Yes, if you can manage *cost* , separating journal on a different device should improve write performance. But, you need to evaluate how many osd journals
you can dedicate to a single OSD as at some point it will be bottlenecked by that journal device BW.

On a full ssd cluster , is it meaningful to put the journal on a different drive ? does it have any impact on performance ?
