Is journaling the same as log assisted (or at least really similar to)?  

Isn't the point of journalling/logging to group writes to offset positional
latency on the device??  If so, an SSD should have the same latency no matter
where you position to on the device.  So an SSD eliminates (or at least
significantly) reduces the point of journalling  ... no?  Or am I in the wrong 
discussion?
