Yes, just expose each disk as an individual OSD and you'll already be better off. Depending what type of SSD they are - if they can sustain high random write IOPS you may even want to consider partitioning each disk and create 2 OSDs per SSD to make better use of the available IO capacity. For all-flash storage CPU utilization is also a factor - generally fewer cores with a higher clock speed would be preferred over a cpu with more cores but lower clock speeds in such a setup.
