs well with oVirt.

Therefore it might be the wrong place to ask; however, block sizes are 
only one of many factors in storage domain performance. No one but 
yourself or an expert at your site can answer this for you.

I would direct you to the excellent [iozone] utility witch leverages 
much of the testing for you.

Hope that helps,
